@ EarlQ,
All of the suspension nerds on here should read that paper. Not just because of the FAPs and jacking forces, either. Mitchell is the man, and he has a way of elegantly poo-pooing on everything you've ever learned.
My interpretation of roll center isn't horrifically wrong, but it isn't terribly useful either. Hopefully it will atleast serve as an elementary-level understanding for the next-level theory and kinematic simulations.
@ Ninjin,
A model is just that, a simplified and solvable interpretation of reality. A good model is reproducible and transferable. My sincere hope is that we can make something that anybody can validate for themselves and apply to their specific modification.
Ex: Somebody has heard that RCE Yellow lowering springs are the bee's thorax. They want to buy some, but would feel more comfortable knowing what the rear camber curves look like (since that's not factory adjustable). If we validate the base model, he can drop in the new spring rate and height... then be reasonably confident in the modest tire wear rates. Similarly, they could test the eccentric bushings, and see if that would correct the problem (before buying and installing them).
@ Ayau,
They have modelling, but when you're ballin' enough... you get big boy tools. 7 post rigs like this:

and shock dynos like this:

Even if it's a technician running the test and one experienced engineer calling the shots ... you can get a great setup. KONI and the rest have team of people on this, since it's their bread and butter. Just so it's said, 4 of the "posts" are the wheels, and the remainder are for the chassis.
