im getting ready to get new rims and rubber for the car, it's a 85 modreal with the 2 extra shocks removed for more room, what is the correct back spacing in the rear for a 15x8-9 with out stick out the fender and the front for 15x3.5 or 5

 

if i remember right it is 4 on a 8" wheel and go with the 3.5's up front
