Product details
The front twelve-bolt dynamic rotor kit pairs stainless twelve-point fasteners with T-nuts, flat washers and the T-nut tool identified in the service listing. Its 1/4-28 thread and 0.750-inch length distinguish it from the one-inch coarse-thread socket-bolt arrangement. Founded by Bill Wood in 1977, Wilwood Engineering designs and manufactures disc brake systems in Camarillo, California. Its calipers, rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications, with each component selected to suit the complete brake system.
