Hi Ian
I totally agree about datum s being measured from. BUT my interpretation from the diagram referenced above, is that the datum line is NOT the ground and thus the silly need to go about things backward. More of a brain teaser for me, as i think for 99 percent of people, the fingers between tyre and wheel arch measures are close enough, but as with besser i am interested in other ideas. Cheers Darryl
That's my interpretation of the diagrams... but it doesn't really matter. As I asked before ..as Mr Bridger might ask "for why?". Reading the measurement methodology ("Raise the vehicle and support it parallel to a level floor using the comparative measurements..... ") suggests that these measurements are not intended in any way to set ride height but to determine body shape/alignment.
If you're only interested in setting the height then the best way is to choose a wheel clearance at a front corner (horizontal drive shaft is a good place to start) then corner weight all 4 wheels... Bob Holden used to advocate jacking the back end up more than most people would accept to improve handling....
Cheers, Ian
