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. The Girodisc front rotors are approx 16.5 lbs vs. 20.5 lbs for the stock front units and approx 11 lbs vs. 18 lbs for the stock rear 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.
Please note for rear applications:
The Girodisc system is a direct replacement for the original disc however the OEM pads along with some aftermarket brake pads will need to be modified before installation to work with our assemblies. This modification is necessary to accommodate the hardware arrangement of our two-piece discs and still retain the OEM parking brake and simply requires the backing plate of the brake pad to be ground down to match the arc of the pad material. A disclaimer and instructions for this modification are included with the discs. All brake pads sold by Girodisc for this application have already been modified on our CNC equipment for a plug and play solution.
