Experiment on a single track and see back to back what happens. Change only the roll center at one side of the car and reset all other parameters like camber downstop and toe at the same values. You'll quickly find out how the feel of the car changes.
Unfortunately nothing is always the same. So sometimes you really need to try stuff all over again on different tracks. The "theory" is only that!
