The DFC Geomet-coated drilled rotor for 2018–2021 Subaru WRX STI (rear) is a hi‑carbon alloy replacement designed to restore braking balance and control temperatures under load. The drilled design supports cooling and pad bite while a precision-turned surface improves break-in behavior. Geomet coating provides corrosion resistance and the rotor is finished and balanced to reduce vibration and maintain consistent stopping performance.
