Rear Disc Brakes
Looking to replace the rear brake rotors on my stock 9-bolt here soon. I know parts are difficult to find since it's been rebuilt within the last year. I'd like to upgrade to different brakes, but don't have the cash for a major upgrade. I'm looking at a set of drilled/slotted rotors but I'm not sure if they're for the 10-bolt or if they'll fit the 9-bolt. The only thing Summit gives about fitment is they fit the 1988 Trans AM. Are the rotors different between the two rears or are do they have the same rotors? I know backing plates are different based on things I've read here on TGO. Appreciate the info.

Re: Rear Disc Brakes
All brake parts are common between the 9 and 10 bolts, except the backing plates.
