Product Description

The EBC RK645 Rear Brake Rotors are OE-quality replacement rotors designed specifically for the Mazda RX-7 FD3S platform. Built from high-grade G3000 gray cast iron, these rotors restore factory braking performance while offering improved durability and corrosion resistance for long-term use.

Each rotor features a vented internal design that helps dissipate heat during aggressive driving, reducing the risk of brake fade. The Thermic Black coating protects non-friction surfaces from corrosion while maintaining a clean appearance and extending service life.
