13-003 5/7/2013 Ali Salih  I-Sport Dealer Installed Rear Spoiler on e36 M3 There was a clarification on e36 M3 rear spoiler in 2012 that deemed this part as dealer option and “widely available” thus OK to use. However, 2013 Rulebook doesn’t really clarify this part. Can you please clarify the use of this option in Sport Classes ? After further review of the 2012 clarification, the rear wing was determined to be a dealer option and is no longer available. The clarification was dropped at the end of 2012 5/7/2013
13-002 2/4/2013 Ali Salih  Rear Trailing Arm Bushing Material on Sport Classes. Is Monoball bushings allowed on Sport Classes? Rule book says p.35;
7-Suspension bushing material is free.
a. Bushing material does not include replacement of bushings
with spherical bearings or rod ends such as Heim ends except
as noted below.
b. Solid bushings are allowed if fixed in place and allow
rotation in a single plane or axis.Monoball bushings are not Heim joints, fixed in place and only allows in single plane or axis. I wanted to confirm that they are ok to be used. Thanks.		 Not allowed. Rules do not specially call out monoball bushings 2/4/2013
13-001 1/22/2013 Sam Mammano  Car classification Can you tell me why some 1995 E36 M3 are IP cars and others are JP cars?

In the rule book i only see this model classed as IP
Thanks

 Cars can be classified by horsepower and weight. It is possible to have a M3 with a non-M3 transplant engine. In this example, the car would move to a different class 1/22/2013
12-023 12/13/2012 Eric Heinrich  SE36 Rain tires for 2013 and forward. For SE36, I recommend adopting the BF Goodrich KDW-R tire in size 225/45/17 as the spec rain tire for the series. Not a clarification – Suggest a rules change. 12/13/2012
12-022 11/30/2012 Chris Lewis  Modified Gearbox Requirements Is a BMW gearbox housing that contains non-OEM gears and parts legal for Modified class? If yes, must the ratios be the same as the stock ratios? Thanks, Chris P. Lewis BMW gearboxes cannot contain non-OE gears. Reference Section 7.L.1 11/30/2012
12-021 11/25/2012 Chris Lewis  BMWCCA Number Panels Requirement Clarification Section 2.I.3 of the current rules states:

“3. Club Racing officials may require series and sponsor identification
(decals) in specific size, contrast, and placement to be displayed on
cars before being allowed on track. These requirements are
specified on the web site “General Information-for the racer”.”

The BMW CCA Club Racing site details the required markings for race cars.

http://www.bmwccaclubracing.com/Information/DecalRequirements.aspx

One of the requirements is the running of the BMW CCA Number Board for BMW CCA declared cars.

BMW CCA declared class cars are required to run the BMW CCA number board and sponsor decals, yet we have cars that are declared class cars (like SM) who are running a no number board at all. There are also several cars that have “morphed” the BMW CCA number board into something that is not even a close facsimile of the number board supplied by National. Can you please clarify if these decal requirements any longer exist. If they do still exist, then can they be uniformly enforced? I’m happy to not run the Number Board, but the current rules would seem to say that I “have to”. I put new doors on my car, so I’m happy to leave them off. Chris P. Lewis

 Number boards are recommended. However, in the absence of the number board the specifications described in General Rule 2.I.1 will apply. 11/25/2012
12-020 11/25/2012 Chris Lewis  Aerodynamic Aids in Modified Clarification Section 7.N.12 of the rules states:

“12. Underbody aerodynamic aids, other than those stock to the model
and chassis, are not permitted between the front and rear axles. Under
trays are allowed between the front of the car and the front axles, and
rear diffusers/venturi devices are allowed between the rear axle and the
rear of the car. Rear underbody aerodynamics must terminate no further
back than one inch past the rear of the stock bumper location as viewed
from above. If under-car fuel tanks have been removed, a panel that
duplicates the bottom profile of the stock tanks may be attached. These
panels must not extend past the location of the stock tanks more than a
small amount required to affix the panels.”

Is a Modified class car that has had all of its under body removed and replaced with a completely different structure than stock (between the axles) considered “aero legal” per this section? Chris P. Lewis

 No Clarification required 11/25/2012
12-019 11/25/2012 Chris Lewis  Partial Tube-Frame Construction Clarification Section 7.N.6 of the current rules states:

“6. Partial tube-frame construction is allowed. Construction must be
based upon factory chassis. VINs on the cowl and doorframe must be in
place, or the door sill tag must be intact if originally supplied. The A, B,
and C pillars must be OE both in angles, length, and location. Roof must
be OE. OE rocker panels must be used.
7. Non-critical sheet metal (spare tire wells, etc) may be removed.
Removal may not be primarily intended to provide aerodynamic benefit,
except between the front of the car and the front axles, and between the
rear of the car and the rear axles. Any sound deadening or insulation
may be removed, except as required around a stock fuel tank when it is
retained.”

There are cars being built that are almost completely tube frame that intend to run in the Modified Class. See the link below as an example:

OE transmission required in regular MOD, with any OEM gear ratio.The question is, are modifications to the OE gearbox allowed, such as in the case of making alternate oem gear ratios fit?		 Modifications to the gearbox not allowed. Modifications are not specifically called out in rules. 11/21/2012
12-016 10/5/2012 Mike Akard  Gary Davis asked me to submit a mid-season Rules Change Request today. Please RUSH!!! Gary Davis asked me to submit a mid-season Rules Change Request today. We are planning to have FIVE points races at the upcoming Savannah Speed Classic National Event (the one BMW NA has encouraged us to try to increase participation due to its high profile nature). It seems that our rule book currently (although already approved to change in ’13) limits to 3 points races at a National Event (two 150% and one 200% race). We should be permitted to have as many 100% points races as event schedule can permit since basically there is no down side for those chasing points as the best of 8 (now…best of 12 in ’13) has ALL of the 100% races being thrown out in favor of 150% & 200% points races toward any championship. We have already discussed and approved removing limits to any/all events…only one 150% Feature Race at regional, two 150% premium races at Premier Events, and a 200% Feature with two 150% premium races at a National Event. Any additional number of 100% points races at any event in any region hurts absolutely no one…can only be a benefit to advertise more races rather than practice time or “fun races” to improve participation! We are supposed to be focused on growing this thing…lets get this done ASAP! Points change was granted by G. Davis 10/5/2012
12-015 8/3/2012 JP Tracey  I sport classification Does an engine swap from a 95 M3 (s50 engine) into a chassis of a 92 318 allow the car to run in IS? I am unclear re the wording that the chassis and the engine must be as from the factory. thanks Not Allowed – Engine swaps are not allowed in Sport Class. 8/3/2012
12-014 5/14/2012 William L Mellott Jr  Rule clarification update/change request
RE: ASC+T system full removal disable – in Sport Class		 Is it allowable to fully remove the ASC+T system in the Sport class?

