Brembo 1N2.9001A3 Gran Turismo Big Brake Kit with Multi-Piston Calipers

The Brembo Gran Turismo (GT) Big Brake Kit delivers professional-grade braking performance through advanced caliper and rotor technology. By utilizing larger calipers with increased piston count and oversized discs, this system dramatically increases thermal capacity and brake torque for demanding street and track applications.

Two-Piece Rotor Configuration Features:

• Multi-piston calipers (2, 4, 6, or 8 pistons depending on application) with sequentially sized pistons for balanced pad wear
• Two-piece floating hat and rotor assemblies that reduce unsprung weight and improve heat dissipation
• Drilled or slotted rotors available up to 16 inches (405mm) in diameter
• Available in red, black, or silver caliper finishes

One-Piece Rotor Configuration Features:

• 2 or 4 piston calipers (application-dependent) with sequentially sized pistons
• Drilled or slotted one-piece rotors up to 14 inches (355mm) in diameter
• Cost-effective alternative while maintaining performance upgrade benefits

Complete Kit Includes:

• DOT/TÜV approved stainless steel braided brake lines
• High-performance Brembo brake pads
• Billet aluminum caliper mounting brackets
• Floating anti-rattle hardware (two-piece rotor kits)
• All necessary installation hardware

This system is fully compatible with ABS and traction control systems. Most GT applications include TÜV certification. Proper wheel clearance measurement is critical for fitment—verify wheel dimensions before ordering to ensure adequate clearance for the larger caliper and rotor assembly.
