I'm not building it for drift use but the modified uprights I'm using allow for mahoosive lock as they're designed for drifting primarily. Main reason I want them is the 50mm raised spindles.
Driftworks have not long finished building an ae86 V8 drift car which has a very similar wheelbase. It has a lot of money thrown at it obviously but he's commented that it is quite wild but once tamed should be hugely competitive. Build thread here -
