The Performance Friction 380.34.0062.451 is a left-front slotted rotor ring designed as a direct replacement for the V3 Direct Drive assembly (P/N 380.070.63), used on Porsche 991 GT3 and Cayman GT4 models equipped with PFC’s advanced race braking system.

Engineered for high-performance applications, this 378mm × 32mm rotor features PFC’s V3 retention system—a two-turn snap-ring mechanism that allows for ultra-quick ring changes without traditional bolts. This innovation reduces unsprung weight and simplifies serviceability at the track.

Crafted from a high-carbon alloy with molybdenum and copper content, the rotor ensures excellent thermal resistance and minimal distortion under repeated high-load braking. Its precision-balanced vanes and ultra-tight tolerances help eliminate vibration and promote even pad wear, ensuring stable pedal feel throughout a race stint.

The slotted design enhances pad bite and helps evacuate gases, keeping brake temps under control and maintaining consistent performance. This rotor is sold as a ring only—designed to work with your existing aluminum hat from the 380.070.63 V3 assembly—and comes complete with all required mounting hardware.