In an effort to equalize the Sport class series across all model years eligible; it is my understanding ASC+T was not available from the factory in early production (it

is my understanding ASC+T did not become mandatory or available until later model manufacture). Thus to equalize models without ASC+T and with ASC+T,

simplest would be to allow the removal of the ASC+T system, thus equalizing model years.

The best example is an E36 325 model, which did not have traction control in 92-94 production, but ASC+T became optional in the 95 production models. This will

cause a difference in year models of what is otherwise the same car. Removal is a 15 minute and $25 job, requiring removal of the additional AST+T throttle body

and replacement of the existing OEM rubber intake boot update to the correct OE boot for the same model.

This anomaly where traction control is performed with a secondary throttle body that affects power output only affects E36 model cars – older models didn’t have

traction control and newer models didn’t add an additional throttle body to control traction that also reduced power when not in use.

Thanks
Bill

  ASC-T throttle body may be removed in cars with the ASC-T systems installed 8/21/2012

12-010 3/12/2012 Robert McClaskey  Sport Class Chassis/Engine combination I currently have a 1993 325i sedan prepared to JS rules. Since my car is currently OBD I, can I legally put in a 1995 M3, S50 motor and race in IS? All other suspension/brake changes would be made as well. There is no competitive advantage and the weight for coupe/sedan is the same regardless of S50/S52. Engine swaps are permitted in Prepared and Modified Classes, and not in Sport Class. 5/9/2012
12-009 3/8/2012 Bob Gore  Wings on modified class cars I understand the rules on height, width and rearward limits on wings. The rules say they are otherwise open. Does this suggest that the wing being able to be adjusted while racing is OK?

Thanks

Bob Gore

  Wings are open in Mod Classes and may be adjusted while the car is moving.  Not allowed in Sport, Prepared, Spec E36 or Spec E30 classes 3/21/2012
12-008 2/16/2012 Eric Heinrich  valve jobs, redux So the actual clarification request for the below is, are valve jobs as part of typical engine/cylinder head rebuilding/refreshing allowed in classes other than Modified?  Valve job maintenaqnce is restricted to the original number of  angles on the stock valve.   Machining is allowed back to factory specifications. 3/21/2012
12-007 2/16/2012 Eric Heinrich  Valve jobs. All sections of the rules, with the exception of Modified classes, do not specify that machining of the valve is allowed in any way shape or form.

So, as it is, anyone that is reunning a rebuilt or refreshed motor/head in an class other than Mod, and had had a typical valve job done, is not legal.

In prepared, the rules do state the valve seat is free, but nothing is mentioned about the valve itself.

In Sport, SpecE36 and M3T, the rules are silent in regards to the valve and valve seat. So in these classes, anyone that bends their valves must only use a non-refreshed/repaired stock head and valves. machining the head/seat valve as part of any typical refresh/rebuild is not allowed.

 

 See RC-008 3/21/2012
12-006 2/16/2012 Eric Heinrich  Is REM Isotropic Finishing of the ring and pinion legal in Sport, Prepared, or SpecE36 classes? It does not appear to be, just want to make sure.
Thanks.		  Not allowed in Sport, Prepared, or Spec E36 classes 3/21/2012
12-004 1/18/2012 Eric Heinrich  same as below – differential language The Modified rules specifically state treatments/coatings platings are allowed, so this type of modification does not appear allowed in Prepared or Sport calsses thanks Treatments/platings/coatings not allowed. Lockup percentage is free.  Changing of ramp angle is allowed as per the functionaly of after market limited slip unit. 3/21/2012
12-003 1/18/2012 Eric Heinrich  Sport and Prepared class differential language and allowed differential modifications BMW CCA Club Racing Rules V17.5 – 01/01/2012
Page 36 of 157I. Differential
1. Ratio of the ring and pinion is free.
2. Non-factory limited slip of any type is allowed, including welding of the gears.
———————
Is the intention of #2 to allow for modification of lockup percentages and ramp angles, or does this also allow you to use aftermarket treatments/platings/coating (i.e. Mikronite/DLC/REM finishing etc)?		 Treatments and coating are allowed in Mod Classes but are not allowed in Prepared or Sports Classes 3/21/2012
12-002 1/4/2012 Eric Heinrich  M3T – allowance of 2.5L bottom end only Does this require the entire 2.5L bottom end?

Does this rule allow the use of a 2.5L block with piston oil squirters? (I recommend aginst this to keep percieved competitive costs down)

Does this rule allow the use of the crank only, with 2.3L pistons? (albeit impractical)

Does this rule allow for the use of a 2.3L crank with a 2.5L bore – (this would be the best option, allowing racers to salvage overbored blocks and run them without having to purchase the very expensive 2.5L crankshafts)

  Error and Omission – Langauge should be removed from M3T class to be consistent with Sport and Prepared class 3/21/2012
12-001 1/4/2012 Eric Heinrich  2012 Rules – autocross specific compounds Sport and prepared class no longer have the wording restricting use of “autocross specific compounds”

M3T does still have this wording. I suggest chagning the M3T wording to be the same as Sport and prepared in regards to tires.

  An EVO III block with oil squirters would constitute a Euro engine and should not be allowed. The intention was to extend the life of worn 2.3L US blocks by allowing overbore up to 95 mm 4/12/2012

11-012 11/3/2011 Brian Stein  M3T Declaration Sheet Update for 2012 As transition allowance GG.1 expires for 2012 the M3T Declaration Sheet needs to be updated to allow 284/276 cams and 11:1 compression at the 2550 lbs base weight for M3T and not a +50lb additional weight. This should be removed or (2) on the declaration sheet should read +0lb per rules 9.X.2, 9.X.3.

“GG. Transitioning Allowances
1. To facilitate competitive transitioning of 2009 JS, for a period not to

11-011 10/12/2011 Jonathan Adams  Air Jacks Can we add the ability to add air jacks to prepared and sport class cars? We would of course add this but disallow the ability to store compressed gas or activate the jacks from inside the cockpit. Air jacks offer no performance advantage with a mandatory pit time length, like we have currently. This would help racers that do not travel with a large “crew”.  On board Air Jacks are not allowed in Sport Class 4/12/2012
11-010 10/5/2011 Eric Heinrich  SFI standards clarification Will the rules committee please clarify why BMW CR requires replacement of interior right side nets every two years when no other organization does not?

