Here is the new rear disc setup for my Duster. Baer 13 inch rotors with 17 inch Weld wheels and drag radials. These rear brakes are mostly for looks. They'll work nice but I don't really need 13 inch rotors on the rear. A drum brake would probably work fine for this car since max speed is about 125 mph. A 10 inch disc brake would also work but would look wimpy so I went with the big 13 inch rotor.
