GiroDisc 380x32mm 10 Pin Holes 52mm Annulus Slotted Rings for 2007-2009 Porsche 911 GT3 GT3 RS GT2
GiroDisc 380x32mm slotted rings serve as direct-replacement friction rings for 2-piece front brake rotors on 2007-2009 Porsche 911 GT3 GT3 RS and 2007 GT2 models. These rings pair with GiroDisc hats to create a lightweight floating assembly that handles high-heat track sessions. Slotted surfaces clear pads and dissipate heat for reliable stops lap after lap.
Key Features
- Slotted Design: Narrow slots on both sides channel gases and water away from pads while drawing in cool air to fight fade during extended hard braking.
- 380x32mm Sizing: Matches OEM dimensions for bolt-on fit with stock calipers and pads on Porsche 911 GT3 applications.
- 10 Pin Holes 52mm Annulus: Precision-drilled for secure attachment to aluminum hats using stainless bobbins ensuring true floating action.
- High-Carbon Cast Iron: Stress-relieved alloy withstands track abuse with strong bite and resistance to thermal cracking.
