Wilwood Red Superlite Front Disc Package, 12.88-Inch SRP Rotors, Dodge/Plymouth Roadrunner/GTX/Charger/Coronet Super Bee/Satellite/Coronet/Belvedere/Fury/Savoy/330/440/Polara/Cuda/Barracuda/Challenger (1962–1972)

Red six-piston calipers and drilled/slotted 12.88-inch rotors form this Wilwood front disc conversion for the specified Mopar drum-spindle chassis. Replacement aluminum hubs, bearing components and radial brackets provide the mounting hardware for the selected spindle. These are conversion components rather than a service replacement for an arbitrary factory disc brake assembly. 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

Use the drum-brake spindle application as the starting point, then verify the mounting pattern and wheel-to-caliper envelope. Wheel track increases 0.13 inches on each side with this hub arrangement. The two-bolt master-cylinder mounting option may need the appropriate four-bolt adapter on applicable Mopar installations. Choose brake hoses by routing and travel, and use the installation diagram to establish spoke clearance before assembly.
