GiroDisc Audi R8, Lamborghini 394mm Front Iron Rotor Conversion, incl. caliper spacers

The Girodisc iron rotor conversion is a direct replacement for the OE carbon ceramic disc with the addition of our provided caliper spacers.  Our rotor is slightly larger than the OEM rotor at 394mm versus 380mm. 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 or
