remember you get lateral weight transfer when rotating the car and the problem is how to "share" the effort across both front tyres.
I actually think that SPL have it "right" .......
As the car rolls onto the outside front tyre with weight transfer, the effect of the FUCA with increased lock puts more weight onto the inside tyre and so it is able to share more of the available grip rather than letting the outside tyre do "all the work".

Thanks for the reply, you may be correct. But my thoughts are along the following line: in order to increase the actual weight over the inside tire the car has to actually
push into the ground harder... and to generate a force its got to be pushing against something else. And the amount of weight transfer is
only affected by the CG height, track width and weight of the car. All other factors just affect the roll angle attained. I'm thinking that just because the car raises on one side, that doesn't mean its pushing into the ground harder, the only factor changed by the weight transfer would be how hard it has to work to raise one side of the car or another. ...Or would that force possibly even be transmitted back to the outside tires via the roll bars and springs? My head is starting to hurt.
Admittedly though, only in the very tightest of on track corners would this effect possibly be significant I suppose. With its noticeable effect on the steering weight and self centering I was also considering if it would contribute to almost a pendulum like effect with larger quick corrections; which seems to be something I do feel a bit of. Tough to say.
jchammond I would say I've tracked the car quite a bit but I still like to ponder some of these more difficult to measure things (especially while I don't have access to my car or track time) and was just looking for other's thoughts about it. I agree about SPL, have several of their products on my Z
