Girodisc A2-159 2-Piece Slotted Rear Brake Rotor Upgrade, 15-21 McLaren 570S/570GT w/CCM

Description

Upgrade the braking performance of your 15-21 McLaren 570S/570GT w/CCM with Girodisc 2-piece Brake Rotors A2-159.

The Girodisc system is a direct replacement for the OE CCM disc. No modifications are necessary; the disc will bolt directly to the car and work with the original calipers without issue.

The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc itself is made from cast iron to the same specification and material used by professional racing organizations. It features 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 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. To keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side, allowing the rotor to grow with heat expansion while eliminating 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, this system provides a truly exceptional solution to overheating or warping rotors.
