I found a Excell program that I downloaded and am playing with. You get to type in all the specs of your car, and it gives a graph of wheel angle difference with rack movement. It also gives a graph of what the graph should look like for optimal handling, acording to the programer. I think it is quite good, because it takes into acount wheel slip angles (front and back) and placement of the rake behind the wheel center distance.
There are so many angles all working at once in steering it is mind boggleing. Very few people would have a full grasp of everything that happens. After a sleepless night and experimentation with both 100% and 0% ackermann, I am going to go back to almost factory spec ackermann angles, or a bit less. It depends mostly on front wheel slip, but it seams about 50% ackermann is good on a road car. Even if the knuckles are parallel, this can also be achieved by mounting the rack further back (as it often already is on many cars). I am not changing the ackermann simply for the ackernamm effect, but for the side effects these things have. Because I need quick steering, and I need good handling at low speeds, and I need strait line stability, and I need to do tight u-turns.
Most webpages that mention this miss out on alot, but some are good. Most are theory, because sadly few have actualy experimented.
Let me know if anyone has questions.
