GiroDisc 380x34mm Replacement Rings for Brembo Wide Annulus (62mm) Fits Porsche 911 GT3 996/997/991

GiroDisc 380x34mm Replacement Rings serve as direct friction ring replacements for GiroDisc two-piece front brake rotors with Brembo wide annulus design.

• Exact Dimensions: 380mm diameter x 34mm thickness matches OEM specs for plug-and-play installation
• Brembo 62mm Annulus Compatible: Locks securely into GiroDisc hats for floating two-piece operation
