PFC Rear Slotted Replacement Disc V3

Porsche 992 GT3 Cup/718 GT4 RS Clubsport

Dimensions: 380mm diameter, 32mm thickness, 52mm radial depth

Brake disc only, does not include brake hat (fits on OEM hat).

Not for use in official Porsche Carrera Cup championships.

PFC has released their new V3 disc and hat technology. This advanced design features a patented attachment mechanism using a retention ring to hold the hat and disc together. This eliminates the need for torque wrenches, giving you a no-hassle solution to the need for a quick, efficient disc replacement.

In addition to being convenient, PFC's new V3 technology is much lighter than previous designs, reducing unsprung weight on your car.

This V3 disc retention method is based on the use of a two- or three-turn retaining ring, which is held in a groove in the hat that overlaps the disc flanges – effectively locking the disc to the hat.

PFC V3 Disc Features:

• Reduced mass on disc connecting flanges, which reduces thermal distortion (more specifically, coning) at race temperatures. Reduced coning allows the pads to sit flatter on the disc, which better utilizes the available radial depth. There is better pad force distribution and the brakes will run cooler, reducing hot spots on the disc. This will also have the benefit of reduced taper wear of the pads.
• More heat will be contained in the brake faces because there is less of a heat sink in the flanges. This reduces thermal stress at the ID of the disc and reduces the chance of thermal cracking to occur.
• Consistent disc float from race beginning to end. As a race progresses with a bobbin disc, float will often be reduced when a bobbin is no longer sitting square in the disc. Reduced float will increase piston knockback, increase pedal travel and add vibration.
• Reduced complexity. The number of brake assembly parts is reduced from 38+ for a bobbin drive disc to just 3 in a V3 disc assembly
• Decreased assembly time. You can assemble a V3 race disc in a matter of seconds.
