Wilwood Front GT Rotor Kit with Red Superlite 6R Calipers, Mazda RX-7 1993–1995, 12.88-Inch Rotors

GT slotted rotors, red radial-mount calipers and BP-10 pads are the selected combination in this Wilwood Mazda RX-7 front kit. Each six-piston caliper works over a 12.88-inch vented iron ring. Separate hats retain the factory-hub mounting layout, while the supplied brackets establish the new caliper position. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines. Its product range serves motorsport, street-performance, and specialized applications, with individual components selected to match the requirements of the complete brake system.

Fitment & Compatibility

The verified application table identifies the individual 1993–1995 RX-7 years. Check the car's actual hubs and spindles and use the DS817 assembly drawing to establish alignment. A proposed 17-inch wheel needs a full profile comparison; width or diameter alone cannot guarantee clearance behind the spokes. Hydraulic lines are a separate choice and must be compatible with the caliper connection and suspension movement. Confirm wheel-stud engagement and hat seating before bedding the supplied pads.

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