I guess what I was trying to say is that the change in direction over larger
bumps encountered by only one wheel is more pronounced then when the car had
stock springs. May be due to stiffer springs and not the spring height. The
tierod arms set at about a 10 degree angle.

Geometrically speaking, bump steer will be minimized when the tie rods are
level, i.e. the wheel moving up or down will have the minimum effect on
steering. Of course, it is possible that some bump steer is desired and
you are trying to CONTROL it rather than MINIMIZE it, but I don't know
about that.
