Brembo 2S1.9005A5 GT Big Brake Kit Drilled Rotors Yellow Calipers - Rear 380x28mm 2-Piece

The Brembo 2S1.9005A5 GT Series Big Brake Kit delivers professional-grade braking performance engineered specifically for Porsche Cayenne models. This complete rear axle upgrade kit features Brembo's advanced BM4 billet monoblock 4-piston calipers paired with oversized 380x28mm 2-piece drilled rotors for exceptional stopping power, heat management, and fade resistance during spirited driving or track use.

BM4 Billet Monoblock Caliper Technology:

• 4-piston radial-mounted fixed caliper machined from a single billet of cast aluminum for maximum rigidity and minimal deformation
• Innovative 4D casting technology with internal fluid passages eliminates external brake lines for cleaner aesthetics and superior functionality
• Single integrated bleed point simplifies maintenance while maintaining professional performance standards
• Vibrant yellow powder-coated finish with precision-machined Brembo logo for distinctive motorsport appearance
• Opposed piston design ensures even brake force distribution and uniform pad wear

2-Piece Drilled Rotor Design:

• 380mm diameter x 28mm thickness provides significantly increased thermal capacity over factory brakes
• Lightweight 2-piece floating design with aluminum bell reduces unsprung weight for improved handling response
• Cross-drilled pattern effectively dissipates brake gases, removes water and debris, and prevents pad glazing
• Advanced high-carbon alloy construction with corrosion-resistant coating for extended durability
• Exclusive curved-vane ventilation system improves cooling capacity and increases resistance to thermal cracking by over 40%
• Proprietary floating bobbin hardware with anti-rattle springs eliminates noise typically associated with floating disc designs

Complete Kit Includes:

• Pair of BM4 4-piston billet monoblock calipers with yellow finish
• 380x28mm 2-piece drilled brake rotors (2)
• High-performance brake pads optimized for maximum grip in all conditions
• Stainless steel braided brake lines for consistent pedal feel and improved durability
• All necessary mounting hardware, brackets, and adapters for direct bolt-on installation

This GT Series brake system is designed for enthusiasts seeking improved braking performance, superior heat management, and enhanced pedal feel for both daily driving and occasional track use. The kit ships pre-assembled and is fully compatible with the vehicle's factory ABS and traction control systems. Installation requires no modifications to the master cylinder or brake system architecture.

Performance Benefits: Experience noticeably more immediate and decisive braking with consistent performance even during demanding track sessions. The larger rotors and advanced caliper design deliver increased brake torque, reduced stopping distances, and fade-resistant performance that remains stable under extreme temperatures. Enhanced pedal modulation provides precise control and confidence-inspiring feedback in all driving conditions.
