Designed exclusively for Porsche 997 GT3 Cup models (Gen 1 & 2), the PFC Rear V3 Slotted Rotor/Hat Assembly (P/N 348.075.61) takes braking performance to a new level. This 348 mm diameter, 29 mm-thick two‑piece rotor is built from high‑precision cast steel, with all external surfaces machined to ±0.004″ for exceptional dynamic, thermal, and mechanical balance—meaning warping and vibration are virtually eliminated .
At the heart of its design is PFC’s patented V3 dual‑turn snap‑ring system, which secures the rotor to the hat in seconds—no bolts, no torque wrenches, no hassle. This innovative design reduces unsprung weight and streamlines pad changes under race conditions. The slotted pattern improves heat dissipation and resistance to brake fade, while the full-floating configuration allows natural expansion for smoother braking and longer life .
Built in the USA and race‑proven across Porsche Cup series, this rotor assembly delivers durable, fade-resistant, and repeatable braking—lap after lap.
