limit car collisions

Hi,
I’m trying to develop a car race game, but I have a big problem managing car accidents at high speed:
cars flips on the air (I’d like to have a minimum response on xz axis)
Which could be a right approach?
Thanks in advance
bye

I’ve seen that angularDrag and drag parameters are what I needed.

Sometimes anyway cars jump over the stratosphere, I’ll try to discover why
