Not suitable for PCCB (Porsche Ceramic Composite Brake) conversions.
Designed as a direct replacement for vehicles equipped with 350mm steel rear brake discs, including centre-lock wheel configurations.
Each assembly consists of a precision-machined aluminium hat paired with a high-carbon cast iron rotor ring, providing optimal heat management and reduced unsprung weight.
What This Brake Disc Kit Does
Brake discs convert kinetic energy into heat during braking. This upgraded system improves heat dissipation and braking consistency under load.
It helps:
• Improve braking performance and consistency
• Enhance heat dissipation during repeated braking
• Reduce brake fade under high temperatures
• Improve pedal feel and braking response
• Increase durability compared to standard discs
Advanced Two-Piece Floating Design
The floating disc construction allows the rotor ring to expand independently from the hat under heat, reducing stress and preventing distortion.
Key benefits include:
• Reduced risk of warping under heavy braking
• Improved thermal stability
• Minimized vibration and brake judder
• Enhanced performance during repeated braking cycles
High-Performance Materials & Engineering
CM-250 High Carbon Alloy Cast Iron Rotors
Manufactured using a formulated high carbon alloy for increased strength,
durability and heat resistance.
72 Cooling Vanes
Internal vane design maximises airflow through the disc, significantly
improving cooling efficiency.
Heat-Treated Rotor Rings
Stress-relieved during manufacturing to prevent deformation and vibration under
extreme conditions.
CNC Machined 6061-T6 Aluminium Hats
Lightweight yet strong, precision machined and hard anodised for corrosion
resistance and durability.
Slotted Disc Surface
Improves pad bite, helps remove gases and debris, and enhances braking
performance in all conditions.
Key Specifications
• Disc Type: 2-piece floating slotted
• Disc Size: 350mm x 28mm
• Cooling: 72 vane internal design
• Construction: High carbon iron rotor with aluminium hat
Why Upgrade Your Porsche 992 Brake Discs
Factory brake discs are designed for general road use. Under performance driving, they can suffer from heat build-up, fade and reduced efficiency.
Upgrading to a two-piece floating system provides:
• Better cooling and heat management
• Increased resistance to brake fade
• Reduced unsprung weight
• Improved braking consistency under load
• Longer service life under demanding conditions

Please note: Those discs are not sided. They fit left or right side of the car. Brake disc rotors are priced each.
The Zimmermann Sport Brake Disc was developed as a result of experience of brake discs in series-production vehicles in connection with racing. The brake system is optimised by combining high-quality cast materials with a perforated braking surface.
Your advantages:
• Better wet braking performance by permanent expulsion of brake dust and water
• Sporty look
• Because of the anti-corrosion protection Coat Z better finish - especially of the hub and the outer diameter
• Noticeable improvement in the braking power of your car
• Prevention of brake fade
• Countersinking of holes doubles up as wear indicator
• 1:1 exchange of original disc possible
• No additional adaptions necessary
• Not subject to registration: general ABE certification supplied with disc
