Wilwood Black-Caliper Front Disc Conversion with Drilled 12.88-Inch Rotors and Lines for Listed Five-Lug Mini Cooper Applications

Black six-piston calipers operate SRP rotor rings on aluminum hats in this Mini front assembly. The supplied BP-10 pads and hydraulic hoses complete the documented brake-side package while retaining the matched original wheel hubs. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc braking systems and components for street-performance, motorsport and specialized use. Its calipers, rotors, master cylinders, valves, fittings and brake lines are chosen around the hydraulic, mounting and balance needs of a complete system.

Fitment & Compatibility

Use only the five-lug Mini applications below, including the specific hardtop/body and trim conditions. DS1128 requires the hub pattern and register to match the hats. Check complete spoke/barrel clearance and line travel; the nominal wheel minimum is 17 inches.

Models represented in the detailed applications: Cooper. Each is subject to its individual year, trim and brake/suspension condition. 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.
