Ceramic Transmission Upgrades
#34797 from Donnie Isley · No action required · Minutes (2023-10 Fastrack)
Thank you for your letter. GCR section 9.1.1.C.1.B states that "Mass-produced, direct replacement components may be
substituted for the following as long as they are of the same material and dimensionally identical to the original VW components
they replace," and that section further states that this pertains to "VW transmission components" and "Rear axle components."
As such, transmission/transaxle components that are made using ceramic materials (or any other material not used in the
original component), either in part or whole, are not permitted to be used in the FV class. Likewise, any transmission or rear axle
components not dimensionally identical to the original VW component are not permitted to be used in the FV class.
