Brembo 04-10 5-Series (Excl. xDrive/M5) Rr GT BBK 4Pist Cast 2pc 345x28 2pc Rotor Slotted Type1-Red

The 345x28mm, two-piece rotors in this Brembo GT Big Brake Kit are a key component for improved stopping performance. This kit is specifically designed for the rear of 2004-2010 5-Series BMWs, excluding xDrive and M5 models, offering a substantial upgrade over the factory braking system. The four-piston calipers are cast from aluminum for a strong yet lightweight housing, which helps dissipate heat more effectively than heavier cast iron. This means you get more consistent braking power, even during repeated hard stops.

Brembo's GT BBK utilizes a two-piece rotor design where the rotor and the hat are separate components. This design allows for better thermal management, as the hat can expand and contract independently of the rotor surface, reducing the risk of warping. The rotors themselves are slotted, with Type 1 slotting pattern, which helps to sweep away dust and gas that can build up between the pad and rotor surface. This slotting pattern is chosen for its balance between performance and noise reduction. The calipers are finished in a vibrant red, adding a visual upgrade to your vehicle's appearance.

This kit includes everything you need to install the rear big brake system, including the calipers, rotors, mounting brackets, and high-performance brake pads. It's a comprehensive package for enthusiasts looking to significantly enhance their vehicle's braking capabilities. Remember to consult the manufacturer's installation instructions for specific details regarding fitment and setup for your particular 5-Series model.
