Actually, things like geometric roll centers and anti effects all vary with ride height. It's not that the curves for any of those things plotted against ride height have changed, just that you're operating in different regions of those curves once you lower the car. Or raise it up, for that matter.
As an example, it is entirely possible with some suspension arrangements for the anti-squat % to drop slightly over the first inch of rear suspension compression (squat), before turning around and increasing with still further squat. Even stranger curve shapes are possible, but at least the odd variations in the middle are relatively minor.
Is it true some of these anti effects causes undesirable behaviors? I have heard of WRX understeers on power during corner exit because of anti-dive. I don't really understand how they are related but Whiteline has a kit on the market to eliminate anti-dive for that car.
