Product details
A black electro-coat finish distinguishes this left-hand 12.88-inch GT rotor from the uncoated version. Under the finish is the same slotted Spec-37 architecture, with 48 curved vanes and a 1.25-inch nominal thickness. System compatibility is central to choosing a replacement rotor, including its relationship to the caliper, pad and mounting hardware. Wilwood designs and manufactures disc brake systems in Camarillo, California, offering calipers, rotors, master cylinders, valves, fittings and lines across motorsport, street performance and specialized applications. The company was founded in 1977 by Bill Wood.
