Brembo 05-08 7-Series (After 3/05 Prod) Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled- Yellow

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 on your 2005-2008 BMW 7-Series, specifically those produced after March 2005, this kit is engineered to make a substantial difference. It replaces your factory rear braking system with a more robust setup designed for demanding use.

This kit centers around a pair of yellow 4-piston cast aluminum calipers, which offer increased clamping force over stock calipers. These calipers work in conjunction with 345x28mm two-piece rotors. The rotors are drilled, a design choice that helps dissipate heat and expel gases and dust from the braking surface, leading to more consistent performance, especially during repeated hard stops. The two-piece rotor construction also helps manage heat and can reduce unsprung weight compared to a single-piece rotor.

When installing a big brake kit like this, it's important to consider that it's a significant upgrade. You'll want to ensure your brake fluid is fresh and that the system is properly bled to take full advantage of the new components. This kit is designed to be a comprehensive rear brake upgrade, providing a noticeable improvement in braking feel and performance for your 7-Series.
