Girodisc 390/380mm Front 2-Piece Rotors for R35 Nissan GT-R
Girodisc 390/380mm Front 2-piece rotors for R35 Nissan GT-R:
The Girodisc system is a direct replacement for the OE disc on both CBA(380mm) and DBA(390mm) vehicles.
If your GT-R is a CBA (07-11′) then you’re going to want to choose the 380mm rotors from the drop down menu
If your GT-R is a DBA (12’+) then you’re going to want to choose the 390mm rotors from the drop down menu
The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is made from cast iron to the same specification and material as used by professional racing organizations. It is 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 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.
When used with performance pads and hi-temp fluid, you have what amounts to a truly amazing solution to overheating or warping rotors.
