- Porsche 996 C4S 3.6L 09/01-2005
- Porsche 996 TURBO 2000-05
350mm brake discs and caliper spacer kit complete with anti vibration dampers and sensors.
Fits:
Porsche 996 C4S 2001-2005
Porsche 996TT 2001-2005
- The Porsche 996 Turbo and C4S upgrade to 350mm brake discs is a performance enhancement specifically designed for these Porsche models.
- This upgrade involves replacing the stock brake discs with larger 350mm discs, increasing the surface area for improved braking performance.
- The larger discs provide more contact area for the brake pads, resulting in better heat dissipation and reduced brake fade during intense driving conditions.
- The upgrade also enhances braking power, allowing for shorter stopping distances and improved overall braking performance.
- This brake upgrade is highly beneficial for those who enjoy spirited driving, track days, or want to enhance the overall performance and safety of their Porsche.
- It is important to ensure proper fitment and compatibility before purchasing and installing this upgrade for your specific Porsche model.

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:
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.