Also will the rules committee please clarify why BMW CR requires HANS tethers must be replaced every three years when HANS own guidance says 5 years?

Thanks

 Since CR has always subscribed to the SFI standards when developing their own requirements, deviation from those standards could be considered negligence in a litigant situation. There is probably little defense in stating that “that’s what other series do”.

11-009 8/9/2011 Jim Banks  HANS tether expiration Section 3.K.5 (p. 25) of the 2011 rules states: “HANS tethers shall be replaced every three years or after any incident where the tethers have been elongated.” This is in contrast to HANS’ own guidance, which states the HANS tethers should be replaced every five years. Can we get standardization in 2012 on the manufacturer’s recommended replacement interval? Revised and incorporated in 2012 rules 4/12/2012
11-008 7/11/2011 Mike Akard  Sport class front bumper cover Rules specifically permit M3 covers being used on e30 & e36 cars so long as they remain within the same type chassis (e30 on e30 cars but no cross-generational swaps like e46 bumpers on e36 cars) including lip Spoilers, but not splitters. So, can a E46 M3 CSL front bumper cover be used on an e46 non-M car in Sport class as the rule seems to mention directly without specifically listing e46 M3 CSL?

 

 Not Allowed – CSL bumpers for E46 are not available in the Motorsport parts catalog for NA.

I wish to remove the portion of the interior console in front of the handbrake which houses the gear lever, window switches and hazard switch. This is a separate piece and does not require any cutting of or alteration to the dashboard.The rules say that the interior, which includes the console, may be removed as long as the dashboard remains intact. Please confirm that removal of the console is OK. Front console may be removed 4/12/2012
11-006 6/1/2011 Eric Wong  E46 M3 Roof Since the E46 M3 sunroof is glass and sport/prepared rules allow for replacement of the panel with metal. Does this include the allowance to replace the ENTIRE roof w/ a metal non-sunroof panel? Yes, the entire roof may be replaced with a metal non-moon roof panel. 4/12/2012
11-005 2/28/2011 Allan Lewis  Use of alternate roof panels The rule regarding the roof states “Chassis that have alternate OE roof panels may use any of the OE panels or exact replicas. The roof must be installed according to factory specifications.” But, to how is the chassis defined? By chassis code (E46 etc) alone? For example, an E46 M3 was available with a CF roof. Can a modified car based on an E46 330 therefore use that roof since it is the same chassis code? Not Allowed  – Carbon Fiber Roof:  Carbon Fiber roofs for any E46 chassis were not available in the US.

11-001 2/8/2011 Keith Feldott  C Modified engine size limit (3499cc). I currently have a C Mod E36 M3 with a 3481cc M60 V8 engine
(89mm bore x 70mm stroke).I am considering building a back-up short block using OEM components in order to reduce costs. This engine would use a standard bore block w/84mm bore and a standard crankshaft w/80mm stroke resulting in a 3547cc displacement, 48cc over the class limit of 3499cc.

In order to meet the class limit I would need to reduce the stroke to 78.9mm which results in a displacement of 3499cc. However, per Prepared rule 6.E.6 I would be permitted to overbore the block by .040″ which would yield a displacement of 3582cc.

My question is whether I can legally build the short block using the OEM components which yield a displacement of 3547cc, which is still 35cc less than the 3582cc overall limit?

My interpretation of the rules is that I should be able to do this based on the third sentence of the following Modified rule:

E. Engine
1. The car must retain a BMW OE engine block and head. Schnitzer heads are allowed on M10 engines. All other changes, relocations, substitutions, alterations, and modifications are free.

As long as the actual displacement is less than the maximum displacement allowed for the class a Modified class engine should be legal regardless of whether the increased displacement is achieved via increasing the bore or the stroke.

Thank you for your timely consideration of this proposal.

09-0014 4/30/2009 Gary Nakasato  Charcoal canister In prepared class, I see most cars not having one. When converting an OBDII car to an OBDI, there are no provisions to hook the OBDII charcoal canister to the OBDI set up. Is it legal to remove the trunk charcoal canister system in Prepared class, as they serve no function anymore? This has been deemed to fall under the provisions of 10.B.5, Errors and Omissions.

09-0012 5/19/2009 Jim Banks  Annual Tech Inspection under 3(B)(4) I am confused as to whether my Annual Tech Inspection, done last year at O’Fest, is valid for 365 days from that inspection or whether a new Annual Tech Inspection needs to be performed for the 2009 season. The section of the rules states in one place “ANNUAL TECH – All racecars … must undergo a comprehensive annual inspection … within the prior 365 days” while later in that same paragraph two references are made to “calendar year.” My first race is 8-9 June in NJ. Do I need a new Annual Tech? This has been deemed to fall under the provisions of 10.B.5, Errors and Omissions.

3.B.4 as reads:
4. ANNUAL TECH – All racecars in a BMW CCA Club Racing declared class must undergo a comprehensive annual inspection prior to participation in any Club Racing event within the prior 365 days. If a racer is unable to complete an annual tech before their first race of the calendar year, they must contact the Tech Steward assigned to their first race at least 2 weeks before the event to arrange an annual tech, either at the event (if mutually agreeable) or at another location. Before the annual tech inspection is performed, the car owner must complete the Annual Tech Inspection form and validate it with his signature. The Inspection form, logbook, driver safety gear, and car are then presented to an authorized Club Racing tech inspector either by prior appointment outside, or as early as possible at an event. Following successful completion of the inspection, the form will be signed by the inspector and stapled to the logbook. The logbook is then presented to the Tech Steward at each event for the remainder of that calendar year.

09-0006 2/16/2009 Jack Money  Prepared Class, Engine, Vanos system Years ago it was clarified/confirmed that NO CHANGES can be made to the Vanos system (E36 and other vanos cars). It seems that many people are still modifying them to limit timing (among other things).

From the rules, 6. Prepared Classes, 2. Engine:

“2. Camshaft lift and duration may be changed from stock. Cam gears and valve springs are free. Alternate valve retainers of the same material as stock and equal or heavier weight than stock are allowed. No other internal engine changes are allowed.”

There is no mention of Vanos at all in the entire CR Rules document. So can the Vanos be modified in any way or not?

