From what I can see, I am not completely sure what you are doing wrong. The best advice I can give is to try changing the position of the wheels in MED and see what happens. I'd really like to see this in action. If you cannot solve it please either upload your wheels and chassis models online, or send me a PM and I can help you via email(send it through email). I currently dont have anyway of hosting pictures online right now, so I cannot post a picture of how I line my wheels up.
