Brembo 2C1.8001A3 GT Piston Big Brake Kit Drilled Rotors - 4 Rear 345mm Silver

The Brembo Gran Turismo (GT) 4 Piston Rear Brake System is a complete bolt-on brake upgrade kit designed specifically for the 2001-2006 BMW E46 M3. This rear axle system features 345x28mm 2-piece drilled rotors with silver calipers, providing exceptional stopping power for both daily driving and high-performance track use.

Complete Brake System Kit Includes:

• 4-piston fixed aluminum brake calipers in silver finish
• 345mm x 28mm 2-piece vented and drilled brake rotors
• High-performance brake pads
• Stainless steel braided brake lines
• Aircraft-quality mounting brackets and hardware

Key Features:

• Direct bolt-on installation using OEM suspension mounting points
• Fully compatible with stock brake master cylinder and ABS system
• Bi-angle chamfered cross-drilled holes reduce stress cracking under high temperatures
• Corrosion-resistant coating on rotors eliminates rust and provides aggressive appearance
• 2-piece rotor design reduces unsprung weight and improves heat dissipation
• Fixed caliper design ensures even pad wear and consistent brake feel

The Brembo GT system delivers superior braking performance compared to stock brakes, with larger rotor diameter and increased pad area for improved heat management during demanding driving conditions. The drilled rotor surface helps dissipate gases and maintain consistent friction during repeated hard braking.

Important: Wheel clearance measurement is critical for proper fitment. Verify your wheels provide adequate clearance for the larger caliper and rotor assembly before installation. Minor modification to OEM components may be required.
