4-Bolt Disc Brakes in FV
#30080 from Matt Clark · Not recommended · Minutes (2021-02 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend restricting the weight and material of the hub assembly
at this time. The disc brake rule permits the use of any hub assembly as long as it can be fitted with a wheel allowed by the
Formula Vee rules. The rule already allows the use of two-piston calipers and two-piece rear brakes. Please see GCR section
9.1.1.C.4.D. The type of wheel used does not determine the disc brake components permitted. Please see the response to letter
#28955, November 2020 Board of Directors Minutes.
