Brembo 2P3.8040AS GT-S M4 Type 3 Rear Brake Kit - 345x28mm 2-Piece Slotted Rotors

The Brembo GT-S brake system represents a significant upgrade for enthusiasts seeking track-capable stopping power with street-friendly refinement. This rear axle kit features 345x28mm two-piece slotted rotors paired with Brembo's M4 Type 3 calipers finished in black hard anodized coating for exceptional durability and heat dissipation.

Key Features:

• 345x28mm (13.6x1.1 inch) two-piece floating rotor design reduces unsprung weight while improving thermal management
• Type 3 slotted rotor pattern enhances pad bite and evacuates gases for consistent performance
• M4 four-piston monobloc calipers machined from billet aluminum for rigidity and precision
• Black hard anodized caliper finish provides superior corrosion resistance and a stealthy appearance
• Aluminum top-hat design with directional curved vanes for optimized cooling
• Complete bolt-on kit includes rotors, calipers, high-performance brake pads, and all necessary hardware
• DOT-compliant brake lines and mounting brackets included for direct fitment

Brembo's GT-S systems bridge the gap between street and track, offering fade-resistant performance during spirited driving while maintaining excellent modulation and low dust characteristics for daily use. The two-piece rotor construction allows for replacement of wear surfaces without replacing the aluminum hat, reducing long-term maintenance costs. Originally developed for BMW F10/F11 5-Series applications including 528i and 528i xDrive models (2011-2016).
