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.

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.
