Eibach does make a nice Pro-System Plus Kit with the springs, Damper/Shocks, and anti-rollbars. They are around $900 from Tirerack.com.

It kind of helped me make up my mind. There is a guy who goes off in it, but just look past that one part of the post. I've decided to go with Eibach Springs, Tokico adjustable, BMR adjustable panhard, and some sway bars.
