Brembo UPGRADE GT 2-Piece Slotted TY3 Front Discs for 981 / 982 Porsche Boxster and Cayman | 99x 911 Carrera and Turbo

The Brembo UPGRADE GT 2-Piece Slotted TY3 Front Discs for the 981 and 982 Porsche Boxster / Cayman and 99x 911 Carrera / Turbo models offer a high-performance replacement for the factory rotors with a track-bred two-piece design. Each 350mm x 34mm rotor features a high-carbon iron outer disc paired with a precision-machined aluminum hat, joined using a floating D-bobbin system with integrated anti-rattle springs to optimize heat dissipation, reduce unsprung weight, and maintain thermal stability under repeated hard braking. The TY3 slotted configuration — developed directly from Brembo’s motorsport experience — delivers aggressive initial bite, consistent pad contact, and improved debris evacuation. Corrosion-resistant plating adds long-term durability, while the discs’ direct-fit compatibility with OEM calipers ensures they maintain excellent street drivability alongside enhanced braking response and pad wear control for spirited and track use.
