Direct Replacement Advantages
The Girodisc system is a direct substitute for the OE disc, requiring no modifications. These rotors attach directly to your car and integrate flawlessly with OE calipers. Upgrading to these lightweight, high-performance rotors ensures factory bias and ABS efficiency are maintained.
Central Hat Section
Crafted from U.S. sourced 6061-T6 aircraft specification aluminium.
Disc Material
Proprietary cast iron, poured in the USA and fully machined in-house at Girodisc.
Design
Curved vane design, developed from racing technology, acts as a centrifugal pump to enhance cooling air flow through the disc.
Floating Mount System
Utilises 10 high-strength alloy steel drive pins (manufactured by Girodisc) with cadmium plating for corrosion resistance. These pins bear the braking loads while preserving axial and radial float between the hat and disc. Pins are fastened by class 12.9 cap screws with hardened washers.
Anti-Noise Technology
Pins are mounted with anti-noise spring washers on the rotor side to permit heat expansion without noise. This feature also allows the rotor to self-centre between the pads.
Maintenance
Once the Girodisc system is installed, simply replace the cast iron rotor when necessary. Sold/priced per pair.
