Wilwood Front Black Six-Piston Caliper/GT Rotor Conversion, Ford Focus ST (2013–2018), 12.88-Inch Rings and Flex Lines

Black Superlite 6R calipers and GT slotted 12.88-inch rotors form this Wilwood front conversion for the listed 2013–2018 Ford Focus ST. The six-piston assembly uses separate aluminum hats and BP-10 pads, with application-specific front lines included. The compatible factory disc spindle and original hub are retained, so ST equipment must be established rather than selecting from the broader Focus model range. 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 for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Confirm the ST trim and original front mounting arrangement before checking the hub register and rotor-hat seating. Follow the kit instructions to center the calipers with the appropriate bracket shims. The conditional 17-inch wheel minimum requires comparison with the actual spoke and barrel profile. Route the hoses without strain at steering lock and through suspension travel. Verify pedal travel and brake proportioning alongside the retained rear brake package before testing the completed conversion.
