Product details
The 10.25-inch bolt circle is the crucial mounting distinction on this left-hand 16-inch GT ring. Its 1.38-inch Spec-37 casting uses 60 curved vanes and black electro-coat, with a 9.64-inch register suited to the matching separate hat. 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.
