Girodisc Front 2-piece rotors for Audi B5 S4 with Brembo '18Z' 6 Piston Caliper

€ 968,00

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.

Sold/priced per pair.

These are lightweight two piece rotors that are made specifically to be used on the B5 S4 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 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 10 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. 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.***
