High-Performance Braking for Your Porsche 991

Elevate your track performance with GiroDisc 2-piece slotted rear rotors, specifically engineered for the Porsche 991 GT3, GT3RS, and GT2RS models originally equipped with PCCB (Carbon Ceramic) systems. These rotors are designed to utilize the iron rotor pad shape, providing a seamless transition for drivers looking to replace expensive ceramic components with a more durable, track-ready iron solution.

Precision Engineering

GiroDisc rotors feature a center hat made from 6061-T6 aircraft-grade aluminum, hard-anodized for extreme durability. The rotor ring is cast from high-strength iron, ensuring superior thermal capacity and resistance to warping under intense heat. The slotted design effectively clears debris and gases, maintaining consistent pad bite during high-speed braking.

  • Direct replacement for PCCB iron-conversion setups
  • 6061-T6 aluminum center hats for reduced unsprung weight
  • Floating mount system prevents rotor binding
  • High-strength iron rings for maximum heat dissipation
  • Precision-machined slots for optimal pad cleaning

These rotors are the gold standard for enthusiasts who demand reliability on the track without sacrificing stopping power. Whether you are attacking apexes or navigating technical circuits, the GiroDisc system delivers the confidence you need. Experience the ultimate in braking technology and find your next performance upgrade at GGCRACING.
