after market struts on e70 2009
 

I am using a 2009 e70 X5 3.0d. It has a DVD changer, CD player, HUD, Comfort access and rear entertainment (rear DVD) package.

I want the ride quality to be adjustable like i had with the PSS 9 on my e270 CDi.

I found out that KW have such a system. My problem is that my dealer told me that the my vehicle has regular struts in the front and electronic struts in the rear. KW guys say that cannot be so. but it is a fact:(

I want to have a ride quality adjustable setup. How do i do it? can any body help?
