Product details
This black electro-coated version retains the 12.88 x 1.25-inch geometry of the right-hand GT rotor. The protective treatment accompanies a slotted Spec-37 ring with 48 curved vanes, rather than changing its mounting dimensions or supplied burnish condition. Camarillo, California is home to Wilwood, founded by Bill Wood in 1977. The company designs and manufactures disc brake systems for motorsport, street performance and specialized applications, supplying rotors, calipers, master cylinders, valves, fittings and lines. Matching the rotor to the complete assembly matters as much as selecting its diameter or surface treatment.
