So I think I ran into the problem you're experiencing on my X3 35i. I replaced the factory struts with the Bilstein B6 struts but the X3 had the factory base springs.

The ride feels exactly how you were describing. But in my haste, I overlooked the B6 saying it's designed for the S226A Sport Settings:

Well, I don't think recall the S226A Sport Settings being an option in the US for the model year of the X3. You either had to go with the base suspension or the Dynamic Handling Package.

I had my dealer (BMW of Annapolis) look into this and they were able to square me away. They found the part numbers for the springs of the S226A package which were for a car withOUT Electronic Damper Control.

Those springs get here by Tuesday/Wednesday and it'll be a few weeks before I get to install them.
