Need help with setting the controller. (Grand Theft Auto 4)

Guys,tell me is it possible to change the controls? I want a machine that you can manage analogue,I feel so comfortable. But the gas and brake on the triggers, or bumpers,are confused in General,and turn on the analog,I'm not comfortable with. I have the controller but in Xbox,just using your set up,the game sees it,it's okay,but I don't like. Neither the first variant,where the management triggers or buttons,it is still not convenient.
