Description

These GiroDisc 2-piece, fully-floating rotors are a direct replacement for the front rotors on the Porsche 997 GT3 Cup factory race cars.

The rotor rings are machined from a proprietary casting made of high-carbon iron formulated to GiroDisc's specifications. This superior metallurgy results in a rotor that better withstands hard use, and the curved vanes act as a centrifugal pump pulling air in through the hub to cool the discs. The 2-piece design has a reusable hat which can be installed onto new rings when they need to be replaced.

All major components including the hats, rotor rings, and drive pins are manufactured in-house at our facility in Bellingham, WA from domestically-sourced materials. The hat is made from 6061-T6 aluminum and coated in a type 3 clear anodize finish. The drive pins are made from a high-strength steel alloy and cadmium-plated for corrosion resistance. All rotors are assembled with spring clips and spring washers for race-ready float while also being street-friendly with no noise from loose hardware.
