Wilwood Rear Plain-Rotor Kit with Red D154 Calipers Ahead of Axle, Big Ford New Style 2.50-Inch Axle Offset; Conditional Lincoln Town Car 1990

This red Wilwood rear package is the forward-caliper version for a Big Ford New Style housing at 2.50-inch offset. Plain vented rotors work with hydraulic D154 calipers, while internal shoes provide parking operation. The listed Town Car year requires confirmation of the axle end and bearing geometry before fitment can be established. 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. Its product range serves motorsport, street-performance, and specialized applications, with individual components selected to match the requirements of the complete brake system.

Fitment & Compatibility

DS862 identifies the brackets that place both service calipers ahead of the rear axle. Verify that orientation clears the shocks and matches the installation space, then measure flange dimensions and offset. Confirm the 1990 Lincoln application with Wilwood. The rotor hats must fit the axle flange and wheel studs. Add parking cables and hydraulic hoses separately and check the conditional 16-inch wheel profile, assessing any 15-inch option individually rather than by diameter alone.

Check the individual year, model, submodel and equipment conditions in the fitment table below before ordering.
