They will only fit if you also get the GT front bracket. The rotors are bigger and the stock V6 bracket doesn't put the caliper out far enough.
But that is the only other thing you need. The calipers and pads are the same. So if you want those bigger rotors, just buy some of the GT caliper brackets and swap them.
