It was bad enough that it took me a few practice runs over counter-steering to keep the car in my lane.

That said, my 350z may have been an extreme example of what can happen. That car, having never been in any accident or anything, was not a very true chassis. The passenger side wheel/tire sticks out from the fender more as if the wheel was a more aggressive offset by a VERY noticeable amount.

So I would have to say that I might be getting to sensitive about the issue.. I only know that in mechanical theory, it is incorrect to do. But in practice, with my limited suspension setup experience, it may take a very extreme case before the effects are noticeable to the driver.
I think you hit the nail on the head with the large amount of travel comment.

With a track prepped car, the suspension travel is reduced significantly from stock, to say nothing of a drag setup.

I would imagine that pro race shops (Like Doran) probably manufacture their lockout hardware taking these issues into account so that they have proper positioning as a "base" rather than using an eccentric to adjust it, if you understand what I'm saying. Then, they just use the adjustable arms to zero in the settings over the life of the car.
