The Girodisc brake rotor is a direct replacement for the OE discs, and provides significant performance benefits. The rotors are compatible with any of the current pads typically used with these cars.

Additional information:

Braking Performance: The rotor is a two-piece design developed in racing to produce a lightweight rotor that can compensate for the different expansion rates between the hat and rotor and eliminate the possibility of rotor warping.

The rotor and hat have a floating mount system, which utilizes 10 high strength alloy steel drive pins, which allows for axial and radial float.

More heat sink without a weight penalty: The Girodisc disc set weights in a little lighter than the OE system but with an important advantage. The rotors have grown in diameter. This means that weight has been transferred from the center hat were it does nothing to the outer diameter where it is actively absorbing and dispersing heat.

High Quality Materials: The Girodisc system uses only the highest quality materials and components. The rotors are high carbon content iron for long wear and stable thermal performance. The top hat section is machined from billet aluminum with an attractive anodized finish.

Two-Piece Floating Front Brake Disc – 350 x 34mm
Sold as a pair

High-performance two-piece floating front brake disc upgrade for Porsche 996.2 GT3, GT3 RS and GT2, plus Porsche 997 GT3 and GT2 models.

Fits:

• Porsche 996 GT2 2001-05
• Porsche 996 GT3 MKII 2003>>
• Porsche 996 GT3 RS 2003-04
• Porsche 997 MK1 GT3 / GT3 RS 2007-09

• Porsche 997 MKII GT2 RS 2011-13

Designed for demanding road and performance use, the 9M floating disc combines a high-carbon cast iron slotted rotor with a lightweight CNC-machined aluminium bell. The two-piece floating construction allows the rotor to expand more freely as temperatures increase, helping reduce heat-related stress and the risk of distortion.

Why Upgrade to a Two-Piece Floating Brake Disc?

High-performance Porsche braking systems generate considerable heat, particularly during repeated heavy braking.

A floating disc allows controlled movement between the iron rotor and aluminium bell as temperatures change. This helps accommodate thermal expansion and reduces stress within the assembly compared with a rigid one-piece design.

Benefits include:

• Improved management of thermal expansion
• Reduced heat transfer into the centre bell
• Lower risk of heat-related distortion and vibration
• Consistent braking during repeated heavy use
• Lightweight aluminium bell construction
• Replaceable rotor-ring design
• Suitable for performance road use

72-Vane Cooling Design

Each rotor incorporates 72 internal cooling vanes designed to efficiently move air through the disc.

Improved airflow helps dissipate heat generated during braking, assisting with temperature control during repeated high-speed stops and demanding driving.

CM-250 High-Carbon Iron Rotors

The rotor rings are manufactured from CM-250 formulated high-carbon alloy cast iron, selected for its strength and durability at elevated braking temperatures.

The rotor rings are also heat treated to relieve internal stresses within the material. This helps improve dimensional stability and reduces the likelihood of deformation and vibration through repeated heating and cooling cycles.

Slotted Rotor Surface

The slotted friction surface is designed for high-performance road applications.

Slots help maintain a clean contact surface between the brake pad and disc while allowing gases, dust and debris to escape from the braking surface, promoting consistent pad-to-disc contact.

CNC-Machined Aluminium Bells

The centre bells are CNC machined from 6061-T6 aluminium before being hard anodised for additional surface protection and durability.

Using aluminium for the centre bell also helps reduce unnecessary rotating and unsprung mass compared with an equivalent all-iron construction.

Disc Dimensions

• Diameter: 350mm
• Thickness: 34mm

Porsche 996 GT3 / GT2 & 997 GT3 / GT2 Floating Front Brake Discs

Two-piece floating brake discs are an excellent upgrade for high-performance Porsche braking systems where heat management, durability and consistent braking performance are priorities.

The 9M 350x34mm floating front brake disc combines a high-carbon iron friction ring with a lightweight 6061-T6 aluminium bell and 72-vane internal cooling design. This makes it particularly suitable for Porsche GT3, GT3 RS and GT2 models subjected to enthusiastic road driving and repeated high-temperature braking.

For owners searching for Porsche 996 GT3 brake upgrades, 997 GT3 floating front discs or replacement two-piece GT2 brake rotors, the 9M system provides a performance-focused alternative to conventional brake disc construction.

Ever since the disc brake was invented vibration and pulsation caused by thermal expansion has been a major issue giving rise to warped discs - until now?

PFC has released new V3 disc and hat technology. The advanced design features a patented attachment design that uses a retention ring that holds the hat and disc together.

The ring means no need for torque wrenches, and no hassle. The ability to change a disc quickly and efficiently saves time and effort. As well as being convenient, the new V3 technology is much lighter than previous designs, making it easier to put on and pull off, and making the vehicle lighter.

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

● Exceptional manufacturing standards - Run out less than 0.0254mm, Thickness variation less than 0.00762mm. Surface finishes less than .7 microns.When used in conjunction with Z rated fast road/track day pads, component life and on track performance markedly improved over competitors pads.
