Bilstein B8 2004 BMW 645Ci Base Front 36mm Monotube Strut Assembly

This is the Bilstein B8 Performance Plus front strut assembly for your 2004-2005 BMW 645Ci. It's built to work with lowering springs, giving your car a sportier feel and improved handling without sacrificing too much comfort. If you're looking to pair new lowering springs with a damper that's specifically tuned for them, this is a solid option.

Bilstein uses a monotube design in these struts, which helps them manage heat better and maintain consistent performance, especially when you're pushing the car a bit. The valving is set up specifically for performance applications, meaning it'll work well with the reduced ride height and stiffer spring rates that come from using lowering springs. It's a well-built part that's rigorously tested to meet or exceed original equipment standards, offering a noticeable improvement in how your car handles.
