Good to know. I didn't realize most of that work was for the one-way front. I just acquired a new DC oneway for my XX4 and it was a straight drop-in. I think they have something for the X5 ready or in the works, too (or the XX4 one will work).
I have been teetering back and forth on an X5, and the costs have been the main issue, plus I'd like to get more time under my belt with the XX4we. I have a 70% complete XX4 parts car that I picked up on the way, I just may have to dive into the world of the X5.
Awesome review, Jimmy. I appreciate the massive time and effort you put into it.
