Product details
Factory burnishing distinguishes this right-hand GT rotor from the unburnished version of the same dimensions. Its 1.25-inch-wide Spec-37 ring retains GT slots, 48 curved vanes and the eight-bolt hat interface. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California, where it designs and manufactures disc brake systems and components. Calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications; each part must suit the complete brake system.

Fitment & Compatibility
Use the complete brake kit to establish axle location, caliper spacing and wheel clearance. This 12.19-inch rotor needs a 8 x 7.00-inch mounting interface with 6.38-inch centering. Pad compound and sweep must be suitable for the ring material and 1.25-inch working section. Select pads and operating duty to suit the rotor material and the intended brake system.
