When the race begins, immediately turn around and drive into the concrete wall. Your car will keep bouncing off the wall, but keep driving that way that until you go through it. If done correctly everything in the course will be now be reversed, including the signs, track, and name on your car.

Reverse 360 Powerslide:
Set the drift mode option to "RR64". Begin game play 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.

Golf Caddy car:
