Product details
Black electro-coat identifies this right-hand GT rotor’s finish without changing the narrow 0.81-inch section. The 12.88-inch iron ring uses 48 curved vanes and GT face slots, with an 8.25-inch register for the separate hat. A rotor must suit both the mechanical installation and the rest of the braking system. Wilwood brings that system perspective to its calipers, rotors, master cylinders, valves, fittings and lines, designing and manufacturing disc brake systems for motorsport, street performance and specialized applications. Bill Wood founded the Camarillo, California company in 1977.
