Girodisc A1-220 Front Rotors for F8X with Red, Silver or Gold Calipers
A1-220
Applications:
-F8X M3, M4 including CS with optional carbon ceramic brake package (gold calipers)
-F87 M2, M2 Competition & M2 CS with red or silver calipers
-F87 M2 CS with optional carbon ceramic brake package (gold calipers)
If your vehicle has blue calipers, they require a different size of rotor (A2-186).
Converting from Carbon Ceramic Rotors
Our iron rotors replace the factory carbon ceramic rotors with no modifications necessary. We strongly suggest changing the pads at the same time to a material designed to work with iron rotors.
Background Information
The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from our own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilizes 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 in the USA 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.

Description
The disc is made from cast iron, constructed in the USA and is made 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 8 or 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA 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 grade 12 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.
