The Brembo Gran Turismo (GT) Big Brake Kit represents the pinnacle of high-performance braking technology for street and track applications. This comprehensive upgrade system utilizes larger calipers and rotors to dramatically increase thermal capacity and brake torque, delivering exceptional stopping power and fade resistance under demanding 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 improving heat dissipation
• Drilled or slotted rotors available up to 16 inches (405mm) in diameter
• DOT/TUV-approved stainless steel braided brake lines for improved pedal feel and consistency
• 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: red, black, or silver

One-Piece Rotor Applications Include:

• Brembo 2 or 4-piston calipers 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: red, black, or silver

Most Gran Turismo applications include TUV 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 ordering.
