Yet driving WELL below the limit of the stock re92s, her flaps grind into the ground. Obviously, that must be due to bushing flex and must be a rather large amount. Mainly I'm just curious, I can't see any practical value for the information.

Not easily, no. Sorry. Not even some really expensive car modeling programs can do that! If you just wanted to guess and estimate, you could add bushing flex (in inches) to the "tire deflection" cells in the spreadsheet. For ground clearance, though, don't forget: roll is just one part- you have to allow for the inevitable bumps in corners, too.
