Brembo 1B3.8003A2 Gran Turismo Big Brake Kit

The Brembo 1B3.8003A2 Gran Turismo (GT) Big Brake Kit delivers race-proven braking technology for high-performance street and track applications. Engineered with larger calipers and rotors, this system dramatically increases brake torque and thermal capacity compared to stock brakes, providing consistent stopping power under extreme conditions.

Two-Piece Rotor Applications Include:

• Brembo multi-piston calipers (2, 4, 6, or 8 pistons depending on application) with sequentially sized pistons for balanced pad wear and optimal pressure distribution
• Two-piece floating hat and rotor assemblies that reduce unsprung and rotating weight while enhancing 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 noise and vibration
• 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 complete installation. Note: Wheel measurement is critical for proper fitment—verify brake-to-wheel clearance before installation.
