Brembo 1B3.8046A1 Gran Turismo Big Brake Kit

The Brembo 1B3.8046A1 Gran Turismo (GT) Big Brake Kit represents the pinnacle of high-performance braking technology for street and track applications. By utilizing larger diameter rotors and multi-piston calipers, this system significantly increases brake torque and thermal capacity compared to stock braking systems, delivering exceptional stopping power and fade resistance under demanding conditions.

Two-Piece Rotor Applications Include:

• Brembo forged aluminum calipers with 2, 4, 6, or 8 pistons (application-dependent) featuring sequentially sized pistons for balanced pad wear
• Two-piece floating rotor design with aluminum hat and cast iron rotor ring reduces unsprung weight and enhances heat dissipation
• Drilled or slotted rotors available up to 16 inches (405mm) in diameter
• DOT and TÜV-approved stainless steel braided brake lines for improved pedal feel
• High-performance brake pads engineered specifically for the system
• Floating anti-rattle hardware for quiet operation
• Precision-machined billet aluminum caliper mounting brackets
• Choice of red, black, or silver caliper finishes

One-Piece Rotor Applications Include:

• Brembo 2 or 4-piston forged aluminum calipers with sequentially sized pistons
• Drilled or slotted one-piece cast iron rotors up to 14 inches (355mm) in diameter
• DOT and TÜV-approved stainless steel braided brake lines
• High-performance brake pads matched to the system
• Billet aluminum caliper mounting brackets
• Choice of red, black, or silver caliper finishes

Most Gran Turismo applications include TÜV certification for quality assurance. All Brembo GT brake systems are fully compatible with factory ABS and traction control systems. Each kit includes all necessary hardware for complete installation. Note: Wheel clearance verification is critical before ordering—measure your wheels carefully to ensure proper fitment of the larger brake components.
