Il sistema Girodisc sostituisce direttamente il disco OE su tutte le 996 GT2/GT3. Non sono necessarie modifiche. Il disco si fisserà direttamente all'auto e funzionerà perfettamente con le pinze OE. Aggiornando i tuoi freni con ricambi leggeri e ad alte prestazioni invece di un kit freni di grandi dimensioni, la tua predisposizione di fabbrica viene mantenuta così come l'efficienza dell'ABS. I rotori anteriori Girodisc pesano circa 21,0 libbre contro 25,6 libbre delle unità di serie. Questa riduzione del peso rotazionale e non sospeso consente un'accelerazione e una risposta delle sospensioni più rapide.

La sezione centrale del cappello del nostro rotore è realizzata in alluminio aeronautico 6061-T6 rigorosamente di provenienza statunitense. Il disco è realizzato con la nostra ghisa brevettata, colata negli Stati Uniti e lavorato dall'inizio alla fine presso Girodisc. Il rotore utilizza un design a pale curve, sviluppato nelle corse per fungere da pompa centrifuga per forzare l'aria di raffreddamento attraverso il disco.

Il rotore e il cappello hanno un sistema di montaggio flottante, che utilizza 10 perni di trasmissione in acciaio legato ad alta resistenza, prodotti da Girodisc negli Stati Uniti secondo le nostre specifiche e placcati cadmio per una resistenza alla corrosione di lunga durata. Questi perni assorbono il carico dalle azioni di frenatura mantenendo il gioco assiale e radiale tra cappello e disco. I perni sono fissati mediante viti a testa cilindrica classe 12.9 con rondelle temprate. Per evitare che i rotori facciano rumore quando sono freddi, i perni sono montati con rondelle elastiche antirumore sul lato del rotore che consentono al rotore di crescere con l'espansione del calore ma eliminano il tintinnio e il rumore associati ai rotori flottanti. Questo galleggiante consente inoltre al rotore di autocentrarsi tra le pastiglie.

Una volta installato il sistema Girodisc, è sufficiente sostituire il rotore in ghisa quando necessario.

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.
