The Girodisc system is a direct replacement for the OE disc on all 996 GT2/GT3's. 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 21.0 lbs vs. 25.6 lbs for the stock 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.

Girodisc caliper studs are a direct replacement for the OEM caliper bolts.

A must-have item for those who track or race their cars often. The factory bolts will quickly strip out the threads in the expensive wheel uprights, from removing the calipers for maintenance. These Cup-style caliper studs will eliminate this problem and quickly pay for themselves. They also allow for quicker and easier caliper installation by guiding the calipers into position. Manufactured from aerospace quality 17-4 PH stainless steel for high strength and corrosion resistance. One kit includes 4 studs, nuts, and washers, complete for one axle. Two kits are required for the front and rear.
These Brake caliper stud kits now include the highest quality available, ARP 12-point nuts. This is a no-compromise solution. Made from high-strength stainless steel, these nuts will not corrode, have a 180,000 PSI tensile strength, and are compact in size for a better fit in the brake caliper bore.

Please Note
If you are not familiar with, or confident that you understand how to replace the caliper bolts with studs please have a certified mechanic perform the installation.

Brake Disc Type: 2-Piece Slotted

The Girodisc brake rotor is a direct replacement for the OE discs, and provides significant performance benefits. The rotors are compatible with any of the current pads typically used with these cars.

Additional information:

Braking Performance: The rotor is a two-piece design developed in racing to produce a lightweight rotor that can compensate for the different expansion rates between the hat and rotor and eliminate the possibility of rotor warping.

The rotor and hat have a floating mount system, which utilizes 10 high strength alloy steel drive pins, which allows for axial and radial float.

More heat sink without a weight penalty: The Girodisc disc set weights in a little lighter than the OE system but with an important advantage. The rotors have grown in diameter. This means that weight has been transferred from the center hat were it does nothing to the outer diameter where it is actively absorbing and dispersing heat.

High Quality Materials: The Girodisc system uses only the highest quality materials and components. The rotors are high carbon content iron for long wear and stable thermal performance. The top hat section is machined from billet aluminum with an attractive anodized finish. 

This discs will fit cars with the Ceramic option from factory.
