Product details
A scalloped perimeter removes material from this HD rotor while retaining a Spec-37 heavy-wall casting. The 11.75-inch ring has 36 right-hand curved vanes and a plain contact surface, distinguishing it from both slotted GT and straight-vane Ultralite designs. 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.
