Brembo 1B1.8015A3 GT 4-Piston Big Brake Kit Front 355mm Drilled Silver

The Brembo Gran Turismo (GT) 4-Piston Big Brake Kit delivers exceptional stopping power for both spirited street driving and track use. This complete front brake upgrade system is engineered specifically for the 2001-2006 BMW E46 M3, featuring a direct bolt-on installation that maintains full compatibility with the factory brake master cylinder and ABS system.

System Specifications:

• 355mm x 32mm 2-piece drilled and vented front rotors with bi-angle chamfered holes to minimize stress cracking
• Fixed 4-piston aluminum calipers in silver finish for superior heat dissipation and consistent pedal feel
• High-performance brake pad compound optimized for street and track applications
• Stainless steel braided brake lines for improved pedal response and fade resistance
• Aircraft-quality mounting brackets and complete hardware kit
• Corrosion-resistant rotor coating for durability and aggressive appearance

Installation Notes:

• Designed for front axle installation only
• Requires minor modification to OE components
• Wheel clearance verification is critical—minimum wheel dimensions must be confirmed before installation
• Professional installation recommended for proper bleeding and bedding procedures

Brembo Gran Turismo systems represent the perfect balance of daily drivability and high-performance capability, providing massive improvements in brake torque, fade resistance, and thermal management compared to stock braking systems. The 2-piece rotor design reduces unsprung weight while the larger diameter increases thermal capacity for sustained hard braking.
