Wilwood GT-Rotor Front Conversion with Red Superlite 6R Calipers and Flexlines for Listed 2014–2017 Five-Lug Mini Coopers

Red Superlite calipers use BP-10 pads against slotted GT rotor rings in this front Mini configuration. The two-piece hat/rotor assemblies fit the verified factory five-lug hubs, with a model-specific front flexline set supplied. The manufacturer, Wilwood Engineering, was founded by Bill Wood in 1977 and is based in Camarillo, California. It designs and manufactures disc systems and component parts across motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and lines. Those individual parts must be selected in the context of the complete brake system.

Fitment & Compatibility

Identify the exact Mini body/trim and year below before checking DS1128. The stated 5 x 112 mm five-lug pattern is a required interface, not a conversion for earlier four-lug cars. Confirm the hub register and nominal 17-inch wheel envelope, then verify hydraulic hose routing.

Listed model families are Cooper; the individual year and brake/spindle conditions remain decisive. Use the fitment table below to confirm year, model, trim and brake or suspension options.

With more than 20 years of parts experience, PMB Performance can help review the specified brake arrangement. Include the vehicle year and details of any hub, spindle or suspension changes.

Check the Installation instructions for the full assembly and wheel-clearance requirements.
