Brembo 4KC.8012AX GT Big Brake Kit 4-Piston Caliper Upgrade

The Brembo 4KC.8012AX is a complete Gran Turismo (GT) Big Brake Kit engineered for drivers who demand maximum stopping power and fade resistance. Built on Brembo's legendary motorsport heritage, this kit replaces the factory brake system with a high-performance, purpose-built assembly designed for track use, high-performance street driving, and demanding towing or hauling applications.

Key Features:

• Brembo GT Series Monoblock Caliper: Precision-machined from high-strength aluminum alloy for reduced unsprung weight and superior rigidity
• Multi-Piston Caliper Design: Delivers even pad-to-rotor contact pressure for consistent, progressive braking feel
• Slotted and/or Drilled High-Carbon Rotors: Improves heat dissipation and outgassing under extreme braking conditions
• Direct-Fit Caliper Bracket: Bolt-on installation using factory mounting points — no cutting or welding required
• High-Performance Brake Pads Included: Track-compound pads optimized for high-temperature stability and reduced brake fade
• Stainless Steel Braided Brake Lines: Minimize line expansion for a firm, consistent pedal feel
• Anodized Caliper Finish: Corrosion-resistant coating provides long-lasting appearance behind the wheel

Brembo's GT Big Brake Kits are developed using the same engineering principles behind their Formula 1, MotoGP, and endurance racing systems. The 4KC.8012AX is a direct upgrade over the OEM brake package, delivering dramatically shorter stopping distances, improved pedal modulation, and reduced brake fade during repeated hard stops. Each kit is assembled and quality-inspected to Brembo's exacting standards.
