Fitment & Compatibility

Match the Mazda's exact year and front spindle configuration to the table and DS818. The large rotor needs an 18-inch conditional wheel envelope, and the full caliper section must fit behind the spokes. Mount each ring in the direction prescribed by Wilwood, keep the calipers in the correct handed locations and set the shims before final tightening. Choose flex hoses separately. Hub inspection, proper hat seating and the required post-installation brake tests are part of completing the conversion.

Check the individual year, model, submodel and equipment conditions in the fitment table below before ordering.
