First, turn on the running line, and unlimited fuel and tires. Qualify as you would for any track. During the race, when the running line turns red, wait a moment before letting off the gas. Then, press the gas when you reach the green again. The car will automatically go high, and the other cars will slow down. You can go around them. It may take a few laps, but eventually you will be running in the front. This tactic can be adapted for all short tracks.
