Audi B5 S4/C5 A6/Allroad Girodisc Front 345mm Front 2-piece Rotors with Brembo 6 Piston Caliper (A1-120)

$752.00 Set of 2

$800.00

These are lightweight two piece rotors that are made specifically to be used on the B5 S4 or C5 A6/Allroad with the OEM "18Z" Brembo 6 piston caliper found on the Porsche Cayenne, Audi Q7, and VW Touareg.  The only modification required is some minor clearancing on the bottom of the upright. We provide instructions and a video on how to do this. Other than that the discs will bolt directly to the car and work with the "18Z" calipers perfectly. The Girodisc front rotors weight 19.5lbs which are lighter than the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. 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 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. 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.Sold/priced in pairs.*These rotors only fit the B5 S4, C5 A6s and Allroads with the 2.7TT motor. This kit will not fit C5 A6s, RS6s, or Allroads with the 4.2L V8.

Girodisc is a Braking Technology Company dedicated to developing the best quality high performance braking components and solutions.    Girodisc is guided under the direction of company Principal Martin Meade, who spent five years as an Engineer with Porsche Engineering Services, where he played a role in developing current Porsche technology. Martin began his engineering career working in Aerospace, developing tools and components for special projects. Before working with Porsche, Martin learned a great deal about vehicle design and technologies by working with several vehicle design and development firms. Martin has developed a critical eye and will not accept anything but the best quality.   Martin has enlisted help from key sources such as a former Road Testing engineer and Design Engineer for Brembo North America in the High Performance division, Eric Dahl. With lessons learned at Brembo, and experience in prototype and racing car design, Eric has developed a broad spectrum of engineering capabilities in the world of high performance automobiles, and specifically the technologies for developing braking systems. 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.
