Product details
The Wilwood Fox Body Mustang front hat mounts a twelve-bolt rotor ring. Check the 0.810-inch offset, five-hole flange and 3.06-inch register. The manufacturer, Wilwood Engineering, was established by Bill Wood in 1977 and is based in Camarillo, California. It designs and builds disc brake systems with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications require components selected for the complete braking system.

Fitment & Compatibility
The Fox Body Mustang front conversion must specify the same hat, hub register and rotor mount. This version uses a 5 x 4.50-inch hub flange and a twelve-bolt 8.75-inch rotor circle at 0.810-inch offset. Follow the brake-kit instructions for the caliper and ring; the Mustang name does not establish fitment with original or unrelated aftermarket brakes.
