There is a pic floating around here of a fox with HUGE wheels in all four corners. But it has those flaired out fender/quarter kits on it. It was a road racing car.
IF you try it. 96-04 spindles are a must, and you will need extended lugs and big spacers. STock struts are a must, because coil overs give you less clearance with big tires and wheels.
One alternative is to install 94-04 LCA's. The ball joint is 1-1/2" further out, giving you more clearance, but then the wheels will stick out way past the fenders, looking really stupid.
