Brake Disc Type: 2-Piece Slotted

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. 

This product is a special order item, allow 5 - 7 working days for delivery.

Porsche 997 GT3 Cup Car

Kit Contains:
Brake Disc 380 complete with centre bell.

Brake Disc Type: 2-Piece Slotted

The Girodisc system is a direct replacement for the OE disc on all 997.2 GT3/GT2's, with or without the OEM PCCB rotors. No modifications are necessary, allows use of factory unmodified pads unlike most aftermarket solutions for this application. The disc will bolt directly to the car and work with OE calipers perfectly. By upgrading your brakes with lightweight high performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency.

The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from our own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.

The rotor and hat have a floating mount system, which utilizes 12 high strength alloy steel drive pins, manufactured by Girodisc in the USA to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by class 12.9 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.

Once the Girodisc system is in place, simply replace the cast iron rotor when needed.

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 MK1 GT2 2007-09
• Porsche 997 MKII GT3 / GT3 RS 2010-11
• 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.
