10 inch wheel with 4.5 back spacing question.

[79olds1985]

does any one have a 15x10 rim with 4.5 backspacing on their car? If so could you tell me how much on each side for the rear end did you narrow it. Im putting it on a 83 cutlass with a frame notched to the seem and wheel lip rolled. Piston on here tells me ( the guy i got the rims from) that i should go with 1-2 inch narrower on the rear altho i trust his word just trying to see if some one can give me a definate measurement from first hand experience. Thanks

The car in my sig had 15X10 with 5.5 bs and only notched to the seam I'd sAy 1-1.5"

I got the Street Lite in that configuration and it will not work. The spacing needs to be 5 inch but Billiet Spec only make half sizes. The outer was dead even with the fender lip and mine was rolled. With frame notched and lip rolled it needs to be 5 inches on the back spacing and a 275/60/15 tire will fit with no issues.
