In MOST places a trans brake is considered "electronics". Most places that run typical bracket classes.. Street, Pro and Super Pro, the electronics are reserved for the Super Pro cars. Pro is Footbrake, no electronics. And Street.. is street tires.. no electronics.. All the places I have ran have been that way. It sounds like you'll be having to Footbrake this race.
They say what goes up must come down but I ain't reached my cruising altitude.
Take a look at what I did but can you imagine what I'm about to do.
