[Spits] [TR] GT6 Bump Steer

[Chris Crisenbery]

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.
