GiroDisc Porsche 911 Carrera (991.2) w/PCCB (Iron Rotor Pad Shape) Slotted Rear Rotors

Upgrade your Porsche’s braking system with Girodisc’s 390mm rear iron rotors, designed as a direct replacement for OEM PCCB (carbon-ceramic) discs. This conversion provides improved heat capacity, consistent braking performance, and drastically lower maintenance costs—all while maintaining factory fitment and ABS compatibility. Each rotor features a CNC-machined 6061-T6 aluminum hat and Girodisc’s proprietary high-carbon cast iron friction rings, all made in the USA. The floating two-piece design allows for controlled expansion under heat, preserving pad contact and consistent pedal feel. The curved vane design acts as a centrifugal pump, pulling cooling air through the disc for maximum thermal efficiency during hard use.
