Chris, Volks,I have been studying this topic for some time as I as well want
larger wheels. I must say in defense of Michael Sullivans post on the geometry
issues, to me the case he presented on geometry was very compelling. Irrespective
of how things can "feel" Chris, if the geometry of the vehicle has been changed on
how it plants itself on the ground, even a few millimeters, the handling
characteristics can be greatly altered. The strength of the wheel is not the
issue, and I'll bet those road rallies you are referencing we not conducted in a
Vanagon, but rather in (on) the vehicles those wheels were designed for.
I think we all know the Vanagon is not the best vehicle in a tough crosswind, I
would not want to do anything to exacerbate this characteristic. If Audi or MB
wheels -decrease- the effective wheelbase, -and they do-, this can only make this
issue worse and as Michael said, even dangerous. Cornering as well.
Remember, the "teknokraut" engineers in the Black Forest spent a few days or
better figuring the best wheel offset for the best overall geometry for the
Vanagon under standard conditions. Changing this in essence takes the vehicle out
of the known standards of handling that the VW boys put the Vanagon through to
determine it a "safe" handling vehicle under foreseeable conditions. There is a
very good reason for the offset on the wheels that they chose.
-I'll- reiterate, a few mm changes in offset -will- change the geometry and
handling of the vehicle noticeably.
Can you use other offsets for wheels safely? I would say, personally and
non-engineeringly (is that a word?) that the only offset I would personally select
would be one that is -greater- or "wider" than original. This would in essence
give the vehicle a wider "stance" and (possibly) greater stability, but again you
will run into the area of the unknown. But in the case of wider off-set, this
unknown area would be erring on the side of known standards of making vehicles
handle better, that is: lower/wider handles better than higher/skinnier vehicles.
Thanks Michael Sullivan for that very good data you provided, it was eye opening
and irrefutable IMHO.
My $.02, however this $.02 has cost me considerably as I am ceasing my search for
MB/Audi wheels, and are less expensive apparently than Winkler or other properly
designed wheels. Anyone know of -wider- offset wheels that will work on our
Vanagons?
