If you have a v6, leave the stock bar on. It's pretty large already, but swapping it out isn't really going to make much of a difference with your handling.
Better off upgrading your strut bar(s) and leave it at that.
However, if you are set on the Eibach setup, I have the Suspension Techniques F/R sways that are in new/like new condition.
Well, I will probably be doing it after a while. I just wanted to hear how much it helped with handling. Wheels, tires, konis and sport lines and a rs and front strut bar. I think thats all I can do for handling.
