Super Touring Throttle Body Clarification
#37581 from Adam Sargis · Recommended to the Board · Minutes (2025-02 Fastrack)
In GCR, Section 9.1.4.G.8, change as follows:
"(Effective 4/1/2025) Cars produced with an electronic throttle body may use the OEM electronic throttle body. The OEM
electronic throttle body may be converted to manual actuation and the actuation cam on a manual throttle body may be
changed to alter the opening/closing rate of the butterfly. Alternately actuated throttle bodies may be considered on a case by
case basis. Vehicle/engine combinations with manual OEM throttle bodies may be converted to an OEM electronic throttle body
of the same inner diameter as the original OEM throttle body. An 1" thick adapter plate may be used to facilitate mounting."
