Brembo 1N3.9506AS GT-S Front Brake Kit 405x34mm 2-Piece Slotted Rotors 6-Piston

The Brembo GT-S brake system represents a significant performance upgrade for BMW X5 (E70) and X6 (E71) models, delivering track-proven stopping power with street-friendly characteristics. This front axle kit features massive 405x34mm two-piece slotted Type-3 rotors paired with Brembo's forged aluminum monobloc six-piston calipers finished in hard anodized black.

Key Features:

• 405x34mm two-piece floating rotor design reduces unsprung weight while improving heat dissipation
• Type-3 directional slot pattern enhances pad bite, evacuates gases, and resists thermal cracking
• Forged aluminum monobloc six-piston calipers provide exceptional rigidity and consistent pedal feel
• Hard anodized black caliper finish offers superior corrosion resistance and a sleek appearance
• High-performance friction pads engineered specifically for the GT-S system
• Direct bolt-on installation with all necessary hardware and stainless steel braided brake lines included
• Compatible with OEM wheel sizes—no spacers required on most applications

Brembo's GT-S systems are engineered in Italy using the same technology developed for motorsports applications, providing substantially shorter stopping distances, improved fade resistance, and enhanced modulation compared to factory brakes. The two-piece rotor design separates the aluminum hat from the cast iron friction ring, allowing for thermal expansion while reducing rotating mass for improved handling response.

This system is specifically designed for 2007-2013 BMW X5 (E70) and 2008-2014 BMW X6 (E71) models. Complete front axle kit includes calipers, rotors, pads, mounting hardware, and brake lines for professional installation.
