These are lightweight two piece rotors that are made specifically to be used on the 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.
Features
- The Girodisc front rotors weigh 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