Thanks.

08-0078 6/2/2008 David White  North American Challenge Events From page 100: “A driver may accumulate points in class from only one NAC Event per calendar.”

If a driver races in the same class at two NAC events in a calendar year, what determines which event the driver accumulates points from?

 Appendix G North American Points System
Points and Penalty Calculations
E. Position Points Multipliers.
2. North American Challenge Race.

As reads:
A NAC Event shall have Finishing Position Points awarded at 150% of the standard for up to three races. A driver may accumulate points in class from only one NAC Event per calendar.

Should read:
A NAC Event shall have Finishing Position Points awarded at 150% of the standard for up to three races. A driver may accumulate points in class from only one NAC Event per calendar year. If a driver competes in more than one NAC event in the calendar year, the one that produces the highest total points shall be used.

08-0076 5/29/2008 Gerry Sparks  Flags At a recent event, I received a one lap penalty for entering the pit for a
mandatory stop following a full-course yellow. At the time, the green flag
was waving at start/finish, and was visible to me at least one corner before
the pit entrance which was one corner before start/finish. The race steward
said that I should have passed the start/finish before I could enter the
pit.
I can’t find this in the rule book. The only relevant rule I see is:
Appendix E Racing Rules
3.E.2.a.Once the green flag is displayed, racing has
resumed…..
There is a separate rule
4.Rules Other Than Green Flag Racing
F. Red Flag
The pits will open after all cars have taken the

Does this rule regarding the red flag also apply to a full course yellow?		 Please see Clarification 08-0074 5/29/2008
08-0075 5/27/2008   Clutch 6.C. states that “The clutch and pressure plate shall be the same size” which is about as vague as pistons having the same configuration. Does this mean the clutch disc must be the same diameter in wording that other organizations use? Prepared Classes
6. Transmission/Flywheel Assembly

As reads:
C. Clutch may be lightened or replaced with alternate materials. The clutch and pressure plate shall be the same size and number of clutch disk(s) as originally equipped for the chassis, model and year.

08-0074 5/20/2008   Flags During an Enduro, in the event that either FCY or Black Flags bring out a pace car, can a car pit for its mandatory 5 minute stop as soon as the green flag is shown, or must the car complete a full lap after the green flag at start/finish before it can pit for the 5 minute stop? There have been two different interpretations of this in the past two years, in the SA region. In one case, we were told to complete a lap after taking the green. Recently at VIR, we were told that if the track is green, you can pit, so some cars who were well behind the leaders (and not up to pit entry yet) could pit as soon as the green flag was shown, but the leaders had to take a full lap.

08-0073 5/16/2008   Pit Stops “My question is about the number of pit stops required for a 90 minute enduro. As written the rules appear to be silent regarding the number of stops required for a 90 minute enduro, however a reasonable interpretation would be that 2 stops are required for a 90 minute enduro. As written it seems to cover less than 90 minutes and greater than 90 minutes. Just trying to think through strategy for my first enduro longer than 60 minutes. Thanks for the effort to deal with this and all of the other clarifications!
Section 5.A.5 states “”Endurance races of less than 90 minutes scheduled duration are required to have one pit stop. Endurance races of more than 90 minutes are required to have one additional pit stop for every 45 minutes of scheduled duration..”””

 

 

Appendix E Racing Rules
5. Enduro Rules
A. General
5. Endurance races of less than 90 minutes scheduled duration are required to have one pit stop. Endurance races of more than 90 minutes are required to have one additional pit stop for every 45 minutes of scheduled duration, e.g. a 120 minute enduro is required to have two pit stops and a 150 minute enduro is required to have three pit stops. All mandatory pit stops must be timed as wheels stopped for five minutes. Each team is responsible for timing its own stop. Organizers may have additional personnel timing stops, but they are not obligated to provide timing for competitors.

5.  Enduro
Rules

A.
General

15. If a race
is prematurely ended under Red Flag track conditions, no penalty or time
assessment shall be assigned to those cars which were in the pits when the track
condition was declared. Similarly, those racecars that had not yet pitted prior
to the track condition being declared shall not be assigned a penalty or time
assessment. Racers are reminded that the decision when to pit is theirs. Any
advantage or disadvantage associated with that decision is borne strictly by the
racer. Timing and Scoring will consider the order of entry of on-track racecars
into pit lane as to be that of the running order for the last scored lap,
subject to adjustment for any improper passes executed under the RF condition.

B. Red Flag
Conditions

1. Cars may
NOT begin or continue their mandatory 5-minute pit stop under a Red Flag (RF)
track condition. If a racecar has already entered hot pit lane when the RF
condition is declared, no pit activity may begin and ALL pit stop activity
already in progress must immediately cease (no service, no driver changes).
Pit stop activity for racecars already in the pits can resume when the RF
condition returns to full course yellow (i.e., the cars begin to return to the
course for a restart). Racecars that were in the pits when the RF condition
was declared may not exit their assigned pit until all other racecars that
were on track have reentered the track for the restart. All racecars that were
on the track when the RF was declared will be placed back onto the track
first, followed by racecars from hot pit lane in the order in which they
arrived in hot pit lane.

The
implementation of no Black Flag all for Races was not fully
completed.

The issue of time is one of the race
clock versus the wall clock.  Event organizers should designate which will
take
precident.

Aftermarket front one-piece bumper/air dam units are allowed provided the original crash bar is maintained OR the assembly is otherwise reinforced to equal strength as the original assembly.
Does this allow for super-lightweight fiberglass aftermarket E30M3 front bumper covers, (none of which currently available come close to the factory strength btw) or is the intention for it allow for aftermarket bumper covers, as long as they are of the same material (urethane)?
The following is a rules clarification.
The spoiler, which may be a one piece bumper air dam, material composition is unrestricted.

Omission:

Headlights may be covered with additional materials.

The following is a response to the second question that is being asked, the Rules Committee has determined that no rules clarification is necessary

There is no provision for them to be disconnected or inoperative.

