Maybe it would have been better if I said rocker panel height. But then again, the point was that for a non competition car it is essentially irrelevant.

The equation is right. What you are missing is the tire - the equation assumes that the grip is available, which it may or may not be. If you want to try and determine if grip is available, you need to look at tire sensitivity. Oddly enough, if the tire is senstive enough that cg makes a significant difference in grip, it would be easier and more effective to put on a wider tire.
