Wilwood Drilled 11-Inch Rear Conversion with Black Low-Profile Calipers for Small Ford 2.50-Inch Axle Offset

Small Ford 2.50-offset rear brakes combine black low-profile calipers, drilled 11-inch rotors and parking shoes. Check the axle register and hose route. Bill Wood’s 1977 founding of Wilwood Engineering began a disc brake design and manufacturing business based in Camarillo, California. The range includes master cylinders, calipers, rotors, brake lines, valves and fittings for motorsport, street-performance and specialized vehicles. Component selection must consider the complete braking arrangement.

Fitment & Compatibility

Use this version only with the specified Small Ford rear flange and 2.50-inch axle-flange offset, measured between the wheel-side axle-flange face and housing-flange face. Do not confuse it with the 2.66-inch Small Ford or 2.50-inch new-style Big Ford installation. Stock 1990 Lincoln Town Car compatibility is unverified. Inspect the actual axle before relying on the vehicle entry below. Low-profile Dynapro calipers work with 11.00 × 0.81-inch integral-hat iron rotors and included internal parking shoes. Hoses, cables, clevises and adapters are separate. Confirm the specified flange-diameter limit/chamfer and 3.06-inch rotor register, with the supplied 2.80-inch adapter where appropriate. Stud clearance may require rotor-hole machining. Check actual wheel clearance rather than relying on nominal 14-inch guidance.

Listed models: Town Car. See the supplied table below for each year, submodel and equipment condition.
