My old friend Bruce Cambern, retired head of Ford SVO designed the last suspension on his 427 Cobra on his home computer, And his theories worked.
I never thought about it that way but yeah in reading the little bit on the ackermann principle in racing with suspension rebound and what not they control the toe and that is all I use see it as, but if one toe is more or less than the other THAT is part of the ackermann principle so where I use to think of it as simple "bumpsteer" the experienced engineer is USING this "flaw" to do what he wants, very interesting.
