#33866 from Frank Schwartz · Rule change · TB 23-03 (2023-03 Fastrack)
In B-Spec Category Specifications, GCR Section 9.1.10.E.36., change as follows:
"Suspension: competitors may use the OEM suspension, the specific suspension kit approved on the spec line or any B14 Bilstein
shock or strut with no modifications except as required for mounting or to achieve allowed camber. Any camber plate may be
used, but may not alter caster. Caster shall be within factory specification. Any part required to adapt the B14’s to the car must
be submitted for approval by the CRB and added to the individual spec line. Any spring, including ‘helper’ or ‘tender’ springs, up
to a maximum spring rate of 500 pounds may be used. Helper springs made of thin flat wire that are designed to take up the gap
between the main spring and shock/strut at full travel are allowed. Tender springs are not allowed. Spring are allowed to be
strapped or zip tied to the body. The purpose of the strap should be to keep the spring in place when the axle goes into rebound.

The strap can serve no other function. Bump stops may be deleted but cannot be modified or substituted and shall serve no
other purpose. Adjustable sway bar end links may be used on all cars. Sway bars may be disconnected and removed."
