As the suspension travels up and down the toe changes due to the different arcs involved between the upper and lower a-arms and the steering arm. If you really know what you are doing this toe change can be sometimes useful to help steer the car, other times it works against what you are trying to do. I suspect on a street car with DOT tires you might not notice that the wheels are pointing in different directions as you travel down the street, if the bump was really severe maybe the car might be a little darty on bumpy sections.
By shimming the rack, or if you are willing to put heim joints on the steering arm instead of tie-rods you can preety much make the tires travel up and down without any change in toe. ___________________________ Christopher E.
