Girodisc Front 2pc Rotors.
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.

- If your car is equipped with carbon ceramic brakes, please see (REF: A1-220)
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.

The GiroDisc 2-piece rotor system is a direct replacement for the OE rotor, no modifications are necessary. The disc will bolt directly to the car and work with OE calipers perfectly. Once the Girodisc system is in place, simply replace the cast iron rotor ring when needed. The average Girodisc 2-piece rotor is approx 2kg lighter per rotor then the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.
