Thanks TJ. However, I am looking for the actual size of the boxes, not what the boxes represent. If you measure the box, it’s not actually 2mm on each side. The 2mm is only true as far as the measurement due to the distance between the snipers.
It strikes me that the 2mm per box rule wouldn’t really hold though as the deflection of the laser would be greater or lower depending on how far apart the lasers are. Like sticking it on the end of a spindle would make it appear to have more toe than if the laser were placed on the inside of the spindle. Or different types of spindle!
I guess what I’m wondering, if it’s 2mm per box where are the lasers located?
Evan, you’re correct that it isn’t an exact 2 mm measurement. But it’s close enough that any difference will not be extremely meaningful. Your best bet to provide the most precision is to take the measurements consistently at the longest distance possible (outside end of the spindle).
When the odds are that your wheels may not be “exactly” straight ahead, when the tie rod sees a tiny bit of adjustment when the ends are tightened down, when the kart flexes on the ground, etc. All of these things make having an exact measurement next to impossible.
