PFC V1 Rotor/Hat Assembly - Left - Porsche 997.2 GT3/GT2

The PFC V1 Rotor/Hat Assembly (Left, Part #379.067.85) is engineered to push braking performance to race levels while maintaining durability under extreme conditions. This two‑piece design uses a floating hat system that allows the rotor ring to expand and contract both radially and axially—dramatically reducing warping, vibration, and pulsation compared to fixed or one‑piece rotors.

Crafted from high carbon iron infused with copper and molybdenum, the rotor disc material delivers exceptional strength at high temperatures. Vanes are precision‑turned on both the inside and outside to aid airflow, manage heat soak, and stabilize the rotor under high‑load braking. Tight manufacturing tolerances—runout under 0.001", thickness variation under 0.0003"—ensure smooth, confident pedal feel.

What makes the V1 assembly especially practical is its compatibility with the factory Porsche GT3/GT2 calipers, and a reusable hat design—when the disc wears, only the rotor ring needs replacement. This assembly is built for drivers who do frequent track work: the aggressive braking, repeated heat cycles, and the constant demand for consistency from lap to lap.

• Genuine PFC part # 379.067.85 – Left side rotor/hat for Porsche 997.2 GT3/GT2
• Two‑piece floating rotor/hub design to allow both radial and axial motion of the rotor ring
• High carbon, copper/molybdenum alloy disc for high temperature strength and resistance to heat distortion
• Precisely machined vanes (ID & OD) for enhanced cooling and airflow management
• Tight manufacturing tolerances (runout < 0.001", thickness variation < 0.0003") to reduce vibration & brake pedal pulsation
• Reusable hat assembly – cost savings over time; only rotor ring needs replacement when worn
• Direct drop‑in fit with factory calipers — no modification required
• Ideal for track, time attack, endurance or high‑duty street applications where brake temperatures are high
