We shortly decided to lower the vehicle. We ended up using e9x components as there aren't much selection for x1. The sdrive is nearly identical to the e90 red with exception of a few things. Below, we installed e9x knuckles with e90 koni yellow. I purchased e92 335i D7 spring as they are the stiff oem and used e93 m3 rear spring in the rear. We also installed 513m wheels from an f80 m3. I initially installed ST shocks from their Coilovers kit, but felt they were too soft.

For the most part, this set up was great for the daily purpose in terms of ride quality and feel. I was pretty happy with the height as well.

NOTE: the e90 knuckles are 1.5" lower than x1 knuckles
