Product details
Seventy-two straight vanes are packed into this compact 11.00-inch Spec-37 ring. GT slots and balancing are combined with a six-bolt attachment, so it fits a different hat interface from the larger eight- and twelve-bolt GT families. Wilwood Engineering, established by Bill Wood in 1977 and based in Camarillo, California, designs and manufactures disc brake systems. Its component range spans brake rotors and calipers alongside master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. The complete brake system governs which components belong together.

Fitment & Compatibility
Compare the existing hat interface with the 6 x 6.25-inch rotor pattern, then check the 5.59-inch centering register. Proper axial placement and full pad contact are required around the 11.00-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.
