Brembo 1B3.8013A2 Gran Turismo Big Brake Kit with Multi-Piston Calipers

The Brembo 1B3.8013A2 Gran Turismo Big Brake Kit delivers race-proven braking technology for high-performance street and track applications. Engineered with larger calipers and rotors, this system significantly increases thermal capacity and brake torque compared to stock brake systems, providing superior stopping power and fade resistance under demanding conditions.

Two-Piece Rotor Configuration:

• 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 reduce unsprung and rotating weight while improving heat dissipation
• Drilled or slotted rotors available up to 16 inches (405mm) in diameter
• DOT/TÜV approved stainless steel braided brake lines for consistent pedal feel
• High-performance brake pads engineered specifically for Brembo calipers
• Floating anti-rattle hardware minimizes noise and vibration
• Precision-machined billet aluminum caliper mounting brackets
• Available in red, black, or silver caliper finishes

One-Piece Rotor Configuration:

• Cost-effective upgrade featuring 2 or 4 piston calipers 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 brake pads and billet caliper mounting brackets included
• Available in red, black, or silver caliper finishes

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. Proper wheel clearance measurement is critical for fitment—verify your wheel specifications before installation to ensure compatibility with the larger caliper and rotor assembly.
