McLaren 570S/570GT/540C/650S/MP4-12C GiroDisc Iron Rotor Conversion Kits
Upgrade the factory brakes or replace worn out rotors with premium GiroDisc brake rotors. Perfect for track use and a cost effective premium brake replacement solution vs CCM. 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 10 high strength alloy steel drive pins, manufactured by Girodisc to the highest 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. 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. FEATURES: Fits all 570S / 570 GT / 540 C / 650S / MP4-12C with CCM Rotors Rear rotors are OEM size Perfect solution for vehicles seeing track use - saving you from costly OE ceramic replacements Direct factory replacement - no modifications necessary Cadmium plated for long lasting corrosion resistance Increased rotor life Greater cooling efficiency Retains factory e-brake Premium grade; made in U.S.A. IMPORTANT NOTE When converting from carbon ceramic brakes to GiroDisc iron rotors we STRONGLY recommend replacing all four rotors in order to maintain the factory brake bias and controlled braking in all driving conditions.
