The Formula:R product line is the result of collaboration with the Zimmermann-sponsored racing team. Formula:R composite brake discs sometimes replace very expensive carbon-ceramic brake systems and are intended exclusively for use on the racetrack.
The composite technology with a light metal pot results in a significant weight reduction. This weight reduction leads to a clearly improved driving performance, since the brake discs are part of the unsprung mass. The ratio of unsprung to sprung mass is thereby increased in favor of the sprung mass. The traction and thus the control over the vehicle are noticeably improved.
Your advantages:
• Proven in racing
• Specially coated light metal pot and high-carbon cast friction ring with optimal thermal conductivity
• Highest performance of the disc even when it is temporarily hot
• Optimal ventilation and maximum stability thanks to sloping ribs in the ventilation channel
• Partly as a replacement for carbon-ceramic brake discs
• Free radial expansion through social connection of pot and friction ring
• Brake fading is avoided
• Sporty look with Z-grooves
• Developed exclusively for the race track

Zimmermann Formula:R Racing Brake Disc
The Zimmermann Formula:R racing brake disc range is the result of close collaboration with a Zimmermann-sponsored racing team. Developed specifically for circuit use, these composite discs are designed to deliver stable, repeatable braking on track-driven Porsche models and can, in some applications, be used as an alternative to very costly carbon-ceramic systems.
The discs use composite technology with a light metal hat and a high-carbon cast friction ring. By saving weight in the brake assembly – part of the unsprung mass – they contribute to a more agile, responsive feel from the chassis. Reducing unsprung weight helps the suspension follow the track surface more effectively, which can support traction and driver confidence in demanding race conditions.
Your advantages with Zimmermann Formula:R include a specially coated aluminium pot for a clean, durable appearance, and a friction ring engineered for high thermal capacity and efficient heat flow under sustained use. Internal ventilation with angled ribs is designed for optimal airflow and stability at temperature, while the distinctive Z-groove face design gives a purposeful, motorsport look and helps maintain a consistent disc surface when used with suitable racing pad compounds. These discs are developed exclusively for the race track and are not intended for everyday road use.

When should you review or replace your Porsche formula:r racing brake disc?
On track-driven Porsche models running Formula:R components, it is important to check disc condition regularly so you can spot cracking, heat damage or loss of thickness before it compromises consistent braking feel or leads to component failure. Racing discs work in a very demanding environment and should be inspected more frequently than road hardware.
- Road discs may crack or lose performance when used at racing temperatures, making dedicated racing discs such as Formula:R a more appropriate choice for circuit use.
- Visible heat checking, cracking around drill points or at the outer edge, blue or heavily burnt surfaces, or discs approaching minimum thickness indicate that replacement should be considered.
- If you change to a different pad compound, tyre or suspension setup for racing, reviewing the discs at the same time helps maintain overall balance and consistency.
- Any vibration, pulsing, or noticeable change in pedal feel under repeated hard use on track is a cue to inspect discs, pads and hubs and replace parts where necessary.
If any of these apply, it is a good time to review your Formula:R racing brake disc and replace anything that is past its best so your Porsche stays dependable and reassuring to drive on the circuit.
