In my 10+ years as a pro tech, I never saw a VW spec for any more or less than
80#.  My wheels are torqued at 80, and if you ever have had a flat on a cold,
wet december then you might be smart to get back to Sears and have them
retorque the wheels-I would stick with 80#- but anything up to 95-100# would
probably be OK.  Over torquing results in warped rotors, damaged wheel holes
and calling a tow service at 4 am when you cant get those last two nuts off.
imho
