Product details
The black-finished GTB alternative keeps the same non-directional 36-vane layout and 0.81-inch width. Its large 14.00-inch slotted ring needs the correct hat register and caliper pad sweep, even when an existing mount shares the bolt circle. 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
Installation requires a hat or hub designed for the 8.25-inch rotor register and 12 x 8.75-inch attachment. Verify wheel clearance around the complete caliper, along with the rotor's 0.81-inch width. The ring alone does not define a direct-fit vehicle or axle application. Select pads and operating duty to suit the rotor material and the intended brake system.
