Fitment & Compatibility

Confirm space for the 14-inch rotor and caliper combination using DS818 before ordering wheels or dismantling the car. The conditional minimum is 18 inches, subject to spoke shape and barrel geometry. Inspect the retained RX-7 hubs for register damage or runout and match the listed 1993–1995 application. The kit does not include hydraulic flex lines; select them for the actual car and provide strain-free routing. Follow the left/right caliper and rotor instructions rather than treating the two corners as interchangeable.

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