Default To fit Prostars How much grinding?

How much is it safe to grind cuz on the fronts the wheels dont fit and I grinded alot already and still rubs on it. Is ther a caliper that I can get with no grinding? maybe the LT1's?

From what I have seen you can fit them on LT1 calipers, But on ls1 calipers there is LOTS of grinding to do!!! Just be sure to keep test fitting your wheels so you dont go to far!

if you run 5/16" wheel spacers up front, you won't need to grind any at all up there. Just the rears need to be ground then, even with 5/16" spacers back there.

I ground (front & rear) mine til they fit, with no spacers. They have been that way for two years now, and havent had any problems. But, it is ALOT of grinding that has to be done...

Enough to get them to fit it is. Backs you about half to take those little indents out. Not to bad though. I've done 2 cars so far.

If you run them grind them. Spacers are are like a hot girl with a STD. You know you want it but you know you shouldn't and it WILL catch up with you if you do.

Nice decision on doing. You will be happy you did no bullshit spacers to worry about.

I'd like to see what your front calipers look like. I had to grind the sh*t out of mine to fit the 3.5s up there.
