Brembo 1M1.9001A2 GT 4-Piston Rear Big Brake Kit 345x28mm 2-Piece

The Brembo Gran Turismo (GT) 4-Piston Big Brake Kit is engineered specifically for the 2001-2006 BMW M3 (E46) rear axle, featuring 345x28mm 2-piece vented rotors. This complete brake upgrade system delivers exceptional stopping power for both daily driving and high-performance street and track applications.

Complete Bolt-On System:

Each Gran Turismo brake kit includes everything needed for installation: high-performance fixed aluminum 4-piston calipers, large-diameter 2-piece vented brake rotors, performance brake pads, stainless steel braided brake lines, and aircraft-quality mounting brackets and hardware. The system is designed to bolt directly onto the vehicle's original suspension and remains fully compatible with the stock brake master cylinder and anti-lock braking system (ABS).

Key Features:

• Fixed aluminum 4-piston calipers available in red, silver, or black finishes
• 345mm diameter x 28mm thick 2-piece vented rotors for superior heat dissipation
• Cross-drilled or slotted rotor surfaces depending on application
• Bi-angle chamfered drill holes reduce stress cracking under high-temperature conditions
• Corrosion-resistant rotor coating eliminates rust and provides aggressive appearance
• Stainless steel braided brake lines for improved pedal feel and durability
• Direct bolt-on installation with no modifications required

Important: Wheel fitment verification is critical before ordering. Measure your wheels carefully to ensure proper clearance for the larger calipers and rotors. The Gran Turismo system significantly increases braking performance while maintaining compatibility with your vehicle's existing brake systems.

Brembo Gran Turismo systems are the ideal upgrade for enthusiasts seeking track-capable braking performance with street-friendly characteristics. The 2-piece rotor design reduces unsprung weight while providing excellent thermal management during demanding driving conditions.
