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.
Shoot smoke from nitrous
To make nitrous shoot out smoke, put your car in neutral, or at the beginning of the race press Nitrous.
1988 Nissan Skyline GTR34
Select underground mode and complete at least the first 80 missions. A recommended car to use is the Acura RSX. You will then challenge Samantha. Defeat her under the medium difficulty setting and win the next drag race to unlock the 1998 Nissan Skyline GTR34.
Eddie's: Nissan Skyline
To unlock Eddie's car in the end, keep winning style points. Note: It is faster to win them in drift. When your style meter maxes out, a message stating that you have won Eddie's Nissan Skyline will appear.
Easier drag wins
To get to higher gears quicker in drag races, tap L repeatedly as needed to increase the RPM to the appropriate level to switch the gear. This also lessens the full force of the nitrous to lower the chance of burning the engine out.
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.
Go to quick race mode and choose any circuit. Set it to five laps with maximum cars on. Then, just get near misses in a row to get a large amount of points. Once your reputation goes up you can make 20,000 points in one go around.
Press Nitrous at the start of a race to purge your nitrous for 150 style points.
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.
