Events

This track has been raced on 4 configurations (The Circuit, 2.57 mi; 2.92 mi; 1.83 mi; 3.02 mi). Laps on different configurations are not comparable, so only events on the 2.57 mile layout are shown; switch above to see the others.

One session is left out because the timing does not look like full laps: Cal Club 2023 Qualifying #2.

One run is left out as not that car's own laps (far quicker than the car managed in any other session and than anyone else in its class all week; usually a swapped transponder): Thomas Lepper in Cal Club 2026 Grp 1 EP FP HP B-Spec Race 1 (1:42.146; the car's best in any other session was 2:12.311 and the rest of the class's best all week 2:09.353).

One row per driver and car (a driver who changed cars has a row for each). Each cell is that driver's best in that car across the selected events, with the session it was set in. Best 5-lap stint is the mean of the driver's quickest five consecutive race laps, and consistency is how far their median race lap sat behind their best in that race (small is a driver who does it every lap); both come from the race with the best stint. The fastest in each column is purple, and a car whose best lap is more than 115% of the fastest in its class is greyed (marked ">115%" beside the driver) and left out of the colour scale. Click a column to sort, a row to highlight it. Theoretical lap is the sum of the best sectors, whichever laps they came from, and never slower than the best lap (where a car's fastest laps were recorded without sector times, its best lap is used). The 115% mark is about the car's best lap only: a car whose best lap is within 115% of the fastest in its class is never marked. Greyed sectors with no theoretical lap mean the sector times on file do not add up to a believable lap. Letters refer to the events above; Q is qualifying, R a race.

Sectors

Sectors are numbered in lap order from start/finish, whatever each event's timing called them; the loop names are SCCA timing's.

following items: TIRE SIZES, RIM WIDTHS, SPRINGS, ANTI-ROLL BAR(S), and PERFORMANCE EQUIPMENT. In the case of the
foregoing exceptions, the B-Spec these Competition Rules will have priority.
These specifications reflect the best information available at the time of publication. Any error found in
this edition will be updated when reliable specifications are available from the manufacturer/manufacturer
distributor or other sources recognized by SCCA®, Inc.
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.
D. Technical and Safety Items
The following represent the only safety items and modifications permitted and required on automobiles involved in B Spec and
C-Spec competition. Cars must meet comply with the GCR. The addition of safety items not specifically listed is not permitted.

manner to provide protection in the event the driver’s door opens. Rear windows shall be run in the closed (up) position.
5. Passive restraint systems shall be deactivated.*
6. Air bag systems shall be disarmed and may be removed.* If so equipped, the rolling door lock mechanism may be deactivated
by unplugging the components.

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

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

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.

The popularity of BSPEC has brought heightened attention to the Balance of Performance (BoP). Given the wide diversity of
eligible cars and their designs, driving ability, car preparation/tuning levels, and other variables outside of SCCA’s control, the BoP
in this class has been remarkably close. As compared to IMSA’s job of balancing cars which are all professionally prepared, driven,
and highly instrumented, the job of our advisory committees and CRB is considerably more difficult. There are most certainly
outliers and cars which are superior under certain conditions, but in the absence of BoP regulations which vary from track to track
a perfect balance every weekend is not to be expected. The BoP is set by SCCA for what is perceived to be the ultimate tune and
best driver in a given car across the entire racing season and over as many tracks as can be reasonably sampled. If a car is not
prepared, tuned, and driven to its ultimate capability we cannot expect that it will be on par with cars of other manufacture which

Show 52 more lines

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.
