FWIW steering stabilizers aka "bump steer kits" are not that uncommon in SS racing with stock front ends. We have one on the Vette as we cannot make it happy any other way and we only have 1/8" of toe change through the entire range of movement of the front end. But it is a 100% stock parts front end steering box control arms and all. We have massaged mounting points a bit to aid in the toe issues.
