+1 on what dan said. I'm running Eibach sport lines (the lowest of the two). You can see sort of what it looks like in my sig or better yet here in this pic. I am satisfied with them although they definately need a set of struts with them. As far as the back sitting lower than the front, most springs are made like 1.5" drop up front and like 1.2" in rear to compensate for the different height of the front and back of the car. Maybe I have the numbers backwards but either way the front and back drop height should be different. I think the SPortLines are a cheap way to go to improve the looks and handling of your car.
