@ChoccyNuts Hi, Thanks for your comment, yes you are right, but it does state that fact from 0.40 seconds into the first section of the video. Failiure to do this would indeed result in a poor set up. Hope this answers your question. All the best.
How do you account for varying track widths, as the track width changes across different cars the laser will move along the scale even though toe may be the same? E.g. 1mm toe in per wheel at a track width of 1500mms would position the laser at a different point to 1mm toe in at 1750mm track width on the scale and give you an incorrect reading. I don't see anywhere shown that you are adjusting a scale to account for wheel diameters as on the Dunlop type mirror gauges or anything that accounts for track widths. I must be missing something!
If the front camber or caster is unequal, then you will end up aligning the rear incorrectly. You need to ensure the front camber and caster is correct before you try and get the rear toe set.
When adjusting the front I can’t get the rear flags both equal (4) and the toe equal on both sides on the front. I have to have more toe on one wheel than the other to get the back flags equal or if I get the toe even on both wheels the back flags aren’t equal. What’s more important the rear flags equal or the same amount of toe on each wheel on the front. When the back flags are equal the total toe is in spec on the front but not equal, 1 wheel is toeing in 1mm and the other toeing in 2mm.
