It's kinda hard for my to explain and I only use RWD cars, I haven't tried the AWD or FWD cards.
Before a turn, full throttle to get the ass end out and start turning in the direction your turn. Before the ass end starts to come around, turn the steering in the opposite direction. Then you have to modulate the throttle to keep your car going and to keep it sideways. Then to straighten it out, point the nose in the direction you want to go and be prepared to turn the steering in the opposite diretion to correct your path (but don't over-correct or you will spin out).
