Ride height na vs nb

apple

So while setting up my car I was thinking about ride heights, assuming hub to fender measurement. There is a lot more info for the NA vs the NB so assume the info is from a NA. But, if the fenders have different openings, the NB could be a little more open, a given ride height for the NA could actually be lower if measured the same on the NB. Meaning a 12quot; ride height could be fine on a NA but be too low on the NB due to a larger fender arch.
Does anyone know the correlation between the NA and NB ride heights?
I put the thread here but may be more applicable in the autocross forum if I don't get a answer.
