Wilwood Front Black 12.19-Inch Drilled/Slotted Kit, Ford Mustang II/Pinto/Mercury Bobcat (1974–1980)

This Wilwood front package pairs black forged Dynalite calipers with drilled/slotted 12.19-inch rotors and replacement hubs. The 0.81-inch-wide vented friction rings suit the specified original disc spindle, using the supplied five-lug hub arrangement. It is not the front drum-spindle kit. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Check the Mustang II, Pinto or Bobcat model/year row and confirm the spindle originally used disc brakes. Match the wheel's bolt pattern and register to the replacement hub. Hydraulic lines are separate installation items. Use the profile drawing to inspect clearance behind the spokes as well as around the rim barrel, even though the nominal wheel mounting offset remains at the stated OE position.

Match the individual model, year, submodel and brake configuration in the fitment table below.
