Easy Drift Points
Simply stay behind a car and watch the points rack up.
Easy Style Points
After you unlock the oval drift track, go into 'Quick Race' and choose that track. Then, race around it using the handbrake to powerslide into the corners. Depending on how good you are, you will unlock rewards every time you fill your meter, which does not take too long.
Use Rims That Normally Will Not Fit
Certain cars can only fit so big of a rim. For example, the Miata can only fit 17s, but if you get a car like the Skyline put 20s on it and trade it in for the Miata. The Miata will now have the 20s that the Skyline had in it. Do not try to install any other rims on your new car because the rims will go back to the maximum sized allowed.
Shoot Smoke From Nitrous
To make nitrous shoot out smoke, put your car in neutral, or at the beginning of the race press Nitrous.
Look for alternate routes on your in-game map while driving. These can get you ahead of an opponent easily or shave off seconds on your timer. They will look like another road on the map, but sometimes are narrower. Most of the time these shortcuts will be hard to see or take, and can be extremely risky.
Get a lot of points in Drift Mode
Get a Miata and rice it whatever way you want. Take it to Drift Mode. Play any drift track with the Miata. The reason is that the Miata is really loose on the oiled course. I don't know why, but it sure looks good if you can control it.
At the main menu, press down, down, left, right, Y, X, right, left.
Go to free run with any car. At the start of the track, hold L and press R. Your tires should be smoking. To stop, just release L.
Extra Style Points in Drift competition
During any Drift competition, pause the game at the moment you impact a wall. Unpause the game and you'll be rewarded with free style points.
Get Dual GT and Katana Spoilers
Win race 77 (Samantha's big tease) and choose the 'Katana' spoiler, then trade in your car for a 'Peugeot 206' then trade back. You now have another choice of spoiler the 'Dual GT' but you'll still find the 'Katana' at the end of the spoilers menu.
While in the Main Menu Screen, enter code.

Have both the Katana and Dual GT Spoiler
Play through the game normally, and once you beat Samantha's Big Tease (#77), pick the Katana Unique Spoiler. Now, to get the Dual GT, trade in your car for a Peugot 206. Then, trade your car back to what you had and now your car has Dual GT as the spoiler. To switch back for the Katana Spoiler, just go to spoilers and scroll all the way to the end, and there's the Katana spoiler! Once you do this, you now will have both Katana and Dual GT in the customize ride from the main menu.
