Cheat: Drifting Physics in All Modes
On the main menu, type in: Slidingwithstyle
Hint: Points for 360 in Drift
When you are in drift mode you can get some extra points for doing doughnuts. Hold one direction and the handbrake and gas and let go of the handbrake after a second. You'll just sit there and do doughnuts. This won't get you massive points but it's something.

TTT
Hint: Flip Cars
First "draft" a car until your front bumper touches the opponent's rear bumper, then hit the Nitrous and your opponent's car will be flipped.

Hint: Easy Drag Races
Having a hard time completing a drag race? Strip your car of every performance upgrade except handling and brakes. Your opponents will automatically do the same thing. This makes it easier to make a perfect shift everytime. This will work in all races except the ones that say you have to have a fast car.
