GiroDisc
GiroDisc manufactures premium two-piece floating brake rotors designed for performance street and track applications where reduced unsprung weight, superior thermal management, and consistent pedal feel under repeated hard braking are required. The two-piece design separates the cast iron friction ring from the aluminum hat using a patented floater system that allows the rotor to expand thermally without transmitting warping stress to the hub, eliminating the judder and pedal pulsation that single-piece rotors develop after repeated track sessions. GiroDisc rotors are available for a wide range of European and Japanese sports cars including Porsche, BMW M, Ferrari, Lamborghini, and the Subaru WRX, targeting enthusiasts and racers who demand the same engineering quality in their brake hardware as in their suspension and engine components. The significant weight reduction compared to equivalent cast iron rotors improves both acceleration and braking response by reducing the rotational...
