Product Details

Brand: Performance Friction
Disc type: Two-piece floating slotted iron disc
Disc technology: Direct Drive V3
Disc size: 380 x 34 mm
Position: Front axle
Fitment: Left or right side
Quantity: 1 disc assembly

Vehicle Fitment

Fits the front axle on the following Porsche models:

Porsche 991 GT3 2012 onwards
Porsche Cayman 981 GT4 2014 onwards
Porsche Cayman 718 GT4
Porsche 991 GT3 RS

Important Fitment Notes

This disc assembly is designed to replace the factory steel brake disc setup using 380 mm front discs.

This is not suitable as a PCCB conversion disc.

From the available information, Porsche 981 GT4 and 991 GT3 models equipped with PCCB ceramic brakes use larger 410 mm front and 390 mm rear discs. These assemblies are intended for compatible steel / iron disc applications only.

Performance Friction V3 Technology

PFC’s V3 disc and hat technology has been developed to reduce vibration, brake pulsation and issues caused by thermal expansion under heavy braking.

The patented V3 attachment system uses a retaining ring to secure the disc to the hat, rather than traditional hardware. This allows for faster disc changes, removes the need for torque wrenches during disc replacement and helps reduce overall assembly weight.

The two-turn retaining ring sits within a machined groove in the hat and overlaps the disc flanges, effectively locking the disc and hat together while still allowing the floating disc to perform as intended under heat.

Key Benefits

Two-piece floating iron disc design
Slotted braking surface for improved pad bite and heat management
Direct Drive V3 retaining ring system
Fast and simple disc replacement
Reduced assembly weight compared with older designs
Designed for high-performance road and track use
Excellent consistency under repeated heavy braking
Suitable for centre-lock road wheel applications where compatible

Manufacturing Quality

Performance Friction discs are manufactured to exceptional tolerances for high-speed braking stability and consistency.

Run-out: less than 0.0254 mm
Disc thickness variation: less than 0.00762 mm
Surface finish: less than 0.7 microns

When used with suitable fast road or track day brake pads, these discs can offer improved component life, better consistency and stronger on-track performance compared with many standard replacement options.
