Product details
A 1.38-inch friction section and compact twelve-hole flange distinguish this 12.72-inch GT rotor. The right-hand Spec-37 casting uses 48 curved vanes and slotted contact faces, with the mounting ring concentrated around a 6.25-inch center register. 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.
