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.

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.

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.

This is a 340mm Upgrade with spacers & hardware
Porsche 981 Boxster base model
Porsche 981 Cayman base model
Kit Contains:
Brake Disc 340MM complete with centre bell.
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. The rotor rings are bright zinc plated to help prevent unsightly corrosion
This product is a special order item, allow 5 - 7 working days for delivery.
