Brake into the turns to get it sideways and feather the gas to keep it away from the wall and maintain the drift, don't jam the gas until you're passed the apex of the turn. If you initiated the drift too early then let go of everything (I use the dual shock controller so I just take my fingers off everything), the car should keep the drifting in a straight path.
