Boss car warning:-  When considering buying a car, do not buy any of the cars that are used as Boss cars. If you buy one you will end up having two of the same car. Your garage can only hold 20 cars, and there are 24 cars total. The four Boss cars have their own separate garage and do not take up any of the twenty slots. You cannot get 100% completion if you buy any of the cars used as Boss cars.

Music:-  To listen to the music that you have encountered, go to the main menu and select "EA games Pocket Trax". Here are the song that are in movie mode:

The DONOTS: "We got the noise"
Soulwax: "Any Minute Now"

Car selection:-  If you are having trouble figuring out which cars to use for what event, cars with high top speeds/acceleration are good for drag races; cars with good controls/handling are best for drifting; and cars with a balance of the three are good for normal racing.

Nitrous runs:-  On the nitrous run levels, let off the gas through tight turns. Otherwise, you will hit the wall and flip your car.

The boss car the game chooses to race against you depends on the level of the race and the car you are using... so if you aren't racing against the car you want, you need to change the level of the race or the car you are using. You need to defeat the same boss car in multiple different Boss Races in order to unlock that car.

Ride invisible wall  -  While driving, hit a turn too hard to fly up and over the railing. There is an invisible wall that you can ride. If you ride it correctly, you can land back on your wheels.

Drive through doors  -  On the Bayside Run course, there are doors that you can go through without them moving. Drive over 175 mph and have NOS on when you are about to hit the doors. You will disappear and go through it to the other side without moving the wall. When you enter the sidewalk sale area, the right front door does not seem to work but this glitch can be done with all others.
