Focus rims have the wrong offset.
FWD ("high") offset is like this, to make room for all the itshay they had to push to the outside of the car in order to A. be cheap and B. allow for a drive axle that also turns (whaaaat?) They are often like +55 (Honda) or even more (Acura).
RWD ("low") offset is like this, to make it look uckfayin' sweet and probably also to widen the track width of the car so you don't end up in a hedge you goddamn leaf-molesting pervert. These are like +25.
Zero offset is in like the
centre of the wheel. Can you go negative offset? Yes, if you are awesome.
Note that this is not always the case (for instance the Miata runs FWD-offset wheels), but it is generally the case.
"Backspacing" is American for offset, but you measure from the back of the wheel.
