Brembo 01-06 M3 Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted TY3L - Black

The cast iron caliper body on this Brembo GT Big Brake Kit is a solid foundation for serious stopping power. This kit is specifically designed for the rear of the 2001-2006 BMW M3, giving you a substantial upgrade over the factory setup. Brembo is well-known for their high-performance braking systems, and this kit brings that expertise to your vehicle, aiming to improve both fade resistance and overall braking feel during spirited driving or track use.

This kit features a 4-piston caliper design, which helps distribute clamping force more evenly across the larger 345x28mm two-piece rotors. The rotors themselves are slotted, a design choice that helps to vent gases and heat away from the pad surface. This venting action is crucial for maintaining consistent braking performance, especially under heavy load, preventing the buildup of heat that can lead to brake fade. The two-piece rotor construction also offers benefits, allowing for better thermal management and potentially reducing unsprung weight compared to a single-piece rotor of the same size.

When installing a kit of this caliber, it's important to ensure all components are properly fitted and bled according to Brembo's specifications. This system is built to handle demanding use, and proper installation is key to unlocking its full potential. While this kit is designed as a direct upgrade, always refer to the manufacturer's installation guide for detailed instructions and any specific tool requirements.
