Fast Road / Trackday Front Brake Disc & Pad Package 

A complete front braking upgrade combining 9M two-piece floating slotted iron brake discs with matching 9M fast road and trackday brake pads.

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

Developed for demanding road driving and track use, this package combines improved disc cooling and thermal management with a high-friction, fade-resistant brake pad compound. The result is increased stopping performance, consistent pedal feel and greater resistance to the high temperatures generated during repeated heavy braking.

Not compatible with Porsche Ceramic Composite Brake (PCCB) discs.

What Does the Package Include?

The package combines:

  • Two-piece floating front brake disc assemblies
  • Slotted high-carbon iron rotor rings
  • CNC-machined aluminium bells/hats
  • 9M fast road / trackday front brake pads

The discs and pads have been selected to work together as a performance-focused braking package for fast-road, trackday and competition applications.

Two-Piece Floating Front Brake Discs

The 9M front discs use a two-piece floating construction with a high-carbon cast iron friction ring mounted to a lightweight aluminium bell.

The floating arrangement allows controlled movement between the rotor and bell as temperatures increase, helping accommodate thermal expansion and reduce stress within the disc assembly.

Benefits include:

  • Improved thermal management
  • Reduced risk of heat-related distortion
  • Reduced tendency towards brake vibration
  • Consistent performance during repeated heavy braking
  • Lightweight aluminium centre bell
  • Improved cooling compared with conventional disc designs

72-Vane Cooling System

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

This increased airflow helps dissipate heat generated under braking, making the system particularly suited to repeated high-speed stops during spirited road driving and track use.

CM-250 High-Carbon Iron Rotors

The rotor rings are manufactured from CM-250 formulated high-carbon alloy cast iron, providing strength and durability at elevated operating temperatures.

Each rotor ring is heat treated to relieve internal material stresses, helping maintain dimensional stability and reduce the possibility of deformation and vibration through repeated heating and cooling cycles.

CNC-Machined Aluminium Bells

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

The aluminium construction also helps reduce rotating and unsprung mass compared with an equivalent one-piece iron disc.

9M Fast Road / Trackday Brake Pads

The package includes 9M performance front brake pads developed to complement the upgraded iron discs.

The low-metallic, resin-bonded friction material contains steel and aramid fibres and provides a high coefficient of friction of approximately 0.55.

The compound combines strong stopping power with excellent modulation, predictable release characteristics and high resistance to brake fade.

Fast Road & Trackday Performance

During repeated heavy braking, conventional road pads can exceed their optimum operating temperature and begin to lose effectiveness.

The 9M compound is designed to maintain consistent braking characteristics throughout its effective temperature range, providing a solid and predictable pedal feel during demanding driving.

Benefits include:

  • High coefficient of friction – approximately 0.55
  • Increased stopping performance
  • Excellent fade resistance
  • Consistent braking at elevated temperatures
  • Good pedal modulation
  • Predictable brake release
  • Solid pedal feel
  • Excellent pad and rotor life
  • Suitable for fast-road driving
  • Suitable for high-speed trackdays and competition use

Important PCCB Information

This brake disc and pad package is not compatible with Porsche Ceramic Composite Brake (PCCB) discs.

It is intended for vehicles using the appropriate iron/steel braking configuration. Always confirm the brake system fitted to the vehicle before ordering.

Fast Road and Track Brake Upgrades

For Porsche GT models used for fast-road driving and trackdays, upgrading the front discs and pads together provides a more complete approach to improving braking performance.

The 9M package combines floating high-carbon iron discs with a high-friction pad compound, improving heat management, fade resistance, pedal consistency and stopping performance during repeated hard braking.

It is particularly suited to Porsche 996 GT2, 996.2 GT3, 997 GT3 and GT3 RS owners looking for a matched front brake upgrade for performance road driving, trackdays and competition use.

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 discs will fit cars with the Ceramic option from factory.

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.

About SPORTS Brake Disc

Experience race-inspired stopping power with Porsche sports brake discs from Design911. Designed for performance driving, these upgraded brake rotors provide greater heat dissipation, improved bite, and enhanced fade resistance, ensuring confidence under even the most demanding conditions.

What They Are & What They Do
Sports brake discs (or rotors) are precision-engineered components that work with brake pads to generate friction and stop the car effectively. Unlike standard discs, sports variants are often drilled, grooved, or slotted, helping to vent heat and gases, improve braking response, and maintain consistent performance during high-speed or repeated stops.

Why They Fail
Over time, brake discs wear down from heat cycles, friction, and corrosion. Common signs of failure include scoring, warping, cracking, or vibration during braking. Track use or aggressive driving can accelerate wear, while low-quality discs may develop hotspots and fade under stress.

Why They Should Be Replaced
Replacing worn or damaged brake discs restores optimal braking efficiency, pedal feel, and vehicle control. New sports discs not only improve performance and safety but also extend pad life and reduce fade, ensuring Porsche’s legendary stopping precision. Design911 offers genuine Porsche discs for factory performance and aftermarket upgrades for enhanced durability and responsiveness.

Whether you’re restoring a classic 911 or tuning a Cayman or Taycan for track use, our range of sports discs combines precision, reliability, and performance to keep your Porsche braking like new.

Aftermarket Performance Brake Discs
High-quality aftermarket discs featuring slotted or drilled designs for superior airflow, reduced fade, and consistent friction performance.

Front Sports Brake Discs
Heavy-duty front rotors built to handle intense braking loads, offering maximum stopping power and stability under pressure.

Rear Sports Brake Discs
Rear discs designed for balanced braking and improved heat management, ensuring control and composure under repeated deceleration.

Drilled & Grooved Brake Rotors
Advanced rotors engineered to dissipate heat, clean brake pads, and deliver responsive braking for track and fast-road applications.

Motorsport & Track Brake Discs
Race-grade rotors made from high-carbon or composite materials, offering unmatched durability and thermal control for competition use.
