It can be difficult to get one million points in one drift in endurance races. To get easy points, hold X + Circle. While holding those buttons, swing your car left and right on the more straight parts of the track to keep the drift going. If you begin to lose too much speed, release Circle and press X firmly to get some speed. Keep the car away from the walls. Once you get your speed back, hold Circle and complete your drifting.

Once the World Class League is unlocked, you will be required to make a profit of $200,000. Go to this event, and spectate Air Trauma. Bet on Crystal; the odds are 20:1. At the very beginning of the race, cheer (R1) for Crystal, and she will get a full nitrous bar. Make sure the person in front of her loses their nitrous every time they gain it by booing them (L1). Keep doing this until Crystal has passed everyone including the leader. If she wins the race at the end of 16 laps, you will win six million dollars.

For easy wins, always get cars that have the max class for the class you are in. Prototype mods are always available if you unlocked them. For example, if you are in Class 1, buy a car that has a max class of 1; it will usually win the race.

In Last Man Standing challenges, at the start, wait a short time after the race begins before going anywhere. After about three seconds, go and catch up, but do not pass. Instead, stay behind them. Spook each racer one at a time. This will cause them to spin out and hit the wall, eliminating them from the race. Note: Some racers will take more than one spook to actually hit the wall.

When starting the game and you must choose which car to buy, select the Mazda RX-8 if you want the fastest in stock out of all the other cars. Two other good cars to try at the beginning of the game are the Toyota Corolla GTS and Nissan 200SX.

For League 7 cars, the Infiniti G35, Lexus IS300, and Nissan R32 and R34 are recommended. The Lexus IS300 is good for the Drift Obliterator, Drift King, and Pink Slip races. The Infiniti G35 is good for unlocking performance mods. The Nissan R32 and R34 are good for the circuit and drift racing throughout the game.

Nissans are the best drifters. Try the 500,000 point endurance drift with a Nissan to pass it easier. A Nissan can also be helpful in the League promotion.
