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 / Rotor Slotted 2-pc FRONT 992 GT3 excl. PCCB SET OF 2




Fits:
Porsche 992 GT3 excl. PCCB

Kit Contains:
Brake Disc complete with centre bell.

Brake Disc Type: 2-Piece Slotted

The Girodisc system is a direct replacement for the OE disc on the 992 GT3 with OEM iron rotors. No modifications are necessary, and it allows the use of unmodified factory pads. The disc will bolt directly to the car and work with factory calipers.

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 12 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.

This product is a special order item, allow 5 - 7 working days for delivery.
