PFC Rear Slotted Rotor - Left - Porsche 992 GT3 Cup
The PFC OE Slotted Front Rotors are a direct replacement for the original rear rotor hats of the Porsche 992 GT3 Cup. Precision-engineered for uncompromising track performance, and measuring 380 × 32 mm, this rotor is a direct replacement for OEM components and mounts to the factory front hat. The slotted design improves cooling and pad contact under high thermal loads, enhancing braking control during race conditions. Trusted by top-level GT teams, PFC delivers durability and repeatable performance lap after lap.

Designed exclusively for Porsche 992 GT3 Cup, the PFC Slotted Replacement Rotor (P/N 380.32.0052.452) takes braking performance to a new level. This 380 mm diameter, 34 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
