Will the zr1 17x11's with 315 tires fit with the prokit rear springs?

They fit, with doing the BFH mod and rolling quarter lip,

and you will hate the springs in 1 year and want different ones . . .

I disagree...I have them, no inner wheel modification. Just rolled the fender lip, because they sit right on flush with the fenders. I'm using worn stock shocks, and have had these springs on for quite awhile I'm sure it's been more than a year.

I know they are notorious for sagging in the rear, however, my car actually sits a little lower in the front. (1/4" maybe) BTW what shocks do you recomend as I'll need some later on. I'd like it run nice at the strip and around on the street. However I don't want to be broke.

You have the 36 / 38 mm offset wheels, on a Firebird, so that is why no inner wheel well mods.

Yeah i figured i would have to roll the lip and use the BFH. Thanks for the quick replies.

I did it with the 50/56 whatever offset on my Camaro. Still no inner fender BFH needed. Just rolled the lip and got an adjust. panhard bar. This pic is with prokit

how hard is it to roll the inner fender lip?

Some people use a baseball bat to do it. But eastwood sells a lip roller that bolts to your hub and you just crank it and it will roll it.

50mm 17x11 rear and 315's here with Prokit....I had to BFH and adj. Panhard AND roll my outer lips.....ALOT. But it's not hard if you're careful...
