GiroDisc Front 2-Piece Floating Rotor Pair for B5 Audi S4 with Brembo 18Z 6-Piston Caliper
034Motorsport is proud to offer this GiroDisc 2-Piece Performance Floating Front Rotor Upgrade for the B5 Audi S4 with Brembo 18Z 6-Piston Caliper!
These lightweight, 2-Piece rotors are specifically designed to be used on the B5 Audi S4 with the OEM 18Z Brembo 6-Piston Calipers found on the Porsche Cayenne, Audi Q7, and Volkswagen Touareg. Slight clearancing is required to the bottom of the upright for proper fitment. The GiroDisc rotors weigh 19.5 lbs each vs. the 22.0 lb factory B5 S4 rotors. That's a 2.5lb reduction per corner! This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.
The central hat portion of the GiroDisc rotor is made strictly from U.S. sourced 6061-T6 aircraft specification aluminum. The disc is constructed from GiroDisc's own proprietary cast iron, poured in the USA and machined from start to finish in-house at their facility. 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 that utilizes 8 or 10 high strength alloy steel drive pins, manufactured by GiroDisc in the USA to their own specifications and cadmium plated for a long lasting corrosion resistance. The pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by Grade 12 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.
