My 86 had a flip kit in the rear
Rims are WELD prostars 15X10 with I believe 4.5" BS
TIRES - MT et streets 325/60/15
Only thing i did for extra clearance was pull the rear tires off and using a cutoff wheel I cut the inner support on the wheel well. Then notched the fender lip and rolled it.
this is an old pic but I wanted to show the side of it and how it looks
I personally loved the rake it gave me. And here soon I will be ordering some 15x6 prostars for the front in 5x4.75 lug pattern and doing a disc conversion up front to change my lug pattern
