The "moment arm" does connect the roll center and center of gravity, and both of them move when you move the ride height. Only the roll center will move if you change only the setup.

It is possible to change the setup in such a way that the car squishes up at 21mm ride height. Just put enough washers/spacers (like what I did in my vid showing roll center) and push together at the tire base and that will be the effect due to raising the roll center so high above ground. In that case, the center of gravity didn't move at all, so the test is not really showing anything about the center of gravity if you think about it.

You should just call me before somebody complains we're too off topic
