sorry if i put this in the wrong section first off. Ok the other day i was having a discussion with another mk3 supra guy bout upgrading the rear to mk4 rotors and calipers. now obviously it can be done and guys make kits i think too. any way he was saying that he was having a hard time finding calipers and rotors, well i was lookin it up on autozones site and saw that they sell remaned ones. my qustion is has anyone ever bought any, because im wondering if you could just buy the calpiers like that then just by some aftermarket rotors, or if there are parts missing? sorry if this is confusing at all lol
