13.5 inch I'm pretty sure for the front rotors( same size as stock 03 cobra front rotor). Huge four piston Alcon calipers with mounting hardware and slotted rotors. Also have brackets to mount 13 inch rOtors On solid axle. Also have newer mustang 03 cobra rear calipers. Looking for 1200 for whole set up. Maybe have rear 13inch rOtors as well. Email for pictures and more info. These brakes are comparable to brembo