08-0042 4/22/2008   Safety – Inside Net Safety Rule 7. C. states stock class cars may remove or alter the center vents or radio to facilitate installation of an interior, right side net. May other components of the center console, instead of the radio or center vents, be altered or removed to facilitate installation of an interior net? Yes, either the radio or OBC may be removed to facilitate the installation of the inside window net. 4/22/2008
08-0024 1/23/2008   Brakes At what stage of prep is this allowed? In Stock, “Removal or modification of dust shields is allowed” which if removed would remove the parking brake in the rear. In Prepared, Rotors are free, which would include rear rotors with no parking brake drum. Omission:  Prepared – The emergency brakes, mechanism and controls may be removed. 1/23/2008

Are FIA 1986 3 layer Nomex fire suits manufactured after 2000 with shoulder epaulettes allowed? BMW CCA Club Racing Rules as written require only specify FIA 8856.		 1.  Driving suits shall carry a rating of SFI 3.2A/1 rating or higher (3.2A/5, 3.2A/10, 3.2A/15, or 3.2A/20) or FIA 8856-2000, FIA NORME 1986/1986, or FIA 8856-1986.
a.   SFI suits rated 3.2A/1 must be worn in conjunction with full length upper and lower fire rate underwear.  This update is in the 2008 Rules V13.2.		 1/23/2008
08-0019 1/23/2008   Body/Chassis/Interior STOCK
“A passenger seat is required. The passenger seat must either be a stock seat or meet the same requirements as the driver’s seat.”
Does this mean that a passenger seat must also have a seat back brace if it is older than 5 years, and that there must be passenger 5 or 6 point harnesses that meet the same requirements as the driver’s side. (this would include HANS-compatible harnesses for the passenger seat)
(Aside from the fact that passengers are not allowed in any timed CR session, regardless of whether or not I use my race car to instruct.)
In other words, for stock classes, would a seat and belts that would normally be legal for the driver, with the exception of certification expiration dates, be okay for putting on the passenger side?		 The stock seat or a replacement seat must be in place.  A replacement seat need not meet the safety requirements of the drivers seat but must be recognized as seat capable of seating an adult. 1/23/2008
08-0015 1/23/2008   General Rules STOCK
Is cryo-treatment of parts allowed?		 Omissions:  Stock Classes  – Cryogenic treatment of any part or component is permitted.

