Brembo 1N1.8509A3 Gran Turismo Big Brake Kit with Performance Calipers

The Brembo Gran Turismo (GT) Big Brake Kit represents the pinnacle of high-performance braking technology for street and track applications. This complete brake upgrade system combines larger calipers and rotors to dramatically increase brake torque and thermal capacity, delivering superior stopping power and fade resistance under demanding conditions.

Two-Piece Rotor Applications Include:

• Brembo multi-piston calipers (2, 4, 6, or 8 piston depending on application) featuring 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/TUV-approved stainless steel braided brake lines for improved pedal feel and durability
• High-performance brake pads engineered specifically for GT applications
• Floating anti-rattle hardware for quiet operation
• Precision-machined billet aluminum caliper mounting brackets
• Caliper finish options in 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/TUV-approved stainless steel braided brake lines
• High-performance brake pads
• Billet aluminum caliper mounting brackets
• Caliper finish options in red, black, or silver

All Brembo GT systems are fully compatible with ABS and traction control systems. Most applications include TUV certification, and complete hardware is provided for straightforward installation. Proper wheel fitment verification is required before installation to ensure adequate clearance for the larger caliper and rotor assembly.
