The Girodisc brake rotor is a direct replacement for the OE discs, and provides significant performance benefits. The rotors are compatible with any of the current pads typically used with these cars.
Additional information:
Braking Performance: The rotor is a two-piece design developed in racing to produce a lightweight rotor that can compensate for the different expansion rates between the hat and rotor and eliminate the possibility of rotor warping.
The rotor and hat have a floating mount system, which utilizes 10 high strength alloy steel drive pins, which allows for axial and radial float.
More heat sink without a weight penalty: The Girodisc disc set weights in a little lighter than the OE system but with an important advantage. The rotors have grown in diameter. This means that weight has been transferred from the center hat were it does nothing to the outer diameter where it is actively absorbing and dispersing heat.
High Quality Materials: The Girodisc system uses only the highest quality materials and components. The rotors are high carbon content iron for long wear and stable thermal performance. The top hat section is machined from billet aluminum with an attractive anodized finish.

The Zimmermann Formula Z brake disc was designed with the aim of teaming simple installation with optimum braking effect under high mechanical and thermal load.
The compound brake disc developed by Zimmermann accommodates the increased demands incurred by engine tuning and optimised chassis structures.
Your advantages:
• Excellent deceleration action and no distortion of friction ring at high temperatures
• Substantial weight saving and therefore less unsprung mass
• Floating mounting enables radial expansion of the brake disc under relatively heavy loads, thus preventing shielding and increasing resistance to heat cracks
• „Hot spots" prevented by optimised design of ventilation channels
• 1:1 exchange of original disc possible
• Not subject to registration: general ABE certification supplied with disc
• No conversion required for brake tuning

Kit Contains:
Brake Disc complete with centre bell.
Brake Disc Type: 2-Piece Slotted
The Girodisc system is a direct replacement for the OE disc. No modifications are necessary, and it allows the use of unmodified factory pads. The disc will bolt directly to the car and work with factory calipers.
The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from our own proprietary cast iron, poured in the USA and machined from start to finish in-house at Girodisc. The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.
The rotor and hat have a floating mount system, which utilizes 12 high strength alloy steel drive pins, manufactured by Girodisc in the USA to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by class 12.9 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.
Once the Girodisc system is in place, simply replace the cast iron rotor when needed.
This product is a special order item, allow 5 - 7 working days for delivery.

Advanced Carbon Ceramic Technology
At the heart of this braking system are the latest generation 9m carbon ceramic discs, manufactured using long-strand carbon fibre reinforced with silicon carbide. This sophisticated construction delivers extraordinary strength, exceptional wear resistance and industry-leading thermal stability.
Unlike conventional cast iron brake discs, carbon ceramic rotors are capable of maintaining outstanding braking performance even under repeated high-speed stops, making them ideal for spirited road driving, track days and endurance use.
Precision Floating Disc Design
Each rotor features a lightweight two-piece floating design, incorporating centre bells CNC machined from 6061-T6 billet aluminium.
The billet bells are:
- Precision CNC machined.
- Hard anodised for corrosion resistance.
- Exceptionally strong and rigid.
- Lightweight to reduce rotational mass.
- Designed to accommodate thermal expansion during extreme braking.
This floating construction improves braking consistency while reducing stress throughout the braking system.
Why Upgrade to Carbon Ceramic Brakes?
Carbon ceramic braking technology offers significant advantages over traditional cast iron brake systems.
Benefits include:
- Approximately
16kg reduction in unsprung weight compared with cast iron discs.
- Sharper steering response.
- Improved suspension performance.
- Faster vehicle direction changes.
- Increased acceleration due to reduced rotating mass.
- Enhanced ride quality. Improved overall vehicle dynamics.
Reducing unsprung weight allows the suspension to react more effectively to road surfaces, improving grip, handling and driver confidence.
Exceptional Heat Resistance
During repeated heavy braking, conventional steel discs gradually lose efficiency as temperatures increase.
The Ninemeister Carbon Ceramic system is engineered to
withstand:
- High-speed road driving.
- Mountain roads. Fast road touring.
- Repeated track sessions.
- Extreme braking temperatures.
- Sustained high-performance driving.
The carbon ceramic construction delivers outstanding thermal stability, allowing the braking system to provide consistent stopping power without fade, even under the harshest conditions.
Outstanding Durability
One of the greatest advantages of carbon ceramic technology is longevity.
When properly maintained, the discs offer:
- Exceptional wear resistance.
- Outstanding corrosion resistance.
- Potential service life measured in hundreds of thousands of miles under normal road use.
- Reduced maintenance requirements.
- Long-term ownership value.
This makes carbon ceramic brakes an investment that continues to deliver performance throughout the life of the vehicle.
