With stock spring rates I think the aussie bar is actually too soft for auto-x. I think it approaches the limit on road courses though. I would really like to play with two sets of aftermarket springs to get the car to balance better. For a while now I have been considering eibach fronts with h&R rears, tuning the handling solely with sway bars is really not the best way to do it. It will transfer lltd, but it ties both sides together which is cdetainly not a good thing.
