Speaking of Wheels . . (Fuchs).

The nit that I do see in this thread is that there IS a difference in a wheel with the proper offset and a wheel with a spacer.
Wheel offset is the relationship between the wheel center line (rim) and the hub.
Using a spacer moves the entire wheel out from the wheel hub (out ward)

The real question is whether a proper hubcentric spacer and wheel would cause extra loading on the wheel bearing.
Possibly, but doubtful, especially if the tires are within the confines of stock diameter and the wheel well.

On the other hand, if you go to an undersized wheel that sticks waaaay out of the fenders...

My two pfennigs.
