Brembo 06-12 325i (Excl. xDrive) Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type3-Black HA

If you're looking to significantly improve the stopping power and heat management for your 2006-2012 BMW 325i (excluding xDrive models), this Brembo GTS Big Brake Kit for the rear is a serious upgrade. This kit is designed to handle the demands of spirited driving and track use, offering a substantial improvement over the stock braking system. It's a comprehensive package that addresses both the thermal and mechanical aspects of braking performance.

At the heart of this kit are the 4-piston calipers, precision-cast for strength and rigidity. These calipers work with 345x28mm two-piece rotors that feature a slotted design. The slots on the rotor surface help to sweep away dust and gas that can build up between the pad and rotor, ensuring consistent contact and preventing fade, especially during prolonged braking events. The two-piece rotor construction allows for better thermal management, as the aluminum hat can dissipate heat more effectively than a solid one-piece rotor. The black HA finish on the calipers adds a clean, performance-oriented look to your vehicle.

This Brembo kit is a well-built system that aims to provide a noticeable difference in braking feel and performance. When installing a big brake kit like this, it's always a good idea to consult the manufacturer's installation guide to ensure all components are fitted correctly. While this kit focuses on the rear, it's designed to work harmoniously with your vehicle's existing front braking system, offering a balanced upgrade.
