Brembo 01-06 M3 Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Black HA

The 345x28mm, two-piece rotors in this Brembo Big Brake Kit are cast iron with a directional vane design, helping to dissipate heat more effectively than solid rotors. This kit is specifically for the rear of the 2001-2006 BMW M3, giving you a significant upgrade over the factory braking system.

This kit includes Brembo's 4-piston calipers, known for their solid construction and consistent clamping force. The calipers are finished in black, and the rotors are drilled, which helps to shed heat and gasses during hard braking. The two-piece rotor design allows for better thermal management, as the rotor ring can expand and contract independently of the caliper mounting hat. This setup is designed to handle the demands of spirited driving and track use, offering improved stopping power and fade resistance.

When installing this kit, you'll want to ensure you have the necessary tools and potentially a helper, as brake system work can be involved. It's always a good idea to consult the manufacturer's installation guide for specific torque values and procedures. This kit is a substantial upgrade for your M3's braking performance.
