86 cutlass
 

largest wheels and what back spacing can be ran on 81-88 g-body with no rubbing at any time.

15" wheels i ran a 255-65-15 fits nice was on a set of weld rod lites.

depends on the tire.. 265 and 285, 35-40 18..., if you do a frame notch to the seam you could fit 295-325´s carefull measuring is the key...


you need about 5.6-5.9 inches of total backspacing (including the tire) and a hair more with disc brakes...
