Description
 
The Girodisc system is a direct replacement for the OE disc. 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 rear rotors are approx 11lbs vs. 18lbs for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.

The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is made from cast iron to the same specification and material as used by professional racing organizations. It is 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 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. 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.

This rotor is a direct OE replacement but do to the tight space between the rotors hardware and the caliper arching the pad is required for clearance. Please refer to the diagram below showing the required cut line.



If rear pads are purchased from Girodisc or you already have rotors from us and need to replace the pads we will arch them for you before shipping them out.

Once the Girodisc system is in place, simply replace the cast iron rotor when needed.

When used with performance pads and hi-temp fluid, you have what amounts to a truly amazing solution to overheating or warping rotors.
