Well, I am going to research the possibilities of doing this to my wagon. Most of the suspension components of the X1 E84 are the same on the E91 according to realOEM. I'll probably start picking up parts from the X1 on ebay for cheap and using a little visual engineering. My main "humph" moment is why aren't springs listed in realOEM? Is this because the springs are a third party product that BMW just uses?
