Brembo 1S4.6002A6 GT BM4 Front Brake Kit 4-Piston 326x30mm Cross Drilled White Calipers

The Brembo GT | BM4 brake system delivers motorsport-derived technology and unrivalled performance for street and track applications. This complete front axle kit features 4-piston cast monobloc calipers paired with 326x30mm (12.8") cross-drilled 1-piece rotors, finished in striking white with the iconic Brembo logo.

Advanced Caliper Technology:

• Manufactured using an innovative 4D technology casting process, offering a design completely different from conventional calipers
• Internal fluid channels eliminate external rigid pipe connections for cleaner aesthetics and superior functionality
• Aluminum radial-mounted fixed calipers with opposing pistons for enhanced rigidity and uniform pad wear
• Multiple pistons with different diameters provide better-distributed pad action and more uniform wear

High-Performance Rotors:

• 326x30mm (12.8") cross-drilled (TY1) 1-piece disc design with 12mm air gap
• High carbon construction with corrosion-resistant plating for long-lasting performance
• Cross-drilled pattern creates escape paths for debris, dust, gases, and water
• Optimized ventilation system enhances cooling capacity and thermal shock resistance

Complete Kit Includes:

• Left and right 4-piston BM4 calipers with Brembo performance brake pads
• 326x30mm cross-drilled front rotors (pair)
• Stainless steel braided brake lines
• Mounting brackets and all necessary hardware for complete installation

The radial-mounted fixed calipers and oversized discs deliver more braking torque and greater thermal capacity, resulting in immediate and decisive braking for both street driving and consecutive track days. Engineered with optimal thermal resistance to reduce brake fade under high-performance or racing conditions, this system is trusted by enthusiasts and professional racers worldwide.
