That's odd that you would roll them over. I suspect you were just getting positive camber due to body roll, if you're stock. I don't roll at all at around 30-34 psi. Having the rears softer lets me run all sorts of rear stiffness and keep the rear end from being tail-happy. I'd much rather have more grip and less rotation than the other way around. Rotation feels good, but grip is faster.
