higher center of gravity wud cause the forces present during cornering to create a moment force(moment force depends on distance which is height here),so higer CoG can create enough moment force to flip da car...tire provide friction during conering and insufficient friction can send u in understeer... u wud generally experience understeer when u take a turn too fast but a turn TOO fast,u r fliped over....lot of factors determine stability..google abt it..
