ok, people keep talking about wheel offset, but what is it. I know about stud patterns and height and width, but what is this offset you all speak of, and how do I know what to buy and how to find out what offset is what on 2nd hand wheels?
thanks heaps, zep

Offset is the relative centre of the wheel in comparison to the mounting point, i hope i worded that right... Hence its offset from the centre, but the engineers have designed the wheel to sit that way, so to check offset there is generally a label of ET25, for example, would be a 25mm offset. Check the rims you're buying for this... Hope that helps ya

adding to that also it stops excessive stresses on the axles/bearings, etc, a mate of mine changed his offset too much and fucked his bearings and had heaps of trouble trying to allign it before the bearings went...
