Wilwood Rear 11.00-inch GTB Slotted Rotor with Black Finish and 2.32-inch Offset

GT slots provide the friction-face treatment on this deeper-offset rear rotor, and black electrocoat protects the iron casting. The 2.32-inch hat position and 7.24-inch internal drum must agree with the rear kit's bracket and parking-brake shoe arrangement. This component comes from Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. Wilwood designs and manufactures disc brake systems, including calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications, with compatibility determined by the complete brake assembly.
