i tried to check things up and seems like 05-present, the rear calipers are all the same. even on the GT500, not sure about the V6 models if they are all interchangeable from 05-present. please correct me if I'm wrong.

when i thought i cracked the rear caliper from the rotor hitting the caliper during a curb side hit.. it was actually the caliper bracket that caliper slides on that is cracked, maybe if i can find a used bracket from 05 to present and keep my 2013 caliper it would all work out just great so i don't have to bleed the brakes etc.. plus ill be painting the calipers so it would be no bigy at all.

however if someone has a LH rear caliper bracket for cheap please let me know, ill buy it with the rear caliper if the price is good.

Im waiting for the 14" BAER rear rotors, it will be an interesting upgrade for the rear, since the rear look so tiny compared to the front Brembos lol ...
