Offset gets higher the closer in the 'hub' section of the wheel is, right? however, what part of the wheel is that measured from? center? outside edge?

Wanting to know so that I can try to figure out based on the stock spacing, how far it'd be to clear, on a given width wheel.. etc.

This offset thing has always been too vaguely defined...

How is it vaguely defined?

Offset is the distance from the backpad of the wheel mounting surface to the centerline of the wheel. It is measured in milimeters.

That's a damned accurate definition.

It's not so much the offset being vaguely defined (it's not; as mav1178 has pointed out it's a well-defined measurement) as it is that people have been a little vague about what they want (some want flush, some want jutting, etc.), and that there is typically a "range" of offsets that will work.

If you want all the info you need in terms of things you have to measure and calculate to get acceptable offsets, try:

It's info written and gathered by RX-7 guys, but much of the technical info is car-agnostic.
