Fabspeed Porsche 991 GT3 GiroDisc Brake Rotors
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 PCCB. The central hat section of each rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from 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 larger rotors are greater heat sinks resulting in increased performance on the track, a reduction in brake fade, and improved brake component life. 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.
