With a heavy car, you need harder ground - this makes sense to me. :-) I
think you can get the same effect by removing those two lines entirely,
and also remove the "dContactSoftErp | dContactSoftCfm" flags from the
surface.mode variable.  I don't use them in my application either.

What values are you using for the contact friction?
