I bought my kit from fcp Euro. Not sure if these are the sport or hd bilsteins, but they looked exactly like yours. Springs should be sport (I don't think they have the "race" version for the x5). Mild drop. Good combo package for converting from air suspension.

Thanks for the inspiration to swap my suspension. I've been putting it off since I bought the vehicle 3 years ago. Felt bad to scrap a perfectly good air suspension, but at 120k miles it was about time for a refresh. Was on the fence with getting the bc coilovers or just getting a spring /shock combo. Glad I went with the bilsteins. Install it and forget it. No need to make adjustments
