Girodisc 系统可直接替换所有 996 GT2/GT3 车型的原厂刹车盘，无需任何改装。该刹车盘可直接安装到车辆上，并与原厂卡钳完美兼容。与安装大型刹车套件不同，使用轻量化高性能刹车盘升级刹车系统，可以保持原厂的制动力分配和 ABS 的效率。Girodisc 前刹车盘的重量约为 21.0 磅，而原厂刹车盘的重量约为 25.6 磅。旋转质量和非簧载质量的降低，有助于提升加速性能和悬挂响应速度。

我们转子的中央帽状部分采用美国产6061-T6航空级铝材制成。转子盘片则采用我们自主研发的铸铁，在美国浇铸成型，并在Girodisc公司内部完成从设计到加工的全部工序。转子采用源自赛车技术的弧形叶片设计，利用离心泵的作用将冷却空气强制吹过转子盘片。

转子和盘帽采用浮动式安装系统，该系统使用10个高强度合金钢驱动销，这些驱动销由美国Girodisc公司根据我们的规格制造，并经过镀镉处理，具有持久的耐腐蚀性。这些驱动销承受制动载荷，同时保持盘帽和转子之间的轴向和径向浮动。驱动销通过12.9级螺钉和硬化垫圈固定。为了防止转子在冷态下产生噪音，驱动销在转子侧安装了防噪音弹簧垫圈，这些垫圈允许转子随热膨胀而伸缩，同时消除浮动式转子常见的抖动和噪音。这种浮动设计还使转子能够在刹车片之间自动居中。

Girodisc系统安装完毕后，只需在需要时更换铸铁转子即可。

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.
