Product details
The black SRP version combines a hub conversion with drilled-and-slotted front discs. The supplied black powder-coated 4-piston calipers and 12.19-inch SRP drilled-and-slotted rotors are configured for 1971–1980 Ford Pinto / 1974–1978 Mustang II. Wilwood Engineering began in 1977 under founder Bill Wood and is based in Camarillo, California. The company designs and manufactures disc brake systems and components for motorsport, street-performance and specialized vehicles. Calipers, rotors, master cylinders, valves, fittings and brake lines must be selected around the needs of the complete system.
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.
Check the actual wheel against the manufacturer template, including the inner barrel and back of the spokes. A nominal wheel diameter by itself does not guarantee clearance.

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.
