Product details
The black electro-coated left-side GT ring is intended for the matching narrow 14-inch brake assembly. Its 72-vane Spec-37 core and slotted friction faces preserve a 1.10-inch thickness while the twelve-hole flange connects to a 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.
