[ODE] wheels, still

[Jon Watte]

Setting ERP as low as 0.007 almost turns off the constraint/joint 
entirely, so I wouldn't recommend that. You can have wheels working 
just fine without that. I hate sounding like a broken record, but 
did you read the carworld source?

Cheers,

Hi there,

Try setting dParamStopCFM to 0.0001 and dParamStopERP to 0.007. I've had
problem with my wheels, but they were starting to rotating like crazy in
direction perpendicular to their rotation axis :|, something was braking
joint limits, but those settings solved this problem (for now :D)

However, now i have problem with lowering center of mass of my vehicle
chassis (represented by box), anyone could post exact function calls doing
this?
