Allowing F4 into FC to Increase Involvement, and Safety.
#36576 from Jacques Coury · Not recommended · Minutes (2024-10 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change. The F4 cars use a carbon fiber chassis, which
is not permitted in the FC class. However, both the FIA Certified 1st Gen Ligier JS F4 and 2nd Gen Ligier JS F422 are currently
classified in the FX class. Please see the GCR for the specifications and restrictions.
