Race up to the nearest purple obstacle and pause the game when you are only a little distance in front of it. Quit the race and your swoop will drift a little bit into the obstacle and then receive a speed boost. The race master will say that you got a time around the time where you quit the game, and if your time is low enough, you will win first place.Note: This will not give an instant win on Nar Shadaa, as you will have to take care of the unbeatable droid racer first. Otherwise the droid will beat your time no matter how low it is.
