No Assisted Shifting for FIA Group CN Cars in P2
#28072 from GREG GYANN · Not recommended · Minutes (2020-03 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change. The Group CN spec
line divides equipment into two categories: (1) certain listed components of the original FIA
homologation that competitors are required to use; and (2) certain listed components permitted by the
premier V de V Endurance Series that competitors are allowed to use. The shifting system is not one of
the original FIA-homologated components that competitors are required to use, but assisted shifting is
one of the components permitted by the V de V Endurance Series that competitors are allowed to use.
The intent of the spec line is to allow CN cars to run in P2 as they run in the V de V Endurance Series, and
to control the cars’ performance in P2 by the use of an appropriately-sized flat plate intake restrictor, as

determined by rate-of-acceleration data obtained by the SCCA. The Club Racing Board will continue to
monitor class performance and will make appropriate, data-based adjustments as necessary.
