Common Vehicle Fitments:

The PFC V3 Slotted Rotor/Hat Assembly – Left (Part #379.069.63) is engineered to provide Porsche 997/991 Turbo drivers with uncompromising braking performance under track and high-demand conditions. Built as a two-piece floating rotor system, it combines PFC’s precision-machined aluminum hat with a high-carbon alloy rotor ring, joined through the patented V3 attachment system. This hardware-free design allows the disc to float both radially and laterally, reducing thermal stress, vibration, and pedal pulsation.

Slotted rotor rings improve bite, shed gases, and enhance pad refresh for consistent stopping power during repeated heavy braking. The directional vane system is turned on both the inner and outer surfaces for superior airflow, maximizing heat dissipation and keeping brake temps under control. Manufactured to extreme tolerances—runout under 0.001" and thickness variation under 0.0003"—the V3 system ensures smooth, stable braking with minimal NVH.

Serviceability is built in: when the rotor ring wears, the hat can be reused, and replacement discs are easily installed thanks to the simplified attachment system. Designed specifically for Porsche 997/991 Turbo applications, this assembly is ideal for track days, endurance racing, and aggressive street driving where heat management and stopping power are critical.