“Air intakes, air filters and air boxes are free.”
Are engine air intake filters allowed to be removed?		 This is an error the item should read “Air intakes, air filters and air boxes may be replaced.” 1/23/2008
08-0001 1/3/2008   Differential & Suspension Are diff bushings and subframe bushings allowed to be replaced with alternate materials or solid bushings in Spec E36? 1.  The rear subframe is defined to be a suspension component and therefore falls under the suspension bushing provisions.
2.  Omission:  Differential mount bushings are free.
This applies to both SpecE36 and Prepared Classes.		 1/3/2008
07-0078 12/15/2007   Stock Wheel Width As later production E36 M3s were available from the factory with 7.5″ front and 8.5″ rear wheels, would it be correct to say that 9.5″ max width wheels are IS legal? Also, would it be correct to say that 9.5″ max width wheels would be legal on earlier E36 chassis prior to the 8.5″ wheel option? The plus 1 inch provision allows for 8.5 inch wide fronts and 9.5 inch wide rears on E36 M3’s. 12/26/2007
07-0077 12/11/2007   Points The rules are not clear regarding how penalties are applied to points standings.  It states that 20 points are to be removed but not from which total. Penalty applies to the drivers accumulated regional and national season points in the class for which the points would have been awarded.  Premier, National and North American Challenge events distribute points to multiple regions therefore the host region and the home region class points are effected for those type events. 12/26/2007
07-0076 11/30/2007   Prepared Interior Can I remove the glove box door and glove box from my prepared class car? Omission:  The dash must be intact but anything attached to it (vents, glove box, airbag cover (where appropriate), etc.) may be removed. 12/6/2007
07-0075 11/28/2007   Classification Where does an E46 M3 CSL fit and what weights must it meet? Since the E46 M3 CSL was not available to the general public though factory-authorized, US BMW Dealerships they are not eligible to participate in Stock or Prepared per Car Classification, Stock and Prepared, 1. General, (page 24 2007 rules).  Thus this model would fall into Modified.  Classification for Modified cars is by displacement and the classification table that precedes the Official Vehicle Specifications table. 11/30/2007
07-0074 11/19/2007   Mirrors Side mirrors are not addressed specifically in the rules. Are non-stock side mirrors allowed to be used in Mod? Are side mirrors required at all in Mod? Omission:  External mirrors in the Modified class may be replaced. 11/30/2007
07-0073 11/15/2007   Hoses Is “Aeroquip AQP Socketless racing hose” acceptable? While the hose does slip on to the fittings, once installed is impossible to remove. Hoses must be secured by a clamping device that ensures the line does not slip off the fitting. 11/30/2007
07-0072 11/6/2007   Windows Is there any provision for using partial or full lexan windows, specifically on the passenger side in Modified class? No.  The window openings of the front driver and passenger doors shall not be covered while on track specifically to provide ease of access for safety workers in the event of an incident. 11/30/2007
07-0071 10/31/2007   Classification May I change my 1995 E36 M3 from I stock to H stock class? If I do may I remove components from my M3 that are not on the 1995 LTW M3 (a/c, sunroof,radio, hood insulation etc) and add the LTW spoiler and splitter? No. The rules establish the class for the car General Rule 8 applies. 11/6/2007
07-0070 10/29/2007   Prepared Pulley I and several of my fellow racers have suffered a siginificant number of power steering failures on E36s. We feel one of the factors is driving the power steering pump continuously from 6000 to 8000rpm which it was clearly not designed for. Similarly, the water pump is probably not very efficient at 8000 rpm either. Can you please clarify if we are allowed to underdrive these components in Prepared (specifically HP for me)? Better hoses is one solution but excessive high pressure in the system is more likely the cause. There is nothing in the rules that specifically allows pulley changes in Stock or Prepared therefore they are not allowed to be changed. 11/6/2007
07-0069 10/25/2007   Vintage/Historic Page 19, 7C states the requirement for an interior net. My car is right hand drive. I use arm restraints and therefore no window net. What do I need to do? While we would truly like to see this and similar cars in the program the cars must meet our current safety standards or those specifically allowed per the rules, which include window nets (and interior nets beginning in 2008), full cages, six point harnesses, etc. 11/6/2007
07-0068 9/27/2007   SCCA Cross Overs I am running MP on a SCCA log book. SCCA does
not require an on board fire system, just a hand held unit.
Can I continue to run the SCCA rules?		 Yes. 10/22/2007
07-0067 9/23/2007   Classification Where do the Z4 M Coupe and Z4 3.0 Coupe fit? 10/19/2007
07-0066 9/9/2007   SpecE36/Engine Rule 1(E) in the SpecE36 section states: “ECU software is free so long as the ECU remains stock in every other way.” and “Devices that alter…the signals from the ECU are prohibited.” With this in mind, are aftermarket replacement ECU performance chips allowable so long as they directly replace the factory chip? Yes. 9/6/2007
07-0065 8/16/2007   Prepared/Engine Swap 6. The weight of an engine swap car must meet the greater of:
c. The weight of the heaviest version of that chassis in its class (e.g., an E36 318 or 325 chassis receiving a 2.8l motor must weigh as much as an E36 328).
If I take a 325 motor and put it in an e36 318, do I have to run the weight of a 325 or a 328?		 The vehicle must meet the minimum weigh of that which is created.  In the cited example, if one puts a 2.5l M50 into a 318 it must meet the minimum weigh of a 325. 9/6/2007
07-0064 8/23/2007   Stock Chassis/Interior I. Fender and wheel openings shall remain unmodified except that rolling under, flattening, or grinding any interior lip on a wheel opening is allowed for tire clearance purposes. Fender flaring is prohibited.–Does this mean that any inner fender liners installed by the factory must be present on all stock class cars, or is the intent to prevent modification to the structure of the wheel well, and plastic inner fender liners may be removed? The rule cited specifically refers to the fender prohibiting any modifications except for the interior lip of the fender for clearance for tires.  The rules are silent regarding fender liners, this is an omission, they may be removed in Prepared classes, not Stock. 9/6/2007
07-0063 8/14/2007   Prepared Chassis/Interior If passenger side door window (glass) is removed…is a door panel (stock or allowed material for IP) required? Yes. 9/6/2007
07-0062 8/4/2007   Stock/Engine “In an E46 M3, the mass air meter in the BMW parts catalog is part number 13 62 7 830 359, which is only what we would have considered the insert in the past. Since most air intakes for this car replace the housing, and the housing on the E46 M3 is specifically NOT part of the mass air meter, is this replacement of the intake/housing allowed in the rules?” Omission: Vehicles with a design that houses both the mass air meter (e.g. E46, E90) and the air box as a single integrated housing may change the housing, transferring the OE air flow meter to the new air box. 9/6/2007
07-0061 8/4/2007   Modified Transmission Rules currently allow BMW transmissions in modified classes. Does this include gearboxes such as the Getrag race boxes for E30 M3, E36, E46, etc that are BMW parts using BMW OEM housings with alternate gear ratios and internals, provided by the factory in a complete BMW unit? No.  The intent of “OEM” as used in this rule is actually Original Equipment or factory installed optional equipment available on standard (not limited or special version) production vehicles delivered to BMW authorized dealers for sale to the general public for use on public roads.  Racing specific transmissions, regardless of having BMW part numbers, are not Original Equipment independent of the source of the transmission. 9/6/2007
07-0060 7/30/2007   Enduro Rules p. 92 of the rules, f.2. state, “any change to the car or driver means the car starts at the back of the grid”. it seems to me that changing car class consitutues a car change and the car should have started from the back of the grid. is that what the rules intend? Yes. 8/4/2007
07-0059 7/25/2007   Prepared Gearboxes Are close ratios gearboxes allowed in prepared? Yes, euro spec/close ratio/alternate non US transmissions are allowed in prepared. However, these allowed transmissions must be from road going, dealer delivered and licenseable vehicles. No modifications to internals, including reinforced/upgraded/non OEM parts are allowed. This also disallows tranmissions specifically designed for racing including, but not limited to, Motorsport parts or Motorsport internals/cases. 8/4/2007
07-0058 7/25/2007   Clutch in Prepared are “multi-puck” clutch disks allowed? Yes, multi-puck is not multidisc, they are upgraded components which the rules for Prepared allow. 8/4/2007
07-0057 7/25/2007   Engine Swapping Would swapping either a 2.5 or 2.8 liter engine (from E36 chassis car) into an E36M3 chassis would result in a J-Prepared car (weighing in at 2970 for 2.5 or 2995 for 2.8 [steel block]). Yes, per Prepared rule H. Engine Swaps this is correct. 8/4/2007
07-0056 7/25/2007   SCCA ITR Classification Where are SCCA ITR cars to be classed (Clarification 07-0014) SCCA ITR BMW’s are classed in J Prepared. 7/26/2007
07-0055 6/1/2007   Sponsor Decals and Stickers May racers in all classes replace existing sponsor stickers with die-cut replicas (same size, dimension and design) in the same or alternate colors (if colors are changed, ensuring contrasting colors are used to maintain maximum visibility for the sponsor). Yes, as long as the racer has specific agreement from the sponsor that they approve of the racer’s version of their sticker. The racer should keep a copy of the approval from the sponsor in their logbook in case any questions arise.

BMW Club Racing may require a racer to replace their version of a sticker with the standard sponsor-provided sticker if a letter of approval is not present and a steward determines that the racer-supplied sticker is not consistent with the size, message or visual appeal of the original.

 6/1/2007
07-0054 5/31/2007   Prepared class power steering M3 IP Class Can the Power steering reservoir be upgraded for larger capacity using OEM parts from different model BMW. No, the steering fluid reservoir must remain stock and unmodified. 5/31/2007
07-0053 5/31/2007   Prepared class swapping Starting with a 1992 E36 325is, deciding to take advantage of the motor swap rule, using a US 3.2 M3 engine and going to IP, would it be legal to change out the front steering knuckles, rear trailing arms, steering rack, and transmission to US M3 parts as well, to match equipment that those who have built their IP cars from pre-existing M3’s already have? Furthering this, could you basically swap out any part that would have come from the factory on a US E36 M3? No, components which are not specifically stated as being able to be cannot be changed. 5/31/2007
07-0052 5/31/2007   Ignition in Spec E36 For Spec E36, can the ignition lock cylinder and switch be replaced with a start button and accessory on/off switch? No, ignition components not specifically allowed to be changed as stated in the rules must remain stock and unmodified. 5/31/2007
07-0051 5/31/2007   Roof panels in Modified In reference to a 1999 E46 323 chassis in Mod class, does the following rule allow the replacement of the metal roof panel (with sunroof
opening) with a composite roof panel that replicates the factory metal non-sunroof panel? Or is this rule intended to only allow composite roofs on E46 M3 chassis because of the CSL composite roof?		 Modified class vehicles may run alternate roof panels, either factory or OEM equivalent, which are available for the chassis type (E30, E36, E46, etc). Material must be the same as those options offered from the factory, no alternate materials are allowed. Roof panel material is free in Super Modified. 5/31/2007
07-0050 5/31/2007   Modified Class VIN requirements Do mod class chassis require a VIN or serial number? IE can a body in white which has no factory VIN or serial number be used for vehicle construction? Modified cars required a VIN or serial number (e.g., a BMW Motorsport chassis). Cars built from a body in white (BIW) chassis must provide documentation from the constructor (if professionally built) or the supplier (if purchased directly from a dealer, wholesaler, retailer,
etc) that the chassis was originally constructed by BMW. This documentation must be verifiable otherwise the car will run in Super Modified.		 5/31/2007
07-0049 5/10/2007   Prepared front bumpers The stock class rules read: “Chassis/body, with the exception of spoilers, must be the same material as supplied by the factory.”

