A genuine plot on an aligner.
I can see the ackerman a few pages back now, but as stated in my post, please measure ackerman at all steering wheel positions, not just MAX lock.
Lock to lock ackerman will be identical, and if the car is aligned it will have 0 at center too, but measure the dynamic, I suspect it will grow and shrink on the each side independently.

Ha, sometimes it's not all about the graph man. If you have both ends of the tie rod parallel with both ends of the FLCA, there will be as little bumpsteer as possible. Obviously bumpsteer changes with steering lock, but there really isn't any way around this.
I'm pretty sure you're confusing ackerman with toe and dynamic toe? There will never be any ackerman at center, on any car, ever. And of course changing ackerman will change dynamic toe, they're basically interchangable. It's a pretty simple curve of the tie rod end, nothing crazy.
So the above is a kit to make FLCA's like the PSM ones I take it? Except with modified stock arms and bearing cups for the ball joint ends, yeah?
Just to let you know, Ikeya Formula was the first to design arms like that.
