Girodisc is a Braking Technology Company dedicated to developing the best quality high performance braking components and solutions. Girodisc designs and engineers the replacement discs after documenting and studying the OE brake system and specifically the disc design. After analyzing the data and determining how best to maximize the benefit of the new disc, the design process is carried out using 3D CAD-CAE (Computer aided drafting, Computer aided engineering). Prototypes are constructed and tested with a vehicle. When the Girodisc team is satisfied that the disc will meet the goals established for the vehicle, it is produced in limited quantities and released for sale.

Putting lessons learned and the latest technologies together to develop the highest performance braking systems for your project, racing car, or road car is the mission of Girodisc. All this technology has put towards the Audi R8 with some great rotor solutions for both front and rear.

Audi R8 Girodisc Front 380mm 2-piece Rotor Upgrade



The Girodisc system is a direct replacement for the OE disc with the addition of their provided caliper spacers. Their rotor is slightly larger than the OEM rotor at 380mm versus 365mm providing greater braking force and cooling capacity. The Girodisc front rotors are approx 21.95lbs vs. 27lbs for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.



Audi R8 Girodisc Rear 2-piece Rotors



The Girodisc system is a direct replacement for the OE disc. No modifications are necessary. The disc will bolt directly to the car and work with OE calipers perfectly. By upgrading your brakes with lightweight high performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. The Girodisc rear rotors are lighter than the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.


On both systems, the central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is made from cast iron to the same specification and material as used by professional racing organizations. It is 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 10 high strength alloy steel drive pins, manufactured by Girodisc to their 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. 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.

When used with performance pads and hi-temp fluid, you have what amounts to a truly amazing solution to overheating or warping rotors.
