changing form "toe in" to "toe out" but IN THE REAR OR THE FRONT?
You can have Ackerman, you can advance or retard: depending from the geometry of the steering train (english native talking people, help me with this!)
I don´t get what you mean with anti-ackerman
Also, you should setup Ackerman depending on, first, the type of car (with or without aero load, weight distribution, FWD/RWD and tyre characteristics) and track (smooth asphalt, gravel, mud...), then it depends of the driver "feeling".
