Proposal to Revise Spring Rule for Mazda RX-8
#37335 from Raymond Blethen · No action required · Minutes (2025-02 Fastrack)
Thank you for your letter. A maximum spring rate has been the standard spring allowance method for the touring classes (as
well as B-spec and C-spec) for years. The variability in the rule allows people to make adjustments to suit their needs, making
cars more competitive, more consistent and appealing.
