Product details
Wilwood's Land Rover front hat uses a 12 x 10.75-inch rotor circle. Verify the 3.12-inch register, 0.810-inch offset and correct truck assembly. Bill Wood’s 1977 founding of Wilwood Engineering began a disc brake design and manufacturing business based in Camarillo, California. The range includes master cylinders, calipers, rotors, brake lines, valves and fittings for motorsport, street-performance and specialized vehicles. Component selection must consider the complete braking arrangement.
