Wilwood Front GT Rotor Conversion for Marauder, Crown Victoria, Grand Marquis & Town Car, Red Superlite Calipers & 14-Inch Rotors

This Wilwood Superlite 6R kit is a front 14-inch Superlite disc upgrade for Ford Panther Platform: Crown Victoria, Town Car, Grand Marquis and Marauder. The 14-inch rotor package keeps a narrow six-piston caliper design and requires an 18-inch nominal wheel before profile checks. Wilwood Engineering began in 1977 with founder Bill Wood and is based in Camarillo, California. It designs disc brake systems and components for racing, performance-road and specialized use, from calipers and rotors to master cylinders, valves, fittings and brake lines; the complete system determines component selection.

Fitment & Compatibility

The exact listed applications cover 2003–2011 Crown Victoria, Town Car and Grand Marquis and 2003–2004 Marauder. Match wheelbase and factory spindle. DS-1241 limits the named 220-14690 hose reference to Crown Victoria; other cars need individually confirmed hoses. Reposition Crown Victoria hardlines carefully as instructed. Models covered: Crown Victoria, Town Car, Grand Marquis and Marauder. Use the complete application table at the bottom for the precise year, submodel, brake option and note attached to each row.

PMB Performance brings 20+ years of parts and fitment experience to brake-system selection. Share the actual spindle or axle details, existing brake package and wheel measurements if you need help confirming this configuration.
