Product details
The left-hand large-diameter GTB rotor carries a 1.50-inch-wide Spec-37 friction ring. Its 60 curved vanes and slotted face are intended for the matched high-duty system, with wheel clearance checked around the entire 16.00-inch assembly. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Its motorsport, street-performance and specialized components are selected around the requirements of the whole braking system.

Fitment & Compatibility
Compare the existing hat interface with the 12 x 9.75-inch rotor pattern, then check the 9.03-inch centering register. Proper axial placement and full pad contact are required around the 16.00-inch ring. A matching wheel-bolt pattern is not a substitute for this rotor-to-hat check. Select pads and operating duty to suit the rotor material and the intended brake system.
