Wilwood Front Black AERO6 Brake Conversion, 14-Inch Drilled Rotors for Mustang S550 (2015–2023)/Ridetech Hubs

Drilled-and-slotted 14-inch rotors and black AERO6 calipers identify this front package. The included hydraulic hoses suit the specified installation, with routing and wheel clearance checked against the actual vehicle. 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

For factory S550 installations, use only the listed 2015–2023 Mustang trim and brake-package entries; do not assume Shelby GT350/GT500 coverage. Classic Falcon, Comet, F-100 and Mustang rows require the stated Ridetech hub spindle or SLA/hub-spindle conversion, not their original spindles. DS-1076 includes front flexlines 220-13912. The wheel barrel and spoke shape must clear the 14-inch assembly.

Listed models: Falcon; Comet; Mustang; F-100. Use the fitment table below for the individual years, submodels and equipment conditions.
