Brembo 04-10 5-Series (Excl. xDrive/M5) Rr GT BBK 4Pist Cast 345x28 2pc Rotor Slotted TY3L - Yellow

When you open the box for this Brembo GT Big Brake Kit, you're getting a complete rear braking upgrade. Inside, you'll find a pair of yellow 4-piston aluminum calipers, two 345x28mm two-piece slotted rotors, and all the necessary hardware to get them installed. This kit is designed for 2004 through 2010 5-Series BMWs, specifically excluding the xDrive all-wheel-drive models and the high-performance M5 variants. It's a substantial upgrade over the factory braking components, aimed at drivers who demand more from their vehicle's stopping power.

The heart of this kit lies in its larger, two-piece rotors and the robust 4-piston calipers. The 345mm diameter and 28mm thickness of the rotors mean more surface area for heat dissipation and a stronger clamping force. Brembo's signature slotted rotor design helps to sweep away dust and gas that can build up between the pad and rotor surface, ensuring consistent braking performance even under heavy use. The calipers themselves are cast from aluminum, which helps to reduce unsprung weight while providing the rigidity needed to apply significant force to the pads. This combination works together to provide improved stopping distances and better fade resistance compared to stock brakes.

Installing a big brake kit like this is a significant undertaking, and it's important to ensure you have the right tools and knowledge. While this kit is designed to be a direct replacement for the factory rear brake components on compatible 5-Series models, it's always recommended to consult the manufacturer's installation guide or a professional mechanic. Proper installation is crucial for ensuring the safety and performance of your new braking system. This kit is a serious investment in your vehicle's performance and safety, offering a noticeable improvement in braking feel and capability.
