Brembo 3K3.9046AZ Big Brake Kit High-Performance Upgrade System

The Brembo 3K3.9046AZ is a complete Big Brake Kit (BBK) engineered by Brembo, the world's leading manufacturer of high-performance braking systems. Designed for drivers who demand superior stopping power beyond what factory brakes can deliver, this kit delivers the precision, feel, and fade resistance that Brembo is globally renowned for.

Brembo Big Brake Kits are engineered as a complete, bolt-on braking upgrade, combining oversized rotors and multi-piston calipers to dramatically increase braking surface area and clamping force. The result is shorter stopping distances, reduced brake fade under sustained high-heat conditions, and improved pedal feel and modulation.

Key Features:

• Brembo-engineered complete system — every component designed and tested to work together for optimal performance
• Multi-piston caliper design — provides even pad pressure across the full rotor surface for consistent, fade-resistant braking
• Oversized rotor diameter — dramatically increases thermal mass and heat dissipation compared to OEM brakes
• Premium brake pads included — matched to the caliper and rotor for immediate, optimized performance out of the box
• Brembo quality materials — aerospace-grade aluminum caliper bodies and high-carbon rotor metallurgy for long-lasting durability
• Direct bolt-on fitment — includes all necessary brackets, hardware, and brake lines for a complete installation
• Track and street capable — delivers performance under both spirited street driving and sustained high-load track use

As the OEM brake supplier to some of the world's most prestigious automotive manufacturers, Brembo brings factory-level engineering and quality to this aftermarket upgrade. The 3K3.9046AZ kit ensures your vehicle's braking system is fully capable of matching the demands of a performance-oriented driving style.
