Brembo 1N3.9001AS GT-S Front Big Brake Kit 380x34mm 6-Piston Black Anodized

The Brembo GT-S Series Front Big Brake Kit delivers race-inspired performance for BMW M5 (E60) and M6 (E63/E64) models. This complete front axle upgrade features massive 380mm x 34mm two-piece slotted rotors paired with cast monobloc 6-piston calipers finished in hard anodized black.

Key Features:

• Cast Monobloc 6-Piston Calipers: Machined from a single piece of aluminum for exceptional rigidity and lighter weight compared to traditional multi-piece designs, with hard anodized finish for superior heat and corrosion resistance
• 380mm x 34mm Two-Piece Rotors: Large diameter slotted discs with Type 3 (TY3) slot pattern continuously refresh the pad surface, removing debris and maintaining consistent friction coefficient
• Racing-Inspired Design: Features ventilated pistons, recessed dust seals, and construction capable of withstanding extreme thermal and mechanical stress on the track
• Radial Mount Design: Provides even brake force distribution, greater caliper stiffness, and uniform pad wear for consistent performance
• Complete Kit: Ships pre-assembled with high-performance brake pads, stainless steel braided brake lines, mounting hardware, and caliper adapters for straightforward installation

The GT-S Series represents the perfect bridge between street and track use, offering increased thermal capacity to eliminate brake fade during aggressive driving while maintaining excellent modulation and pedal feel for daily use. This system significantly outperforms factory brakes with larger, directionally-vented rotors that optimize cooling and resist thermal shock for enhanced safety and extended durability.
