Bilstein B8 Performance Plus Shocks Set - 2004-2005 BMW 645Ci RWD

The Bilstein B8 Performance Plus Shocks Set is a high-performance suspension upgrade designed for rear-wheel-drive vehicles. This set includes four monotube dampers—two for the front and two for the rear—that are engineered to enhance handling, stability, and ride quality. Constructed with application-specific valve settings, these dampers optimize vehicle dynamics when paired with aftermarket lowering springs. Each shock absorber undergoes rigorous testing to meet or exceed OE standards, ensuring durability and consistent performance. The dampers feature a monotube design that provides improved heat dissipation and responsiveness, making them ideal for sporty driving and improved vehicle control. The package includes all necessary hardware, such as washers, bushings, reservoir clamps, and nuts, for a straightforward installation, with factory shock mounting bolts reused. Bilstein’s limited lifetime warranty offers added peace of mind against defects and premature failure.

Designed specifically for the 2004-2005 BMW 645Ci RWD models, these shocks are a direct replacement for factory units, providing a performance upgrade for street and spirited driving. They are compatible exclusively with rear-wheel-drive configurations and are intended for use with aftermarket lowering springs to achieve a sportier look and improved handling. The kit includes four shocks, with mounting plates sold separately if needed. These dampers are suitable for enthusiasts seeking enhanced vehicle responsiveness, cornering stability, and a more aggressive stance. Installation involves reusing factory hardware, making them a convenient upgrade for owners looking to improve their BMW’s suspension performance without extensive modifications.
