Uncompromising Performance for Your Porsche 991

For the Porsche 911 GT3, GT3RS, and GT2RS (991 chassis) owner, braking is just as important as acceleration. GiroDisc slotted rear rotors are engineered to provide the ultimate in thermal management and durability for your high-performance machine. These rotors are specifically designed for vehicles without PCCB (Porsche Ceramic Composite Brakes), offering a superior alternative for track enthusiasts and performance drivers.

Engineered for the Track

GiroDisc rotors are built to handle the intense heat generated during high-speed track sessions. The slotted design effectively dissipates heat and removes surface gases, ensuring that your brake pads maintain optimal contact with the rotor surface. This results in shorter stopping distances, improved pedal modulation, and reduced brake fade, allowing you to drive with total confidence.

  • Compatible with 991 GT3, GT3RS, and GT2RS (Excl. PCCB)
  • Advanced slotted surface for maximum heat dissipation
  • High-performance iron alloy for durability
  • Precision-engineered for factory caliper fitment
  • Ideal for track-focused Porsche owners

When every millisecond counts, rely on the precision of GiroDisc. These rotors are the gold standard for those who demand the best from their Porsche 911. Elevate your driving experience with high-quality components from GGCRACING.
