I am ready to order a set of 15 X 10 prostars for the back of my car. Just wondering what backspacing most people are running. I would like to tuck as much as I can under the fender. The car does have a solid rear-end if that matters. Im gonna have a 28 X 10 tire. Also I think Ive read that im gonna need some kinda spacer to run the 15 X 3 1/2 fronts.

I have 15x10 w/6.5BS and run a 1/2" spacer on the rears. Up front I have the 15x3 1/2 with 1.75BS and need to run a 1" billet spacer to clear the brakes. You will have to get longer studs installed and thru lug nuts for when you run your street wheels.

DO I need longer studs on the front and back?

I have 15x10's on the rear with 5.5 inch backspacing. For the fronts you will need a 1 inch spacer.

Depends on the SRA year you have under it. Mines a 99-04 unit and with 15X10's on a 5.5in backspace a 28X10.5-15 ET Drag slick it will rub on the right side when I launch, even with the fender lip rolled. Hence the 6.5in backspace for me..
