To change any of these relationships will result in faster tire wear and less traction since one wheel will be forced to be in a slight slip state in a turn. Both tires will not be tracking correctly. If you stay on dirt or keep it parked, no problem.

Those are the same results that you get by using non-factory tire widths or different wheels. Lifting the front on IFS has other effects on the steering as well.

It is all relative.
