About a month ago I had the Eibach Pro Kit installed on my 2017 X5 35i (without Air Suspension) and I wanted to share my progress/experience with the forum.
During my period of research prior to deciding to go with Eibach, I found an abundance of posts related to X5's
with the rear Air Suspension, but a very low amount of posts specific to those X5's
without the rear Air Suspension. For those unaware, usage of the Eibach Pro Kit differs based on the presence (or lack thereof) of the rear Air Suspension, thus the reasoning behind this post.
For X5's
with rear Air Suspension, the front springs from the Eibach Pro Kit can be used to lower the front
ONLY, however in order to accomplish lowering for the rear, you would need to source adjustable lowering end links not included in the Eibach Pro Kit.
If you aren't sure whether your X5 has Air Suspension or not, F15 X5's with the optional third row of seating
have the rear Air Suspension while the Two Row (non 'M' spec) variants do not, unless spec'd with Air Suspension when originally ordered from the factory. In order to truly check, decoding your VIN is your best bet.
For X5's
without rear Air Suspension, the Eibach Pro Kit consists of
two pairs of lowering springs. One for the front and one of the rear.
My 2017 X5
without Air Suspension had the Eibach Pro Kit installed on May 10th and the following replies contain progress updates over a 1-month time period.
My hope for this post is that it will serve as a reference for any F15 owner
without Air Suspension that is considering the Eibach Pro Kit as a means of achieving a
mild drop.

Post Install Impressions
Ride is slightly different. It's hard to put my finger on, but it
feels like the amount of body roll has been decreased and that there isn't as much bounce and "float" to the ride.
