"For accuracy? The problem is you need a level measurement at the center of your wheels on the front and rear. Your oil pan and things like your drag link will get in the way."
Jon, the tram bars we used for decades to measure toe back when lasers were the stuff of science fiction (Buck Rogers' ray gun, etc.) work just as well now as they did back then. They had a support bar that sat on the floor, and extendable measuring pointers that could be adjusted to spindle height. I've still got a whole system like that, including portable turn plates, magnetic caster/camber gauges, and a tram bar for toe measurements. All I need is a level shop floor. I think I gave something like $300.00 for the whole setup.
