Brembo 1B3.8034A1 Gran Turismo Big Brake Kit with Two-Piece Rotors

The Brembo 1B3.8034A1 Gran Turismo (GT) Big Brake Kit represents the pinnacle of high-performance braking technology for street and track applications. This comprehensive brake system upgrade features larger calipers and rotors that dramatically increase thermal capacity and brake torque, delivering unmatched stopping power and fade resistance under extreme conditions.

Two-Piece Floating Rotor Design:

This kit utilizes Brembo's advanced two-piece floating hat and rotor assembly, which reduces unsprung and rotating weight while improving heat dissipation. The floating design allows the rotor to expand and contract independently from the aluminum hat, minimizing thermal stress and warping during aggressive use.

Complete Kit Includes:

• Brembo multi-piston calipers with sequentially sized pistons for optimal pressure distribution (available in red, black, or silver finish)
• Two-piece drilled or slotted rotors up to 16 inches (405mm) in diameter
• High-performance Brembo brake pads engineered for GT applications
• DOT and TÜV approved stainless steel braided brake lines
• Billet aluminum caliper mounting brackets for precise fitment
• Floating anti-rattle hardware for quiet operation
• Complete hardware package for seamless installation

Key Performance Benefits:

• Significantly increased brake torque and stopping power
• Superior heat dissipation prevents brake fade during repeated hard stops
• Reduced unsprung weight improves suspension response and handling
• Fully compatible with factory ABS and traction control systems
• TÜV certification on most applications ensures proven quality and safety

Important: Proper wheel clearance measurement is critical for fitment. Verify that your wheels provide adequate clearance for the larger caliper and rotor assembly before ordering. This kit requires no modifications to existing brake system electronics and integrates seamlessly with OEM safety systems.
