Girodisc direct replacement lightweight 2 piece brake rotors. 2003+ Viper
Each Girodisc rotors weigh 8.6lbs less than the stock units (34.4lbs for the entire car)!!!
Upgrading brakes with lightweight high performance replacements, maintains factory bias and ABS efficiency. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. The larger rotors provide greater braking force and cooling capacity.
The rotor hat is made from US made 6061-T6 aircraft specification aluminum. The disc is made of 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. No modifications necessary. The disc will bolt directly to the car and work with OE calipers perfectly.
The rotor and hat have a floating mount system, which utilizes 12 high strength alloy steel drive pins, manufactured by Girodisc in the USA 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.
