Wilwood Drilled Front Brake Conversion, Ford Focus ST (2013–2018), Black Six-Piston Calipers, 12.88-Inch Rotors

This Wilwood Focus ST front package pairs black six-piston calipers with drilled/slotted 12.88-inch rotor rings on separate hats. The selected brake assembly includes BP-10 pads, radial mounting components and the specified front flex lines. It is intended for the compatible original ST hub and upright arrangement; a Focus model name or a previously enlarged rotor does not alone establish the correct installation. 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

Read the 2013–2018 ST application and inspect any replacement spindle or hub against the installation geometry. Seat the hats correctly and follow the bracket procedure for rotor/caliper alignment. Compare the actual wheel interior with the full template, since nominal diameter does not establish spoke clearance. Secure the supplied hoses clear of the tire and moving suspension. After confirming free rotor movement, assess pedal travel and front/rear hydraulic balance with the vehicle's installed rear brakes.

Match the individual year, model, submodel and equipment conditions in the fitment table below.
