Usually you can't measure directly from 3 o=E2=80=99clock to 3 =
o=E2=80=99clock, or 9 to 9, anyway =E2=80=94 there is all sorts of =
hardware in the way. So you are dropping a vertical to the ground from =
these positions, and measuring the distance between that pair of points. =
And because of flex in the sidewalls, you really should lift the car off =
the ground and set it back down after every adjustment, or have the =
tires on a frictionless surface (which of course needs to be absolutely =
flat and level, in any case). All of which adds so many potential =
inaccuracies of angle and measurement that I would expect the errors =
would overwhelm the data.
I have done it, but merely as a sanity check after front end work. Then =
I have it professionally aligned before I wreck a pair of tires.
