Brembo 4K3.9006AX GT Big Brake Kit High-Performance Upgrade

The Brembo 4K3.9006AX is a GT Series Big Brake Kit engineered for drivers who demand maximum stopping power on both the street and the track. Built on decades of motorsport expertise, this complete brake upgrade kit delivers superior fade resistance, consistent pedal feel, and dramatically increased thermal capacity over stock braking systems.

Key Features:

• Monoblock Aluminum Calipers: Machined from a single billet of cast aluminum for outstanding rigidity and minimized deformation under extreme braking loads
• Multi-Piston Caliper Design: Provides even, consistent clamping force across the rotor surface for improved modulation and stopping power
• 2-Piece Floating Rotor Assembly: Features Brembo's exclusive venting system that improves cooling capacity and increases resistance to thermal shock cracking
• High-Performance Brake Pads: Included as standard with friction materials optimized for both street and track driving conditions
• Stainless Steel Braided Brake Lines: TUV/DOT homologated lines included for improved pedal feel and fluid pressure consistency
• CNC Billet Caliper Adapters: Precision-machined hardware ensures a proper, secure fit
• Complete Hardware Kit: All necessary brackets, adapters, fasteners, and installation hardware included

Performance Benefits:

• Significantly reduced braking distances compared to OEM systems
• Superior heat dissipation reduces brake fade under repeated hard stops
• Reduced unsprung weight improves suspension dynamics and overall handling
• Corrosion-resistant caliper finish for long-term durability and appearance

The Brembo GT Big Brake Kit is designed and tested specifically for performance driving enthusiasts who require superlative braking performance in both everyday and demanding track-day conditions. Brembo backs this kit with a two-year warranty against manufacturing defects.
