I know an old video, but does anyone know how to convert the mm reading from this to degrees? when car makers spec toe they do it at set points, so for example at the rim on a 15" wheel the toes can be 2.4mm, 16" 2.5mm. so toe mm is at a designated point, whereas degrees is not. on these gauges, is the toe reading at the laser heads and you have to work back to either the tyre face or rim?