“Aftermarket front one-piece bumper/air dam units are allowed provided the original crash bar is maintained OR the assembly is otherwise reinforced to equal strength as the original assembly.”

Would one be allowed to swap a bumper on a prepared car that is aerodynamically advantageous? Are different material bumpers allowed in prepared? (IE fiberglass or carbon fiber) If allowed, this now changes the guidelines for the prepared splitter. Do we measure off the stock bumper or the new bumper with a built in splitter?

 Yes, the entire bumper cover may be swapped even if it has aerodynamic advantages so long as those do not exceed the limits already set forthe based on the stock components. IE, the measurement of the length of the splitter must still be within the limits as defined by that of the stock bumper cover. Bumper cover material may be other than stock. 5/10/2007
07-0048 5/10/2007   Fire system sizing In the club racing rules under Fire Safety the rules state we need a minimum normal capacity of a 2 lb fire extinguisher with a minimum UL rating of 10B:C. My question is If you have a onboard fire system does it have to be UL rated? and does it have to meet a 10B:C rating? What is the minimum rating an on-board fire system must meet? There is no specified rating in the rules for an onboard system. Onboard systems are typically rated by weight or volume, and we’d recommend a minimum 5-lb or 3-liter system. This will be clarified or specified in the 2008 rules. 5/10/2007
07-0047 5/10/2007   Wing mounting in Prepared Spoilers and wings are listed as being free on page 39 of the rules listed on the website. Would mounting the rear wing down to the chassis be allowed in prepared classes? This would require cutting or slotting of the trunk lid to allow this. Along with this would you be allowed to remove the trunk lid shocks to allow easier removal of the steel trunk lid? While spoilers and wings are free, the rules do not allow the modification of the trunk or deck lid by slotting, etc, to allow the wing to be directly connected to the chassis. Further, the wing must mount similarly as a factory wing would mount ( normally bolted to the decklid/trunk lid). If the particular model was never offered from the factory with any kind of wing, the mounting scheme must be bolted directly to the decklid/trunk lid only. 5/10/2007
07-0045 5/10/2007   P/S in Prepared On an E36 in JP, I would like to know if the factory power steering reservoir and rubber lines/hose clamps can be replaced with an aftermarket reservoir, braided steel lines and AN fittings. I would consider this a safety item since it which would eliminate the factory rubber lines and hose clamps, which have a tendency to fail at the power steering cooler return line connection. The current rules do not mention allowing these modifications in Prepared and so they are not allowed. We recommend that these rules be changed for 2008. 5/10/2007
07-0044 5/10/2007   Fuel rail in Prepared Prepared rules state that injectors are free. Is the fuel rail which supplies the injectors considered to be an injector component and therefore free as well? No, the fuel rail is not specifically mentioned in the rules and must therefore remain stock and unmodified. This includes, but is not limited to, the use of AN connections and braided lines which are not allowed. 5/10/2007

07-0040 3/28/2007   Regional Champ points rules For a racer to be eligible for Regional Champion of a particular class, the rules state that a racer must run 3 events but it does not specifically state that those events must be run “in class.” Can a racer be the Regional Champion for a class which he has run less than 3 events in, even if he has run 3 or more events total? The rules imply that the Regional Champion being based on participation in 3 or more events is “in class.” A racer must run in class for 3 or more events to be eligible for Regional Champion in a particular class. 3/28/2007
07-0039 3/28/2007   Dry break fuel filers in Spec E36 and Prepared [SpecE36 and Prepared Classes] Is a dry break fuel filler allowed while retaining the stock fill neck, and tank? No, dry break and/or quick fill fuel set ups are not mentioned in the rules and are therefore not allowed. 3/28/2007
07-0038 3/28/2007   Mod class cage tubes For a Mod class cage, can reinforcing tubes (such as tubes running to subframe mounting points) be made from 1″ tubing or must they be made from the size diameter tubing as the rest of the cage? The rules seem a bit unclear/contradictory on this.

Appendix A.16.A reads:
“Any number of additional reinforcing bars/braces are permitted within the structure of the cage provided that they meet all the installation, weld quality, tube diameter/material/bend specifications as required.”

Appendix A.17.C reads:
“Only required roll cage tubes must meet these requirements. Tubes which obviously do not serve as a required tube may be of different specification.”

 The “diameter/material/bend specifications as required” phrase in A.17.C refers to mandatory/required parts of the roll cage (“as required”). Other
(non-required) tubes may be different size. In other words, the minimal parts required to make a full legal roll cage must meet the required diameter/material/bend specifications. Other tubes are free, subject to the general safety requirements. We will clarify this wording in the 2008 rules.		 3/28/2007
07-0037 3/28/2007   Lexan in Prepared Prepared rules, it states that door glass can be removed but is it referring to the front doors only? this seems like a good idea from a safety point of view to get all side glass out and lexan is not that expensive. In prepared can all door or side glass can be removed in favor of Lexan? Rear doors are not allowed to be gutted (IE removal of internal bits including, but no limited to, glass, motors, lift mechanisms, etc), only front. Lexan is not allowed. 3/28/2007

 Yes, the connection between the plenum and the throttle body is free. 3/28/2007
07-0034 3/26/2007   Spec E36 roll cage mounting In Spec E36, Rule 8A states: The roll cage must meet the

rear subframe are not permitted.If the rear braces end at a plate which happens to be positioned on the body
above the point where the rear subframe is attached to the body, is this
considered a violation of rule 8.A. stated above?		 Stock, Prepared, and SpecE36 classes are limited to plate attachements
for mounting points so there is no direct way to tie into suspension pick ups.
Location of plates is not limited other than by any other stipulations
(including mounting a plate above a pick up point – which is allowed) other
than generaly safety.		 3/26/2007
07-0033 3/26/2007   Fuel rails in Prepared. Prepared rules state that injectors are free. Is the fuel rail which supplies the injectors considered to be an injector component and therefore free as well. No. The fuel rail is not listed as free in the rules and is therefore not free. 3/26/2007

rules will be clarified to remove or explain “comparable.”		 2/28/2007
07-0028 2/25/2007   Flaring Fenders in Prepared Are we allowed to flare the fenders to fit tires for prepared class? No. Since there is no Prepared-specific fender shaping rule, we fallback to the
Stock rules which do not allow any flaring.		 2/25/2007
07-0027 2/25/2007   Foglight Blanking Plates In Stock and Prepared, is it legal to remove or replace foglights with

blanking plates to avoid glass on the track, even if the opening is not used to duct air to brakes or intake?

