I generally prefer to post to existing threads, but the closest to what I wanted to discuss is in a thread that is over 10 years dead. That's a pretty old horse to dig up.

So here goes with a clean shot. I do know that the Ackerman Principle is said to be the least of suspension sins, but I want to understand how it is applied.
Here's my question: Isn't it important to consider the KPI, and where it points to on the ground, rather than just go by the top center of the kingpin itself? That is, if the KPI points to the center of the contact patch (which I understand to be in general the ideal objective), shouldn't the line running thorough the center of the idler arm & outer tie rod end back to the center of the rear axle be aligned with the point on the road surface where the KPI points?
(This may sounds like a stupid question, and maybe it is, but if I don't ask, I stay stupid.)
