RH is Ride Heigth, not spring course. Most cars have similar spring course, since the wheels are more or less the "same sizes" (huge double quote there) and atrtached "on the same spot") (very huge double quotes).
RH is what is left on top of spring course anyway.
I often use RH * spring rates = the whole car in front, adapting rear SR due to weigth distrib, and adapt + or - same % if I feel the car is too soft or too stiff, it's a good starting point I was allready using in GT5 (I used RH from GT4 cars).
I'm programing a software for this, as I'm allready fed up with making Front RH* Front SR * rear weigth / front weigth...
The UI is ready but I have design problems. Got 4 sliders : RH (low to high), SR (soft to stiff), RH balance (low front / high rear to high front / low rear) and SR balance (front higher than rear to rear higher than front in comparaison of the weigth balance).
The problem is designing max values of the sliders atm esp SR, and how they will move if you touch one... All of this depending on the max/min RH/SR in the game, the weigth distrib and the weigth. It's a lot more complicated than I though.
And I don't even took aero in it
