Hi - I was wondering if anyone had experience with installing H&R Springs (part #50469) on an F07 with X Drive and self leveling. What I've seen mostly on sites is for the 535 which appears to be different. I'm good with wrenches and work on my 325xi and a 540. It looks like most people who have other cars have mechanics do the springs but springs are usually good candidates for the DIY'er.

Any thoughts on the value, performance, and DIY-ability for lowering my F07?

Thanks!
Erik
