Product details

The black SRP version combines patterned front rotors with new five-lug hubs on the specified GM spindles. The supplied black powder-coated 4-piston calipers and 12.19-inch SRP drilled-and-slotted rotors are configured for listed 1970–1978 GM 11-inch-rotor spindles. 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

Identify the original 11-inch-rotor front spindle before selecting this GM hub conversion. The listed vehicles span 1970–1978, but the supported years and spindle qualifiers differ between models. DS480 requires modifications to the original spindle, so this installation needs more than removal of the old caliper and rotor. The new hubs carry their own 1/2-20 wheel studs and offer the specified wheel bolt circles; verify the intended wheel pattern before assembly. A front disc-kit application should not be confused with parking-brake equipment mentioned in a general vehicle note. This front package supplies no rear parking-brake conversion. Check wheel placement, bearing installation and hydraulic hose travel as part of the completed assembly.

Use the complete vehicle row and its application notes below to check model year, trim and original brake equipment.

  • Wheel-size guide: 15 in; 381 mm minimum nominal diameter; verify actual template clearance.

Package and installation requirements

  • Follow DS480 for spindle preparation and wheel clearance. Confirm brake-hose routing and master-cylinder compatibility as part of the complete system.
  • Included hubs provide 5 x 4.5 and 5 x 4.75-inch bolt circles with 1/2-20 wheel studs.
  • 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.
  • Wilwood specifies a -0.28-inch hub offset per side. Confirm the resulting wheel position on the installed spindle along with the caliper-clearance template.
