These have been on my car for 3k, and have very little wear. They will fit GT500 as well as 11+ mustang w/Brembo brakes. These are lighter than stock and save just under 6lbs of rotational weight each. They also greater improve stopping power. Going with a lighter drag race rotor. Asking $425 for the set.
