Quick question
Will 15" rims clear the 89 rear discs? I am going to the track in 2 weeks and could borrow a set of 15" hoosiers, so I would like to try them out and was wondering if they'll clear the PBR brakes?

If you're mounting them on factory 15" wheels I don't know if they'll clear.
I run (at the track only) 15"x9" Weld Draglites w/ 5.5 " backspacing. I had to grind the fins off the PBR calipers for clearance. I still use 3/16" thick Moroso spacers for added clearance. Keep in mind that using the spacers will reduce the stud length, but mine are fine...barely. I'd upgrade to longer studs. Also the spacers are safe as long as you don't go over 1/4" thickness.
