Lightweight GiroDisc two-piece floating front rotors for the Audi S4 / A4 / A6 / Allroad with the OEM Brembo 18Z six-piston caliper (as found on the Porsche Cayenne, Audi Q7 and VW Touareg). The discs work with the 18Z calipers, and the reduced rotational and unsprung weight allows quicker acceleration and suspension response.
