If your car flips at high speed (very spectacular... seen some flips like those ones who made the Mercedes at LeMans) could be caused it gets air on the underside.
Put your body as lowest possible and near of the surface (doesn't matter if it scratches a little at first time) to avoid get air and go airborne (brute landings aren't the best friend of your car).
If your car rolls to the side during turning, is called traction roll, this could be solved tunning the suspension and anti-roll bars of your car, please, ellaborate what's happening with your car.
P.S: Pebbles and small stones could cause you to go airborne too.
