But I'm going to throw something in on Jim's comments so people don't go
apples and oranges, I fully agree with his comments relative to any rear
wheel drive t1, t2, t3, t4 or vanagon, but this DOES NOT hold true for ANY
FWD car.  FWD vw's and all front drive cars should have hub concentric
alloys (or inserts therein) or wheels in general for proper balance and to
avoid eating front wheel bearings (sort of delicate things despite their
size because they have a rotating shaft though them instead of a static
spindle) and for generaly smooth running when you are also trying to apply
the power though the potentially turned wheels.  This gets more important
the heavier the wheel and the larger the diameter with more of the mass at a
greater radius from the hub.  This also raises a real interesting question
IMHO.  My old quantum syncro and any Audi quattro and I assume mom's (ugh)
Subaru has hub concentri wheels all round, but what of the syncro van???
Particularly with steel wheels which as Jim mentions are no where near
hubcentric on a regular vans hubs.  Do the front hubs on a syncro force
concentricity with steel wheels or is it maintained by the lug bolts as on a
standard van.  Truly bored minds want to know.
