How do I make cars roll over properly

[blacklemon173]

I'm trying to do a stunt scene in the Director Mode but can't make the cars flip over "Hollywood style".
I tried placing ramps with the scene editor and it helps launching the car sideways most of the time but they always just make half a flip and either land on their roof or tires and just slide away. It's as if the tires itself weigh half a ton each and keep the car from spinning.

Does anyone have some tips on how I can get decent looking car roll overs?
