 Are Passat wheels the correct offset and is the center hole the correct
 size?  In other words, is this wheel, without modification, a 100% proper
 fit for the Vanagon? >>

No, the center of the rim is too small for the Vanagon hub.  I took it to a
machinist to have him machine the center out.  He would NOT touch the rim for
the liability issue.  The center of the rim has a lip (the thickness of the
metal) where the center hole is formed.  This lip stiffens the rim to keep it
from flexing, without it will crack and fail, that is why he would not touch
the rim.  He learned from his racing past, that it will fail.
