Begin Tracking of Non-Ferrous Brakes in P1
#35716 from Perry Richardson · Not recommended · Minutes (2024-04 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change. P1 is a development class in which a majority
of respondents to a 2023 survey favored retaining non-ferrous/carbon-carbon brake systems, and penalizing development
within the rules would be contrary to the class philosophy. Although Balance of Performance (BoP) adjustments are used to
permit different platforms to race together in the same class, the criterion for a BoP adjustment is limited to the analysis of a
car's acceleration rate in a speed range before aerodynamic drag has a significant effect — typically between 60 and 100 mph.
BoP adjustments are not used to equalize lap-time performance or ensure overall competitiveness, and the CRB does not adjust
power or minimum weight based on the use of different brake systems, aerodynamic configurations, or chassis setups. BoP
adjustments based on the type of brake system used would be particularly infeasable, given that driver technique during braking

is highly variable, unlike driver technique under full-throttle acceleration.
