I have been reading threads on recommended alignment specifications for the Elise/Exige platform and I am left wondering how the community is measuring their toe. Toe is an angle of measurement (ie. degrees or minutes) and providing a "linear toe" specification without reference to the method of measurement means nothing. If I measure 1mm toe on a 24" toe plate you will have a completely different toe measurement than if I am measuring 1mm of toe off the 17" wheel rim (ie. string method). Heck even 1mm across a 16" wheel is more toe than 1mm accross a 17" wheel, though the difference is insignificant. So basically when people offer up "linear toe" specs what is the assumption?

Product Rectangle Font Line Material property

Some numbers to illustrate the differences, if you note Toe Plate (TP) Total toe compared to Wheel Diameter (WD) Total toe. I prefer measuring in mm as its just easier math when actually doing the alignments.

From Lotus service notes:
"Alignment is measured either by the angle a wheel makes with the vehicle centre line, or the difference in
dimension between the wheel rim to wheel rim measurement at the front and rear of the wheel at hub centre
height.
"
Thank you, just wanted to make sure I was speaking the same language.
