No I have not yet been able to rid myself of the wheel-bending problem as you turn corners at high speed (I noticed the buggy_demo has the same 'subtle feature').

I tried (each sim step)...
- dBodySetFiniteRotationMode()
- dBodySetFiniteRotationAxis()

It reduced the problem but did not remove it completely.

I tried different combinations of contact values ERP, CFM & slip, also gravity, I have not yet try different wheel/body mass & geoms.  All my changes either increased or reduced bendy wheels but did not remove it.

The problem is that bendy wheels make my 'car' impossible to control ... it looks like someone attached the wheels with a rubber band ... hilarious fun if thats the sort of game I was trying to write ! :)

(russ/ode_users?) Why is it not possible to totally stop the hinge2 'axles' becoming 'bent' ?
