El sistema Girodisc es un reemplazo directo del disco OE en todos los 996 GT2/GT3. No son necesarias modificaciones. El disco se atornillará directamente al automóvil y funcionará perfectamente con las pinzas OE. Al actualizar sus frenos con reemplazos livianos de alto rendimiento en lugar de un kit de frenos grande, se mantiene su tendencia de fábrica y la eficiencia de su ABS. Los rotores delanteros Girodisc pesan aproximadamente 21,0 libras frente a 25,6 libras para las unidades originales. Esta reducción del peso rotacional y no suspendido permite una aceleración y una respuesta de suspensión más rápidas.

La sección central de nuestro rotor está hecha de aluminio 6061-T6 con especificación aeronáutica estrictamente de origen estadounidense. El disco está hecho de nuestro propio hierro fundido, vertido en los EE. UU. y mecanizado de principio a fin en Girodisc. El rotor utiliza un diseño de paletas curvas, desarrollado en las carreras para actuar como una bomba centrífuga para forzar el aire de refrigeración a través del disco.

El rotor y el sombrero tienen un sistema de montaje flotante, que utiliza 10 pasadores de accionamiento de aleación de acero de alta resistencia, fabricados por Girodisc en los EE. UU. según nuestras propias especificaciones y chapados en cadmio para una resistencia a la corrosión duradera. Estos pasadores absorben la carga de las acciones de frenado mientras mantienen la flotación axial y radial entre el sombrero y el disco. Los pasadores están asegurados mediante tornillos de cabeza clase 12.9 con arandelas endurecidas. Para evitar que los rotores hagan ruido cuando están fríos, los pasadores están montados con arandelas de resorte antiruido en el lado del rotor que permiten que el rotor crezca con la expansión del calor pero eliminan el traqueteo y el ruido asociados con los rotores flotantes. Este flotador también permite que el rotor se centre automáticamente entre las pastillas.

Una vez que el sistema Girodisc esté en su lugar, simplemente reemplace el rotor de hierro fundido cuando sea necesario.

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.
