Description
E8x/E9x is very difficult to make a rallycar due FIA regulations insist a lot smaller wheel than to what the knuckles are designed to have in STD. When using 15″ wheel you need this kit + TCA kit from us. But even then you have to modify the knuckle, expecially if you use M-version of knuckle as this car had.
Bumpsteer mean toe change when tire moves in suspension up and down. On streetcars you usually can measure 20-40mm of toe change in full stroke. In racing you usually want to minimize the change. Without bumpsteer tierodjoints is very difficult.
