Thanks to everyone who responded. I think I am going to get
the coilover setup. I would rather have the adjustabiliy then to find out later I don't want my car that low and can't do anything about it. I saw an M3 with the lowered look I am looking for a few weeks ago at a performance shop here so I think I'm going to try to track it down and find out what was done and how the car handles and rides.
