Product details
This left-hand GT ring places a 12.60-inch slotted friction surface around a compact twelve-bolt mounting center. The 1.25-inch Spec-37 section and 48 curved vanes suit the corresponding complete brake assembly, with a listed 15.60-lb weight. 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.
