I have to put some new rotors on my GP. Rears at a minimum, probably will do all four. So I've considered taking the rotors off my Impala and buying new ones for it, then putting the Imp rotors on my GP. Factory stuff still on them all around. What can I swap/move without having to upgrade brake caliper hardware? I think the Imp has 12" fronts, 10" rears, and the GP has 10" on both.
ZZP has fronts and rears for $50 each, so I've also thought of just buying 4 new ones for the GP and worry about the Imp rotors later as it would probably make more sense to do all four at once.
Thoughts/suggestions/deals on rotors?
