Brembo 1B3.8050A2 Gran Turismo Big Brake Kit with Two-Piece Rotors

The Brembo 1B3.8050A2 Gran Turismo (GT) Big Brake Kit delivers professional-grade braking performance through advanced engineering and premium materials. This complete brake system upgrade features larger calipers and oversized rotors that significantly increase thermal capacity and brake torque, making it ideal for both high-performance street driving and track applications.

Two-Piece Rotor Design Benefits:

This kit utilizes Brembo's innovative two-piece floating hat and rotor assembly, which reduces unsprung and rotating weight while improving heat dissipation. The separated design allows for better thermal management and can accommodate rotors up to 16 inches (405mm) in diameter with drilled or slotted configurations for enhanced cooling and wet-weather performance.

Complete Kit Includes:

• Brembo multi-piston calipers with sequentially sized pistons for balanced brake force distribution (available in red, black, or silver finish)
• Two-piece floating rotor assemblies with drilled or slotted face options
• High-performance brake pads engineered for aggressive stopping power
• DOT/TÜV approved stainless steel braided brake lines for consistent pedal feel
• Billet aluminum caliper mounting brackets for rigid, precise caliper positioning
• Floating anti-rattle hardware to eliminate brake noise
• Complete installation hardware for seamless integration

Important Notes:

This brake system is fully compatible with factory ABS and traction control systems. Many GT applications include TÜV certification for European compliance. Proper wheel clearance measurement is critical before ordering—verify that your wheels provide adequate clearance for the larger caliper and rotor assembly to ensure proper fitment.
