Wheel offsets

[Peter Schulz <schulz@ed.ray.com>]

Can someone expalin to me how stock wheel offset is affected
when going to a plus 1 fitment?

The Borbets that tire rack sent me where spec.'d at ET 35,
which is correct for the stock sedan fitment, but the CQ
stock fitment is ET37.

does the ET change when going from 15 inch to 16 inch 
and 7 to 7.5 widths?  

I assume that it should when going to a wider rim, to prevent
that "low rider" wheels sticking out of the fender look.
