If the drag link isn't level, there will be bump steer- - - -no way to avoid it. Even from a level position, once the wheels leave a straight ahead position, some bump steer is going to happen. The best of all possible situations is to minimize it. Most people just learn to live with it - - - - -the further away from level we start, the worse the problem will be. I don't know of any baseball player who would willingly step up to the plate with one or two strikes against him from the get-go. Maybe that kind of logic escapes the hotrodders who think they can violate the laws of physics without any consequences.
