Product details
Plain vented rotors pair with red FDLI calipers in this new-style big-Ford rear package. Its forward caliper locations, supplied parking assemblies and axle-end geometry distinguish it from other kits sharing the same rotor diameter. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its component range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines. The complete braking arrangement determines which individual components are appropriate.

Fitment & Compatibility
This rear-axle version places both service calipers ahead of the axle. It requires the new-style big-bearing Ford housing end and a 2.50-inch offset specified in DS-557; it is not the staggered-mount version. Confirm the actual installed axle dimensions for the Lincoln Town Car application in the table below, including bearing and flange clearance. The integrated drum parking system needs separately selected cables and clevises; universal kit 330-9371 is available. Hydraulic lines and fittings are also separate. Nominal minimum wheel diameter: 15 in; 381 mm. Compare the actual wheel barrel and spokes with the linked clearance drawing; diameter alone does not establish fit.
