I've heard that lowering springs will create horrible negative camber and cause excessive tire wear. Is this true? I would like to get some good springs and get the stance on my Xi just sitting over a set of 19" rims and tires...any recommendations??? I love the look of the 3 series with the sport package on them and that's the look I want to achieve. Anyone ever use Bavarian Autosport springs before...they seem somewhat inexpensive. Thx!
