Product details
Polished calipers give this five-lug Pinto/Mustang II assembly a bright finish beside its SRP discs. For 1971–1980 Ford Pinto / 1974–1978 Mustang II, Wilwood specifies polished 4-piston calipers and 12.19-inch SRP drilled-and-slotted rotors in this front package. Bill Wood founded Wilwood Engineering in 1977. From 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. This kit should be matched to the hydraulic and mechanical requirements of the complete vehicle.
Package and installation requirements
- Wilwood marks this kit obsolete without identifying a replacement number on the current page. Confirm availability and the correct replacement with PMB Performance or Wilwood before ordering.
- The 0.74-inch track-width change is per side; confirm fender, suspension and wheel clearance.
- Wheel contact surfaces must be fully supported by the hub face. Where they overhang it, Wilwood requires its separately sold 6.60-inch-diameter x 0.20-inch steel spacer. For stamped-steel wheels that do not overhang, the instructions recommend the separate 6.15-inch-diameter x 0.09-inch hub shield. Verify the exact wheel with the installation instructions.
Fitment & Compatibility
The instructions identify 1971–1980 Ford Pinto and 1974–1978 Ford Mustang II front spindles. This kit includes five-lug hubs; it does not retain a factory four-lug wheel pattern. Wilwood states a 0.74-inch outward wheel-location change per side. Check wheel placement and clearance before choosing wheels.
Before ordering, compare the wheel profile with the Wilwood clearance diagram. The stated minimum size does not establish spoke or barrel clearance for every wheel of that diameter.
