Product details
Five-lug hubs make this Pinto and Mustang II kit a brake and wheel-mounting conversion. This Forged Dynalite front hub brake kit combines black powder-coated 4-piston calipers and 12.19-inch plain-face rotors. Founded in 1977 by Bill Wood and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to work together as a complete brake 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.
Use the wheel-clearance drawing in the installation instructions before purchase. The catalog minimum diameter is a guide; barrel shape, spoke clearance and wheel offset still determine fit.
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.
