Right then, i dont confess to knowing anything about the Forester but if you use this offset, will the spokes foul the brake calliper? Or, will the the rim foul the suspension strut?
Just a couple of points i would think about.
You would be altering the "track" of the vehicle, will it cause a handling issue?
My only concern on a Forester would be excessive loading on the wheel bearings. I would think that the wheels being so outboard would cause the wheel bearings to wear very quickly indeed.
