couple have been done for drifting in the uk and did see one in some some amateur sports class on the telly the other week. It was pretty standard bar a few decals. He'd only had a week so hadn't had much time to do any work on it.
Are you intending to do anything performance wise. If you do you'll need to do some research. Piggy back ECU for starters plus if going over 400bhp they you'll need upgraded internals.
