Offsets and et numbers - help I'm confused

[hot66]

just read vujade's post, & he is also correct in how to work out 'back spacing', or mounting face to inner wheel lip.

I think the confusion lies in what people actually call positive or negative. I don't think this really matters, as long as you know the 'et' & the rim width then you can work out if the wheel will fit.

Just make sure the company you buy your wheels off is talking about the same dimensions
