SCCA has a basic "catch-all" philosophy for such situations . . . if the rules for your class do not specifically permit doing something (and the class is not built on a lower-prep class that does permit doing it) it's not allowed.I also changed the rear gear from 2.73 to 3.73 but don't see mention in the STU rules for gear changes.
