Product details
A 16.00-inch outside diameter and 1.50-inch width make this one of the larger GTB rings in the group. Its right-hand 60-vane casting needs a brake system with the correct radial clearance, hat geometry and pad coverage. 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.

Fitment & Compatibility
For an assembly designed around a 16.00 x 1.50-inch friction ring. Use the correct rotor fasteners and hat, checking both the 12 x 9.75-inch attachment circle and the 9.03-inch registration. Determine axle suitability from the complete brake kit, not from the rotor's diameter. Select pads and operating duty to suit the rotor material and the intended brake system.
