Brembo F85 X5M / F86 X6M GT-S Big Brake Kit - 405x34mm 2-Piece Front
The Brembo GT-S Big Brake Kit for the BMW F85 X5M and F86 X6M represents a significant upgrade in braking performance, engineered for drivers who demand consistent stopping power under both street and track conditions. Designed with motorsport-derived technology, this system improves thermal capacity, pedal feel, and overall braking confidence during aggressive driving.
At the core of the GT-S system are Brembo’s 6-piston cast monobloc radial mount calipers paired with large 405x34mm 2-piece floating discs. This combination delivers increased clamping force, improved heat dissipation, and more precise modulation compared to the factory braking system. Whether on the road or under heavy braking conditions, the result is stronger, more consistent braking with reduced fade under repeated high-load use.
The high carbon alloy discs feature a corrosion-resistant finish and Brembo’s advanced floating mounting system with an anti-rattle spring. Combined with a curved vane internal ventilation design, the system is optimized to manage heat efficiently, maintaining braking performance and pedal consistency even in demanding environments.
