Girodisc A1-291 Two-Piece Floating Front Brake Rotors

FITMENT: Porsche Cayman GT4RS (718), Front

This Girodisc system is a direct replacement for the OEM drilled front iron rotors on the Porsche 718 Cayman GT4RS. No modifications are necessary when installing these Girodisc rotors, allowing use of unmodified factory pad shapes (unlike most aftermarket racing rotors for the GT4RS). The Girodisc rotors will bolt directly to the car and work with the excellent OEM Brembo calipers perfectly.

By upgrading your Porsche's brakes with lightweight, high performance Girodisc floating rotors (as opposed to a big brake kit), both the brake bias and ABS actuation dialed in by Porsche engineers are preserved.

The central hat section of each Girodisc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron constructed in the USA, made to the same specification with the same material used by professional racing organizations. The rotors' curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc.

The rotor and hat mount together through a floating mount system which utilizes ten high strength alloy steel drive pins manufactured by Girodisc in the USA to their own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat. The pins are secured by class 12.9 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors.

The two-piece Girodisc design allows for disc-only replacement as well, minimizing future replacement costs and delivering outstanding performance.
