Saleen Wheels On Fox

I wouldn't buy the 10's in the rear. A fox will not easily fit a tire meant for a 10 inch rim, so you will be causing clearance issues for no reason.

I don't know the offsets of replicas that fit, but you shouldn't need spindles if you are doing a basic fox style 5 lug conversion.

If you get the offset right, i probably wouldn't go past a 275 in the rear (i find that a 265 fits better) or a 245 in the front.
And so you understand how wide that is, these tires will fit on an 8.5 rim.

I'm running the 18x9's on all fours. 94-95 spindles up front stock length in the back on steeda springs. 255/35 front tires and 275/35 rears. No rubbing at all rear fenders are rolled and the car is a 92 so it has extra clearance up front.
