No mapRunoffs 2020

This track has been raced on 2 configurations (Scoring Sidebar Race, 4.05 mi; 4.01 mi). Laps on different configurations are not comparable, so only events on the 4.05 mile layout are shown; switch above to see the others.

Sectors are not comparable across all of these events. Sector times and the theoretical lap use Runoffs 2025, Runoffs 2026 only. Runoffs 2020 (different number of sectors), Runoffs 2024 (different number of sectors) count towards whole-lap times and trap speed only.

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): Kent Carter in Runoffs 2024 Run 1 EP, FP GTL, HP, B-Spec, STL, T3, T4 Sat (2:35.977; the car's best in any other session was 2:54.190 and the rest of the class's best all week 2:51.889).

10 laps are left out as timing errors (far too short to be a lap of this track). The rest of those sessions, sectors included, is used.

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

S1 SF → I4AT 1.26 mi
S2 I4AT → I11 1.65 mi
S3 I11 → I13AB 0.57 mi
S4 I13AB → SF 0.57 mi
SF Spd SF → SFT 0.02 mi
Spd I4AT → I4A 0.02 mi

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

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

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

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.

2026-05-01 B-Spec Race Memo RM 26-01 B-Spec Mini Cooper Weight Adjustments with OEM

#40070 from B-Spec/C-Spec Committee · Rule change · TB 26-05 (2026-05 Fastrack)

fasterB-Spec Mini Cooper variants lose 75 lbs with OEM catalyst, to 2600; header config at 2675.

The BSAC reviewed historical data, results, and past BOP of this platform in arriving at this decision. It is our desire to see MINIs
with the OEM manifold/approved Walker brand manifold competing at events. The BSAC will monitor the performance results
of these changes closely at HST events and the Runoffs over the coming months. Should data show that these cars are outside of
the desired performance window (I.E. too fast OR too slow) at their updated minimum weight, further BOP adjustments will be
made to ensure continued competitive parity. Data from a minimum of three drivers/vehicles from Majors or Super Tour
weekends will be evaluated before any further BOP adjustments are made. No further adjustments will be made to the header
configuration before its expiration on 1/1/27.
