Set the drift mode option to "RR64". Begin a game and get to a sharp turn. Stop accelerating, turn the opposite direction from the turn, and accelerate again while still turning. If done correctly, your car will spin around during the powerslide. After you are turned around, control the car as if in a normal powerslide and re-align it with the track. This trick allows your car to get through winding turns without braking or losing speed.
