Ok I'm borrowing a freinds Peo Stars on my 02 Z28. His wheel are from a 93 Z28.
He grounded the hell out of my front and rear calipers but the rears won't fit when tighten all the way down.
What back spacing do i need for 15x3.5 and 15x8 they I don't need spacers for the rears.. Front has spacers. But what do all the LS1 guys run for weld pro stars.

5.5 inch backspacing for the rears. from what i've heard the rear need spacers as well. not sure about the fronts though. do you still have the stock wheel studs?

You should not need spacers on with a 15x8 on a 5.5 BS if you grind enough. I run 15x10s on a 7.5BS. You rear calipers should look something like this when done.

Fronts have stock wheel studs and rear have 1/2X20 extended studs

I didn't think so but I could be wrong. All 4th gens use a 32" axles so the wheels should be in the same area. If you have to wheels at your house just take a tape and measure the BS to double check. You really should get some longer studs for the front if your using a spacer. Although, I never got around to putting longer studs in the front and I havn't had any issues in the couple of years that I've had my skinnies. There is always the possibility of breaking one though, I've seen it happen on a newer Mustang with Prostars.


BTW: I forgot to ask, the wheels are deffinatly hitting the caliper and not the inner wheel well right? When I ground my rears acouple of weeks ago I had to load the suspension because the tire was hitting the bump stop and part of the wheel well.

Would u get a 15x10 7.5bs or go with a 15x8 5.5bs? Thanks for the info, I had the wheels in the air when test fitting them, so I may ground down enough. I want to get the right BS and fit so i don't have to grind more down.

Both the 15x10s (7.5bs) and 15x8s (5.5bs) should fit about the same and sit in the same location. You might have to grind just a touch more for the 15x10. I went 15x10 so I had more of a choice with tire selection and they look good too. You can run a small spacer if you want in the rear but deffinatly get some hardend longer studs.

Are you using paint or a machinest dye to see exactly where it's hitting? When I did mine it seemed like it was hitting everywhere but after painting the caliper and puting the wheel on it was only acouple of problem areas.

Never tried it but will thank you for the help. I'm going for 15x8 for the rear.
