Product details
A one-inch working width distinguishes this right GT rotor from the thicker dynamic-mount rings. Its 13.00-inch diameter and 48 curved vanes are combined with twelve mounting lugs for the appropriate 8.80-inch carrier. Wilwood Engineering is based in Camarillo, California and was founded by Bill Wood in 1977. It designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. The range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines, all of which require selection around the full brake system rather than an isolated dimension.
