GiroDisc brake rotors for the Porsche 991.2 GT3 and GT3 RS (2017+) fitted with OEM iron rotors, a lighter alternative to worn factory discs that bolts straight onto the stock calipers with unmodified factory pads. The cast iron disc is poured and machined in-house at GiroDisc in the USA, with a curved vane design that acts as a centrifugal pump to force cooling air through the rotor. A floating hat and disc assembly, secured with 12 cadmium-plated alloy steel drive pins, lets the disc self-centre and expand with heat without rattling or losing its factory brake bias. Front rotors are enlarged to 380mm and come with the caliper spacers needed to fit them; rear rotors stay at OEM size. The factory handbrake is retained throughout.
