Problem with some physics in a car game


We are programming a Car racing game but we got some problems with driving.

The car often turns upside down while driving around a curve and sometimes while driving over a brink. also the car jumps really far and really high.

we hope somebody got a tip/command how to change/correct that.

thanking you in anticipation

Make sure the dimensions of your model are correct (1 unit = 1 meter, if its too small it will look like a toy car) and try to lower the center of mass (described in the wiki).
