Wilwood Right GT Heavy-Wall Rotor, 14.25 x 1.25-inch with 72 Curved Vanes

A 1.25-inch heavy-wall Spec-37 casting underpins this right-hand GT ring. Its slotted face and 72 curved vanes make it a suitable candidate for high-temperature systems after the 14.25-inch diameter, mounting geometry and pad sweep are matched. Bill Wood established Wilwood Engineering in 1977; the company is based in Camarillo, California and designs and manufactures disc brake systems. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form its range for motorsport, street-performance and specialized applications. Compatibility depends on selecting those parts for the requirements of the complete brake system.

Fitment & Compatibility

Use the complete brake kit to establish axle location, caliper spacing and wheel clearance. This 14.25-inch rotor needs a 12 x 8.75-inch mounting interface with 8.25-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.
