Product details
Left-hand cooling vanes establish the installation side of this 13.06-inch GT casting. Its slotted faces and thick Spec-37 friction section are carried by an eight-hole mounting flange, giving it different hardware requirements from the narrower twelve-bolt versions. Founded by Bill Wood in 1977, Wilwood designs and manufactures disc brake systems in Camarillo, California. Its range includes calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. Rotor choice belongs within that complete system: the caliper, pad, mounting hardware and intended duty must work together.
