I have a 91 Firebird with the WS6 package, disk brakes all the way around. I like the regular prostars better than the XP ones because they are lighter and cheaper. I heard i Might have to grind down my brakes to get them on though.

Is this correct? I guess I can use the XP's if I have to.

They should fit fine. Even if you do have slight running you can grind then down a bit. I had to slightly grind to clear my LS1 brakes, but you should be fine with yours.

 

What lug nuts did you use? They sent me SST Mag 12mm x 1.5 open ended nuts. I like the closed end better for looks I guess. Can I use those?

Havent even tried these yet, Im still at work

Mcgard lug nuts?? Where do you get them, what size do I need?

 

I got mine from Jeg's. I honestly can't remember the size now, but if you call up jeg's they'll be able to help you out.

 

I see them on the mcgard website. I guess I will make sure of the size first. The ones they sent are 12mm x 1.5, I think this is right, but they are open ended for extra long racing studs. The closed ones look better, I just need to make sure I can use them. They Mcgard website has some 12 x 1.5 extra long shank for Weld and Crager wheels, and they are closed end, I think these are the ones
