The Brembo GT Big Brake Kit (1N3.9537A1) delivers race-proven stopping power and heat management for high-performance BMW applications. This comprehensive upgrade system features massive 405x34mm two-piece slotted Type-3 rotors paired with Brembo's iconic black-finished aluminum calipers.

Key Features:

• 405x34mm (15.9x1.3 inch) two-piece floating rotors with Type-3 slotting pattern for improved heat dissipation and pad bite
• Forged aluminum monobloc calipers with black anodized finish and Brembo logo
• Six-piston (M6) front caliper design for even pad pressure distribution and consistent pedal feel
• Two-piece rotor construction reduces unsprung weight while maintaining thermal stability
• High-performance brake pads designed specifically for the caliper and rotor combination
• Direct bolt-on installation using factory mounting points
• Complete hardware and braided stainless steel brake lines included

Engineered for BMW X5M (E70 2009-2013), X6M (E71 2009-2014), and X5M (F85 2015+) models, this front axle kit provides the thermal capacity and braking force needed for track days, spirited driving, and towing applications. The slotted rotor design continuously refreshes the pad surface while evacuating gases and debris for fade-resistant performance. Brembo's GT systems are DOT-compliant and designed to work with factory ABS and stability control systems.
