Wilwood Right Black GTB Lug-Mount Rotor, 15.00 x 1.25-inch, 8.80-inch Interface

A larger 8.80-inch lug interface supports this right-hand fifteen-inch GTB ring. Its 72-vane Spec-37 casting uses the 1.25-inch friction section with the dedicated dynamic-mount hat and retaining arrangement. Wilwood Engineering designs and manufactures disc brake systems from its base in Camarillo, California. Bill Wood founded the company in 1977; its range now includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized uses. Selection must account for the entire brake system.

Fitment & Compatibility

Requires the specified dynamic-lug hat or carrier and its retaining hardware. The lugs accommodate the intended mounting movement; conventional bolt-hole hats are not interchangeable. Check the rotor's diameter, working width and registration against the complete caliper assembly. Select pads and operating duty to suit the rotor material and the intended brake system.
