If I install 94/95 spindles and brakes on a fox along with 5 lug fox length axles will these wheels/tire combination fit? will the rear not stick out and be flush to the fender well? if anyone can help me with this situation i would greatly appreciate it.

If you go with 1994 up brakes it gives you a much larger selection of wheels you can run on a fox body. However, the 10.5 on the back you will still have some clearance issues and have to make some modifications such as removing the quad shock , rolling the fender lip and beating the inside of the fender well. So it can be done but not without some modification.

The rear is a 10" not 10.5 sorry. So I guess with just with minor modification (quadshock removal, a little banging here and there) the 10 with the 315 wont look bad on the coupe.
