BS for a 2.5" shortened each side 12 bolt??? I am strongly looking at a Strange 12 bolt that has been shortened 2.5" on each side but im not sure which backspacing to run? The car will have stock (grinded) LS1 brakes with a small spacer to clear. Also I would like to stick with my Prostars. I have the 7.5 BS ones now so I could sell them and get the correct ones. Would 5.5" BS work??? I want them to be tucked and not sticking out as the car will be lowered and fenders rolled.
Thanks!
Thanks!

If you have a housing that is 5 inches narrower... you will need to decrease your backspace by 2.5 inches per side. Meaning... that if you have 7.5 inches of backspace right now, you will need 5 inches of backspace to run that housing and be the same.
As for 5.5 inches... its your call. You should get under the car and take a look to see if that is even a possibility. I think it is... but I can not say for certain without looking myself.
How much room do you have with your current set-up ??

I have a pair of new ProStar XP 16 x 8 wheels in stock, that stock way out on a stock rear. I'll have to check on their backspacing, but I'll bet they are what you need. Bob

I have mine narrowed 2 inches a side, I went with 15x10 with 5 inch BS, I know on my moser 9 inch my brakes are really close to the lower control arm relocation brackets, I even had to cut some of it out and weld peices in there so the brakes would clear, just something for you to think about.

With a 10" wheel it'll set exactly where mine sit now. I'm running the stock rear with a 7.5" backspacing and have the 325/50/15 mt dr's on them. I'm not lowered, and they are very close and took work to fit, but your going to be on a narrower tire.
Yours will be 28.1, 11.7 sidewall, 10.0 tread width vs my 28, 13 sidewall, 11 tread width, so they should fit fine. You might have to run a small spacer to bring them out slightly, but other than that they should be able to fit..
I've also got a 12 bolt that is narrowed 2.5" per side and I'm up in the air on going with 15x10 with a 5.5" bs prostar, or switch to telstars and run a 15x10 with a 5" bs. The prostar would sit in .5" but I could bring it back out a little with a spacer if I have to, I'm already very close to my lca and don't want to have to purchase the offset ones just yet. I do also plan on lowering the car.
