Fitment & Compatibility

Confirm the actual NC year, trim and unmodified hub interface against the applications below. The installation calls for dust-shield trimming before the rotor assemblies are fitted. Use DS1106 to place the driver/passenger cables and check hose travel, parking operation and wheel clearance.

Listed model families are MX-5 Miata; 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.
