The left-side rear slotted rotor 380.30.0047.451 from Performance Friction is the genuine OEM replacement used exclusively on the Porsche 991 Cup and Cayman GT4 Clubsport. Engineered to the same exact specifications that PFC supplies to Porsche’s factory motorsport teams, this rotor delivers optimal thermal management and braking consistency under the harshest track conditions.

Measuring 380mm in diameter, this slotted ring supports efficient gas and debris evacuation, helping maintain clean pad contact and consistent bite throughout long race stints. Its robust construction ensures minimal distortion and fade—even during heavy braking sessions on demanding circuits.

This rotor is sold ring-only; the aluminum hat from the original assembly is reused, keeping production costs and waste down. The package includes a full set of mounting hardware to guarantee a precise, bolt-on fit. Note that this rotor is only compatible with the Cup and Clubsport models—it does not fit street 911 GT3 or Cayman GT4 cars.

Perfect for updating worn brake components or preparing your factory-spec vehicle for a race weekend, the 380.30.0047.461 provides the reliable OEM-level stopping power that serious racers demand.
