The Brembo 1B3.8030A1 Gran Turismo (GT) Big Brake Kit delivers race-proven braking technology for high-performance street and track applications. This comprehensive brake upgrade system utilizes larger calipers and rotors to dramatically increase brake torque and thermal capacity, providing superior stopping power and fade resistance under extreme conditions.

Two-Piece Rotor Applications Include:

• Brembo multi-piston calipers (2, 4, 6, or 8 piston depending on application) with sequentially sized pistons for balanced brake force distribution
• Two-piece floating hat and rotor assemblies that reduce unsprung and rotating weight while improving heat dissipation
• Drilled or slotted two-piece rotors available up to 16 inches (405mm) in diameter
• DOT/TÜV approved stainless steel braided brake lines for improved pedal feel and durability
• High-performance Brembo brake pads engineered for aggressive stopping power
• Floating anti-rattle hardware to eliminate brake noise
• Precision-machined billet aluminum caliper mounting brackets
• Available caliper colors: red, black, or silver

One-Piece Rotor Applications Include:

• Brembo 2 or 4 piston calipers (depending on application) with sequentially sized pistons
• Drilled or slotted one-piece rotors up to 14 inches (355mm) in diameter
• DOT/TÜV approved stainless steel braided brake lines
• High-performance Brembo brake pads
• Billet aluminum caliper mounting brackets
• Available caliper colors: red, black, or silver

Most Gran Turismo applications include TÜV certification and are fully compatible with ABS and traction control systems. All necessary hardware is included for seamless installation. Note: Wheel measurement and clearance verification are critical for proper fitment before installation.
