Brembo 2PD.9054AS GT-S Series 4-Piston Rear Big Brake Kit with Slotted 2-Piece Rotors

The Brembo 2PD.9054AS is a GT-S Series Rear Big Brake Kit engineered to deliver a dramatic upgrade over factory rear braking systems. Part of Brembo's performance aftermarket lineup, this kit pairs 4-piston cast monobloc radial-mounted aluminum calipers with slotted 2-piece floating rotors for exceptional stopping power, superior heat management, and confident pedal feel under both street and track conditions.

Key Features:

• 4-Piston Cast Monobloc Calipers — Radial-mounted, machined from a single casting for maximum rigidity and minimal flex under hard braking
• Slotted 2-Piece Floating Rotors — Advanced high carbon alloy construction with an exclusive venting system that improves cooling capacity and increases resistance to thermal-shock cracking by over 40%
• Floating D-Bobbin Rotor Mounting System — Allows the friction ring to float independently of the hat, reducing noise, vibration, and thermal distortion
• Brembo High-Performance Brake Pads Included — Matched friction compounds optimized for use with the GT-S caliper and rotor combination
• Stainless Steel Braided Brake Lines Included — DOT/TÜV approved for safe, consistent pedal feel
• CNC Billet Caliper Adapters & Hardware Included — Engineered mounting brackets and all necessary fasteners for a complete, bolt-on installation
• ABS and Traction Control Compatible — Designed to integrate seamlessly with OEM electronic braking systems
• Hard Anodized Caliper Finish — Provides long-term corrosion resistance and durability at elevated operating temperatures

The GT-S system is Brembo's street-and-track performance tier, developed from decades of motorsport engineering experience. 2-piece floating rotor construction dramatically reduces brake fade and improves thermal capacity compared to solid one-piece discs, making this kit ideal for high-performance driving enthusiasts. The kit ships pre-assembled and includes all components necessary for a complete rear axle brake upgrade. Brembo backs this kit with a 2-year warranty against manufacturing defects from the date of purchase.
