Product details
This rear GTB casting brings a slotted 12.19-inch service ring and the parking drum into one component. The shallower 1.91-inch hat location and three wheel-stud clearance patterns require a matching axle flange and rear conversion geometry. Camarillo, California is home to Wilwood Engineering, founded in 1977 by Bill Wood. The company designs and manufactures disc brake systems and their calipers, brake rotors, master cylinders, valves, fittings and brake lines. Across motorsport, street-performance and specialized applications, these components must be matched as parts of a complete braking system.
