Wilwood GT Rear Disc Assembly with Red Dynapro and MC4 Calipers, Lines and Cables for Selected 2014–2017 Five-Lug Mini Coopers

The red GT variant combines Spec-37 12.19-inch rotor rings, aluminum hats and billet four-piston service calipers. Additional red MC4 parking calipers, rear hoses and the replacement cable kit provide the documented mechanical and hydraulic connections. Wilwood Engineering is based in Camarillo, California; Bill Wood founded the company in 1977. Disc brake system design and manufacturing includes calipers, rotors, master cylinders, pressure valves, fittings and brake lines for motorsport, street-performance and specialized applications. Component selection must account for how the complete brake system mounts, operates and balances.

Fitment & Compatibility

Confirm the exact five-lug Mini configuration in the applications below. Follow DS1129 for replacing the original cables, which do not directly connect to the new calipers. Check the hub register, selected wheel clearance and unobstructed hose/cable routing before adjustment.

Check the application-specific restrictions for Cooper. A shared model name does not replace the exact year and brake/suspension configuration. Use the fitment table below to confirm year, model, trim and brake or suspension options.

For a fitment check, give PMB Performance the vehicle details and the actual brake and suspension hardware. Our team has over 20 years of experience working through parts compatibility.

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