LegacyMode problem...

[pnvv]

I built this car today, but the ride was really bumpy so I added suspension. However the hinges would start to vibrate when the car was driven quickly so I reduced the legacymode to 0, but then the hinges for the wheels started acting like HingeConstant was extremely low. Is this a glitch or is there a way to fix it?

There are few ways to handle it:
1) Increase Sim.limitAngVel (could be not safe)
2) Increase Sim.frequency
3) set legacyMode=0 and increase density
