Does anyone autocross their ITB car with a welded diff? I know the car can run in SP in ITB specs (maybe not that competitive?) The reason I am wondering is that I am finishing an ITB A2 GTI this fall and I will autoX, HPDE, and drivers school before bashing your fenders. Who do you get to weld your diffs, do you do it yourselves, how do you do it properly. Cheers