 Yes. Stock rule 7.C clearly implies this although it’s not clear enough and the wording should be improved to specifically allow blanking plates. 2/25/2007
07-0026 2/25/2007   Dry Sump Tanks May the dry sump oil storage tank (in a Modified class car) be placed within

07-0018 2/8/2007   Oil pump improvements. Can the oil pump sprocket, shaft and their attachment be altered for reliability in Spec E36? Specifically, can a vendor’s kit which replaces the oil pump shaft and sprocket with a slightly elongated shaft and a splined shaft/sprocket connect be used? Or, can I safety-wire it? In all classes (including Spec E36) the oil pump shaft and sprocket may be altered or replaced for reliability as long as improved reliability is the only purpose and result of the alteration. The bolt may be safety-wired, or the shaft and sprocket may be replaced with aftermarket units that have improved attachments (eg, splined). The sprocket must remain the same size and have the same number of teeth as the original part. 2/8/2007
07-0017 2/8/2007   Wiring removal in JP Question: In the Prepared Class rules, Section 7. Body/Chassis/Interior,
Letter G. states: Wiring to components which may be removed according to the rules may also be removed. Fuses and relays for unused components may be
removed.

Therefore, can all wires and associated switches, fuses, fan connectors and relays of a component also be removed in their entirety, back-to and
including the wires running to the fuse box?

For example: As per Letter H. All heating and air conditioning components may be removed, does this allow for all wires, switches, fan connectors, fuses and relays associated with the heating and air conditioning components back-to and including the fuse box feeds to be removed from the chassis?

 No clarification required. 2/8/2007

06-0028 5/3/2006   Mass air meter in Prepared Class cars Regarding the type of MAM (Mass Air Meter) allowed in Prepared class [specifically OBDII E36 M3’s – ’96+], section 1.A.1. Currently, this rule allows only BMW MAMs, but elsewhere in the rules, a full change to an OBD I electronics system is allowed.

The part that should be allowed, but currently is not under this rule, is the MAM from a Porsche 996. This is visually identical to the Euro M3 HFM used on E36 M3 cars [OBDI], except for part number – and it plugs directly into the OBD II harness,

 The stated rules in BMW CCA Club Racing rules V11.2, Prepared Classes, 1. Engine A. Intake System, 4., page 30 are clear on which MAM’s are allowed specifically. This request constitutes a rules change request, not a clarification and thus the Porsche, or any other NON BMW MAM, is not allowed.

Window glass and window actuator mechanism may be altered or removed. However, any door adjacent to a seat equipped with seat belts or harness must be capable of being opened from both inside and outside the car.”

Can the rear door panels be removed/replaced as the fronts? Do the rear door panels

 Rear doors are passenger doors and therefore the panels may be removed, same as the fronts. As with the front panels, if they are removed an aluminum or comparable material panel must be put in its place. Minimum weight of the vehicle must still be met as per the rules.

Wings provide aerodynamic effect by use of an airfoil section.” This rule does not appear to require the wing to be attached to the rear decklid. Stock Class Rule 7.E.1.e goes on to say that “”wing” will be used to refer to aerodynamic devices above the trunk line at the rear of the car.” Mod rules later restrict mod wings with this wording in Mod Class R “Wings are free, provided they do not exceed maximum body width, are no higher than the roofline, and extend no further than 16″ behind the rear bumper.” Velocity generators that meet these requirements are allowed in modified class.

But I believe it is an 8mm wire and the stock is 7mm. Do I need to replace these back with a stock set? As the stock class rules state, “…Spark plug wires must be OEM or an exact aftermarket replacement.” Therefore a wire that is of a different diameter than stock is not allowed.

06-0013 1/23/2006   Stock class motor built with aftermarket pistons I have a rebuilt S-14 motor in Stock Class. The motor was rebuilt 8/05 with CP pistons having an overbore of .020″. Do I have to run the +50 sticker on the windshield for the ’06 season. Does that mean new pistons for ’07? As the rules state in Stock Classes, 1. Engine: “I. All pistons, including aftermarket replacements, must be factory replacement spec and match factory dome, dish, valve relief depth, ring groove placement, weight and wrist pin height; compression must meet factory replacement specifications. The maximum allowable overbore is limited to the largest available factory replacement piston, not to exceed .020 inch. Engines which were built before the 2006 season using pistons that are larger than the maximum factory replacement specifications, but still smaller than or equal to the 0.020” absolute maximum, may be run in Stock class for the 2006 season only, with the following requirements: 1. The logbook of the car must contain a signed and dated statement on the first unused event page by the car owner that the engine contains these pistons. 2. The car must carry a penalty weight of 50 lbs (above that minimum stock class weight required by the rules). This additional weight must be indicated with a “+50” decal on the lower right side of the windshield in white letters 3” high.” Therefore, yes, it is required to run an additional 50lbs of ballast (secured as per the rules) and additionally the appropriate “+50” indication on the lower right side of the front windshield. The rules change proposal period for 2007 rules is not open yet therefore there is no guarantee that there will or will not be a change for 2007.

“Effective April 1, 2006, all racers must use a Head and Neck Restraint meeting standards SFI 38.1 or FIA 8858-2002. The SFI standard can be found at: http://www.sfifoundation.com/manuf.html#38.1. ” The Isaac device does not have an SFI 38.1 certification. While their website claims that their device “meets or exceeds the performance requirements of SFI Specification 38.1” it has not actually passed the tests, and is therefore not currently SFI 38.1 certified. Once this device (or any other device, for that matter) is actually certified by the SFI as meeting 38.1 it is automatically approved for BMW Club Racing.
