GiroDisc Porsche 911 GT3/GT3RS/GT2RS (991/992) w/PCCB (Iron Rotor Pad Shape) Slotted Rear Rotors

GiroDisc two-piece rotors are a direct replacement for the factory disc and work with the OE calipers. They cut unsprung weight while keeping the factory brake bias and ABS behaviour. The hat is U.S.-sourced 6061-T6 aluminum, and the ring is GiroDisc's own cast iron, poured in the USA and machined in-house, with a curved-vane design that pumps cooling air through the disc.
