  Common Vehicle Fitments:

The Performance Friction 380.30.0065.451 is the genuine rotor ring replacement for the V3 Direct‑Drive rear assembly (P/N 380.075.63), engineered specifically for Porsche 991 GT3 (2012–2019), Turbo/Turbo S, and Cayman GT4 equipped with PFC’s innovative V3 system.

Sized at 380 × 30 mm, this slotted, floating rotor is crafted from high-carbon alloy with copper and molybdenum, delivering exceptional thermal strength and resistance to distortion under extreme braking.

Precision-turned OD and ID vanes help maintain balance, minimizing run-out (<0.001″) and thickness variation (<0.0003″) to eliminate pedal pulsation and vibration.

PFC’s patented two-turn snap-ring retention closes the gap between the rotor ring and hat without bolts—reducing unsprung mass, speeding up service, and simplifying rotor replacement at the track.

This part is sold as the rotor ring only; it’s designed to work seamlessly with the existing aluminum hat from the V3 assembly and includes all necessary hardware.
