Product details
The ULGT rotor applies asymmetrical GT slots to the sixteen-vane lightweight casting. This right-hand 11.75 x 0.99-inch ring is intended for specified moderate-temperature dirt and asphalt racing duty with a matching eight-bolt hat. 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.
