GiroDisc Porsche 911 Turbo (997) w/PCCB / Cayman GT4 (981/982 Excl PCCB) Slotted Front Rotors
GiroDisc slotted front rotors provide direct replacement braking for Porsche 911 Turbo (997) models with PCCB and Cayman GT4 (981/982 excluding PCCB). The two-piece design with high carbon rotors and aluminum hats reduces unsprung weight by 25% for sharper handling. Slotted surfaces clear debris and gases while curved vanes manage heat for track-ready stopping power.
Key Features
- Slotted Rotor Faces: Channels water gases and pad residue away from the surface for immediate bite in wet dry or high-heat conditions
- 72 Curved Vanes: Direct airflow through the rotor core to pull heat away and maintain pad temperatures during repeated hard stops
- Two-Piece Construction: 6061-T6 aluminum hats save 25% weight over OEM PCCB rotors (21.5 lbs each vs 28.6 lbs) to improve suspension response
- High Carbon Alloy Iron: Resists thermal cracking and warping with friction surfaces slotted on both sides for even wear
- Floating Hardware: Stainless steel bobbins allow thermal expansion between hat and ring preventing stress buildup
Product Notes
- Pair of left and right specific rotors included for complete front brake upgrade
- Bed-in rotors with 10 hard stops from 60-10 mph before track use
- Ships as one oversized package with protective foam wrapping
Installation Notes
- Professional installation recommended.
- Bolt-on replacement using OEM caliper hardware and pads
- Compatible with factory PCCB calipers on 997 Turbo and steel calipers on GT4

Brake Rotors
Brake rotors work with brake pads to bring your vehicle to a controlled stop. Upgrading from worn or stock rotors to a performance or OE-quality replacement improves braking consistency, reduces fade, and restores the original factory feel. Popular ProductsPopular brake rotor choices include EBC Brakes USR slotted rotors, Brembo OE-replacement rotors, StopTech Sport cross-drilled and slotted rotors, and Centric Premium rotors for OE-quality service replacement. What is the difference between slotted, drilled, and blank rotors?Blank rotors are standard OE-style with no machining, suitable for daily drivers. Slotted rotors have channels cut into the face for debris evacuation and improved high-heat performance. Cross-drilled and slotted rotors combine both features but may crack under extreme track use. How do I know when brake rotors need replacement?Replace rotors when rotor thickness falls below the minimum spec stamped on the rotor hat, when lateral runout exceeds 0.003 inches, or...

GiroDisc
GiroDisc manufactures premium two-piece floating brake rotors designed for performance street and track applications where reduced unsprung weight, superior thermal management, and consistent pedal feel under repeated hard braking are required. The two-piece design separates the cast iron friction ring from the aluminum hat using a patented floater system that allows the rotor to expand thermally without transmitting warping stress to the hub, eliminating the judder and pedal pulsation that single-piece rotors develop after repeated track sessions. GiroDisc rotors are available for a wide range of European and Japanese sports cars including Porsche, BMW M, Ferrari, Lamborghini, and the Subaru WRX, targeting enthusiasts and racers who demand the same engineering quality in their brake hardware as in their suspension and engine components. The significant weight reduction compared to equivalent cast iron rotors improves both acceleration and braking response by reducing the rotational...
