The corvette calipers have stiffening heatsinks on the top of them that extend all the way to the front. They are cast different and I believe have slightly smaller pistons as opposed to the LS1 calipers. The LS1 rotors are the same thickness as the vette ones, which makes the calipers innerchangeable. The can be swapped back and forth, but you will have to have 2 different mounting brackets because the vette rotors are larger in circumfirence. The abbunctments for the vette and ls1 calipers are different, but you can use the ls1 one`s on the vette calipers.
