PRODUCT DESCRIPTION

Girodisc A2-155 Two Piece Floating Racing Brake Rotors

These Rotors Fit The Following Cars (w/ OEM Steel Rotors):

  • Porsche 981 Cayman GT4 Rear
  • Porsche 718 Cayman GT4 Rear
  • Porsche 991 Turbo/Turbo S Rear

This Girodisc system upgrades your Porsche OEM rear brakes to 380mm two-piece steel discs and aluminum hats. This two-piece floating rotor design will bolt directly to your Porsche GT4 or Turbo and work flawlessly with the OEM calipers using the included machined aluminum spacers. Especially when paired with the Girodisc A1-066 front Porsche rotors , upgrading your brakes to lightweight, high-performance Girodisc rotors, you maintain the factory brake bias and ABS effectiveness. Much lighter than the OEM rotors, Girodisc rotors reduce rotational and unsprung mass giving you stronger braking and faster suspension response.

Combined with Pagid or PFC racing brake pads and Thunderhill Performance RF1 racing brake fluid, Girodisc rotors are the ultimate solution to overheated, cracked OEM Porsche rotors that result from high-performance driving. The central hat of the rotor is made from 6061-T6 aircraft aluminum. The disc is manufactured in the USA from the same cast iron used by professional racing organizations. Its curved-vane design, developed in racing, acts like a centrifugal pump forcing cool air through the disc.

The disc and hat mount together through a floating mount system using ten cadmium plated, high-strength alloy steel drive pins manufactured by Girodisc. These drive pins transfer braking load while maintaining axial and radial float between the disc and hat to allow for heat expansion. Anti-noise spring washers eliminate the noise typically associated with floating rotors.

This two-piece Girodisc design allows for disc-only replacement, reusing the hat to minimize maintenance costs.
