Gap is the driver's best lap in a session against the fastest lap in their class in that same session (zero is fastest in class), shown as time lost and as a share of the lap, so conditions cancel out and tracks can be compared. Typical is the median session.

Letters to Fastrack
GTX Ligier P3 LS Swap
#38164 from Bart Wolf · Rule change · TB 25-06 (2025-06 Fastrack)

#38097 from Bart Wolf · Not recommended · Minutes (2025-05 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend these changes. The CRB had sufficient AiM data for a
wide variety of P1 and P2 platforms as of 2024 and did not need to collect additional data in 2024 because the specifications of
the platforms had not changed since the previous data was collected. Further, a majority of the P2 platforms fit readily into spec
lines in the existing P1 engine table, and adjustments were made for P2 platforms that did not. For example, in P2 the tube-
frame Group CN car was limited to a stock Honda K20A engine using a stock single throttle body with a 50mm flat plate intake
restrictor at 1,500 lbs. minimum weight, and in the Prototype class that car is now permitted to use an internally modified K20A
with unrestricted individual throttle bodies at the same minimum weight. The CRB intends to obtain AiM data from various
platforms in the Prototype class during the season but has no plans to make BoP changes in the class prior to the June Sprints.

#35836 from Bart Wolf · Not recommended · Minutes (2024-05 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change. In the P2 class, Balance of Performance
(BoP) adjustments are not used to equalize top-speed performance, which is heavily affected by the balance of aerodynamic
efficiency versus the downforce package chosen by the driver. If top-speed performance were a basis for BoP adjustment in P2,
no change would be needed: race performance data obtained in several recent events from the subject CN platform and various
cars using motorcycle engine-based platforms does not indicate that the CN platform has a top-speed performance
disadvantage. In P2, the criterion for a BoP adjustment is limited to the analysis of a car's longitudinal acceleration rate in a
speed range before aerodynamic drag has a significant effect—typically between 60 and 100 mph. The data does not
indicate that the CN platform has a performance disadvantage in its acceleration rate, so no justification exists for changing the

size of the CN platform's flat plate intake restrictor at this time.
