Brembo 2P1.8030AS GT-S Rear Big Brake Kit 345x28mm Drilled 2-Piece Hard Anodized

The Brembo 2P1.8030AS GT-S Series Rear Big Brake Kit delivers motorsports-derived performance for 2005-2011 Porsche 987 Boxster and 2006-2012 Porsche 987 Cayman models. This complete rear axle braking system features cast monobloc radial-mounted calipers and oversized 2-piece drilled rotors engineered to provide superior stopping power and fade resistance for both street driving and demanding track sessions.

Key Features:

• 4-piston cast monobloc radial-mounted calipers with hard anodized finish
• 345mm x 28mm (13.6") 2-piece cross-drilled rotors with aluminum hat design
• Directionally vented discs for enhanced cooling and heat dissipation
• Cross-drilled rotor surface continuously cleans and refreshes pad surface
• Aluminum hat construction reduces unsprung weight for improved handling
• High-performance brake pads with aggressive friction material included
• TÜV/DOT approved Goodridge stainless steel braided brake lines
• Complete axle set with all necessary mounting hardware
• Ships pre-assembled for simplified installation

The GT-S Series represents Brembo's most popular high-performance street-to-track brake system, offering significant advantages over OEM brakes through increased thermal capacity, superior brake modulation, and consistent pedal feel even under repeated heavy braking. The 2-piece floating disc design with aluminum hat reduces rotational mass while managing thermal stress more effectively than stock brakes, delivering improved braking performance and enhanced driving dynamics.
