A. Definition
The B-Spec and C-Spec CATEGORY categories shall be considered primarily as a form for the membership to race street stock
automobiles. Eligibility of cars may be discontinued at any time, for any reason other than competitive stature. The burden of
proof lies upon any participant seeking action against another participant.
NOTE: A Shop/Service Manual or its equivalent for the specific make, model, and year of automobile is required to be in the
possession of each entrant. Manufacturer Shop/Service Manuals may come in the form of printed material, microfiche, CD, DVD,
and/or Internet access to manufacturer website databases. It is the responsibility of the competitor to provide the electronic
device capable of accessing the data for compliance verification. If Manufacturer Shop/Service Manuals are not available, then
the competitor shall have a copy of the official SCCA® Vehicle Technical Sheet (VTS) with them at every event and shall present it
for reference when officially requested. The manual is intended to aid SCCA® Technical Scrutineers in identifying parts and the
configuration of the automobile. Overhaul procedures that in the slightest way would increase performance are not to be
utilized (e.g., milled heads/blocks, porting, etc.). Blueprinting and balancing are inconsistent with the philosophy of this class and
are not permitted.
B. Automobile Eligibility
Only those cars listed on spec lines are eligible to compete. Cars classified will be approved by EPA and DOT for sale in the
United States and by Environment Canada for sale in Canada. They shall be models available to the general public for purchase.
Additions and deletions of automobiles shall be at the discretion of the SCCA®. The vehicle identification number (VIN) shall
correspond with the model automobile classified. At least one VIN plate or stamping shall remain in place on the dashboard or
chassis that corresponds with the model automobile classified.
C. Classification
Classifications of automobiles eligible for competition will be reviewed on an annual basis and will be effective as of January 1st.

Heater cores, and hoses, must remain except duct work under seats. Duct work behind the dash may be trimmed but not
removed to allow for roll cage installation.
35. Maximum 3.5 degrees negative camber is allowed on front and rear suspensions. Strut suspensions may adjust camber by
the use of eccentric bolts (crash bolts) at the strut-to-spindle, slotted strut mounting holes at the spindle, and/or by use of any
slotted camber only adjuster plate at the top of the strut mounting plate. If upper strut slotted plates are used, they shall be
located on existing chassis structure and may not serve as reinforcement for that structure. Modifications to the top of the strut
tower may be made to allow for camber adjustment only. Modifications to the existing holes must only be moved straight
inboard even if the existing slots would translate the top of the strut rearward. On other forms of suspension, camber
adjustment may be achieved by the use of shims and/or eccentric bolts (crash bolts).
36. Suspension: competitors may use the OEM suspension, the specific suspension kit approved on the spec line or any B14
Bilstein shock or strut with no modifications except as required for mounting or to achieve allowed camber. Any camber plate
may be used, but may not alter caster. Caster shall be within factory specification. Any part required to adapt the B14’s to the
car must be submitted for approval by the CRB and added to the individual spec line. Any spring, including ‘helper’ or ‘tender’
springs, up to a maximum spring rate of 500 pounds may be used. Helper springs made of thin flat wire that are designed to take
up the gap between the main spring and shock/strut at full travel are allowed. Tender springs are not allowed. Springs are
allowed to be strapped or zip tied to the body. The purpose of the strap should be to keep the spring in place when the axle goes
into rebound. The strap can serve no other function. Bump stops may be deleted but cannot be modified or substituted and
shall serve no other purpose. Adjustable sway bar end links may be used on all cars. Sway bars may be disconnected and
removed.
If a manufacture does not offer an upgrade, a competitor may submit a shock and spring package for approval by the CRB. At the
time of approval, that kit will become the standard for that make and model until the manufacture submits a factory supported
kit.
The competitor supplied kits needs to be comprised of the following:
• Any non-adjustable shock absorber intended for the specific make model and year car is allowed. The shock absorber must be
installed in the original mounting locations. Remote shocks are not permitted. Threaded shock bodies or adjusters may be used.
• Any spring up to a maximum spring rate of 500 pounds may be used with the OEM suspension, the
manufacturer’s upgraded suspension kit, or the Bilstein B14 suspension kit.
37. ECU/PCM: OEM ECU/PCMs is required. Alternate engine calibrations are allowed. The car may meet federal emission
standards, but shall provide OBD II compliant data to the data link connector. Manufacturers may provide a stability control
override procedure or module.
38. B Spec and C-Spec front and rear toe settings are free. Rear toe adjustments may be achieved by the use of shims.
39. Fenders and wheel openings shall remain unmodified. It is permitted to roll under or flatten any interior lip on the wheel
opening for tire clearance. Cars with plastic/composite fenders may remove any interior wheel opening lip, but the resulting
material edge shall be no thinner than the basic fender material thickness. Non metallic inner fender liners may be removed.
40. An oil catch can is permitted.
41. Optional Hood Pins may be added to supplement the original hood latch system. All parts of the original hood latch system
must remain in the car.
42. Brake ducts are permitted, but they must serve no other purpose. Duct openings may be created by the removal of the fog
lights. Alternatively, duct openings may be created by opening 2 sections up to 14.5 square inches each of stock false grills
originally located in the front fascia, or radiator shroud, but in this case while fog lamps may be removed. Fog light holes must
be completely covered. The stock headlamp location is not permitted for brake ducting.
43. Automatic and cvt transmissions versions of all legal cars are legal for competition in B-Spec and C-Spec meeting their spec
line. Models with OEM paddle shifters are acceptable. Auxiliary transmission coolers may be approved on a case by case basis.
Part numbers must be submitted and added to the cars spec line.
44. Auxiliary transmission coolers may be approved on a case by case basis. Part numbers must be submitted and added to the
cars spec line.
45. Restrictor – BS B-Spec and C-Spec cars whose spec line require a restrictor will follow the definition of a Flat Plate Restrictor
(FPR) outlined in Appendix F with only one exception, B-Spec and C-Spec requires the thickness of the Restrictor to be 0.050” to
0.079.
46. All B-Spec and C-Spec cars in post-race impound at all Majors and Super Tour races shall open their hoods and
hatches/trunks for the purpose of visual inspection by other competitors. Competitors may thereafter initiate a protest as
permitted under the GCR.”

are to such level; the BoP is not a handicap program. And, while the class is named “BSPEC”, it is not a spec class as is FE2 or SRF3.
The more experienced mechanics and drivers will certainly have an advantage over those who only race a few times per season.
Anecdotal observations do not serve the SCCA in working towards a proper BoP, yet that is the type of information most commonly
provided in support of a requested change. Hard data and experience are what drive change to the BoP.
Despite what we believe to be an excellent BoP for this class, there is always room for improvement. The BSPEC Advisory
Committee has recently been charged with the considerable task of classifying cars and refining the technical specifications for
the new T5/CSPEC class and, as a result, does not have sufficient time or resources to address the immediate demands for BoP
adjustments in BSPEC. As a result, veteran CRB members Peter Keane, Tom Start, and Sam Henry have poured through BSPEC
data reports from events over the past eighteen (18) months and have recommended to the CRB the following changes which
were approved during its most recent meeting. These changes will be effective beginning 5/1/2023 for positive adjustments and
6/1/2023 for negative adjustments. Data will be gathered as possible with a focus on continued improvement. Comments and
suggestions regarding same should be forwarded through the official letter system. Your continuing support of BSPEC and SCCA
is greatly appreciated.
