These are the rear rotor hats that come with the Brembo GT rear kit (345x28mm) for the C5 corvette. I bought the kit for a custom project and didn't need these original hats. New, just dusty from sitting on a shelf for years. They are crazy expensive new from Brembo, if they would sell you one. You can recreate the whole kit with just rotor rings, calipers, and pads, for much less then the new cost of the complete kit. Priced for quick sale.
