Brembo 1B3.8030A3 Gran Turismo Big Brake Kit with Two-Piece Rotors

The Brembo 1B3.8030A3 Gran Turismo (GT) Big Brake Kit represents the pinnacle of high-performance braking technology for street and track applications. This complete brake upgrade system utilizes oversized calipers and rotors to dramatically increase brake torque and thermal capacity, delivering superior stopping power and fade resistance under demanding driving conditions.

Two-Piece Rotor Design:

This kit features Brembo's advanced two-piece floating hat and rotor assemblies that reduce unsprung and rotating weight while improving heat dissipation. The floating design allows the rotor to expand independently from the aluminum hat during heat cycles, reducing thermal stress and extending component life.

Complete Kit Includes:

• Brembo multi-piston calipers (2, 4, 6, or 8 piston depending on application) with sequentially sized pistons for balanced pad wear and optimal pressure distribution
• Two-piece drilled or slotted rotors up to 16 inches (405mm) in diameter
• High-performance brake pads formulated for aggressive stopping with minimal fade
• DOT/TÜV approved stainless steel braided brake lines for improved pedal feel
• Billet aluminum caliper mounting brackets for precise positioning and strength
• Floating anti-rattle hardware for quiet operation
• Complete installation hardware for seamless fitment

Performance Features:

• Fully compatible with ABS and traction control systems
• Available in red, black, or silver caliper finish options
• Most GT applications include TÜV certification
• Engineered for direct bolt-on installation with no modifications required

Important: Proper wheel clearance measurement is critical for fitment. Verify that your wheels have adequate spoke and barrel clearance for the larger calipers and rotors before ordering. This is a complete front or rear axle kit designed for serious performance upgrades on European, domestic, and import performance vehicles.
