Good point!
I just found w124 has front/rear track: 59/58.7 inch (1501/1491 mm).
So, adjusting like I mentioned would give me a slight toe out.
With a 2800mm wheelbase, I figure that's around 0.041 degrees toe out (per side).
To correct for that, on my 15" rims, the rim to string measurements would not be equal. For zero toe, I'd have to see 0.14mm more distance to the string at the leading edge of the rim, and see 0.14mm less distance at the trailing edge, using center of hub as the standard. Or more simply, I should see a difference of distances between leading and trailing edge measurements of about 0.28mm (about 11 thousands of an inch).
I feel this is within error margin of most string thicknesses and measuring tools. For a w124 I think "going for equal" is good enough, and maybe error on having smidgens more distances at the leading edge. ... considering I don't use a spreader bar which would force more toe out if it were used and we'd want to compensate for that.
