Wilwood GT-Rotor Rear Upgrade with Red Dynapro and MC4 Calipers, Hoses and Parking Cables, NC MX-5 Miata 2006–2015

Red calipers distinguish this GT-slotted rear package for the NC Mazda. The four-piston service brakes retain BP-10 pads, while independent MC4 mechanical calipers provide parking-brake actuation. Both the hydraulic rear line kit and replacement parking cables are part of the assembly. Wilwood Engineering, established by Bill Wood in 1977 and based today in Camarillo, California, manufactures and designs disc brake systems and their components. The product range covers brake rotors, calipers, valves, master cylinders, brake lines and fittings for motorsport, specialized and street-performance applications. Suitability depends on matching each component to the entire brake system.

Fitment & Compatibility

Use the exact 2006–2015 Miata model listing and the DS1106 rear installation. The factory dust shields need the prescribed cut, and modified hubs require a separate register/stud check. Verify full wheel clearance and correct cable-side placement before adjusting the parking mechanism.

Check the application-specific restrictions for MX-5 Miata. 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.

PMB Performance has over 20 years of experience with parts and fitment details. Contact us with the original vehicle specification and any changes to its braking or suspension system.

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