Brembo 05-08 7-Series (After 3/5 Prod) Rear GT BBK 4 Pist Cast 345x28 2pc Rotor Slotted Type1-Red

Brembo is well-known for making high-performance braking components, and this Rear GT Big Brake Kit (BBK) is a prime example of their expertise. If you're looking to significantly upgrade the stopping power and feel of your 2005-2008 7-Series, especially those produced after March 5th, this kit is engineered to do just that. It replaces your factory rear braking system with a robust setup designed for improved thermal management and consistent performance under demanding conditions.

This kit features a pair of cast aluminum 4-piston calipers, which offer more clamping force than typical 2-piston calipers. They work in conjunction with substantial 345mm x 28mm two-piece rotors. The rotors are slotted with Brembo's Type 1 pattern, which helps to vent gases and dust away from the pad surface, maintaining a cleaner contact patch and reducing the chance of brake fade during hard braking. The two-piece design allows the rotor hat to expand and contract independently of the friction ring, which can help reduce stress and prevent warping over time.

When installing a kit like this, it's important to note that it's a significant upgrade over stock. You'll likely notice a more responsive pedal feel and improved fade resistance, especially during spirited driving or when carrying heavy loads. While this kit is designed as a direct replacement for the specified 7-Series models, always refer to the manufacturer's installation guide for specific details regarding hardware and any potential modifications needed for optimal fitment and performance.
