While working on the brakes (2004 X3 non-sport) recently, I noticed that one of the rear coils was broken. I did some brief research on the internet, and found this is rather common. ??? Really? Next day I started working on the other side and noticed that spring is broken too. Two broken rear springs? I can't believe it. This X3 has never seen off-road and has lived a tender life. So, I'm looking for experience in replacing the springs. Do I go with stock or look at aftermarket (cheaper. better?). I'm cautious about stock - why won't they break again? Looking at Eibach Pro-Kit. Any experience? Is the process of changing the springs easy enough to do in the driveway with above average mechanical skills? I noticed that I can't use a typical spring compressor to remove the coils as there's no room. Internet research shows that most folks have used pry bars to get out and in. That doesn't seem to be the best way to do it. ??? I've jacked the vehicle up, removed the wheel/tire, dropped the axel, removed the shock and it's much lower, but still not low enough. Suggestions? Sway bar links? What else will get it down lower without too much work but still keep it simple? Thanks for your thoughts.
