Wilwood Left GTB Black Rotor with 14.25-inch Slotted Face and 1.25-inch Width

A black-finished left GTB rotor completes the matching heavy-wall configuration without adding a hat to the purchase. The 1.25-inch-wide ring is dynamically balanced and must retain the intended left-hand installation orientation. Founded by Bill Wood in 1977, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its calipers and brake rotors work alongside its master cylinders, valves, fittings and brake lines, with each individual component selected according to the complete system's requirements.

Fitment & Compatibility

For an assembly designed around a 14.25 x 1.25-inch friction ring. Use the correct rotor fasteners and hat, checking both the 12 x 8.75-inch attachment circle and the 8.25-inch registration. Determine axle suitability from the complete brake kit, not from the rotor's diameter. Select pads and operating duty to suit the rotor material and the intended brake system.
