Faster nitrous refill:
When you drive over 200 mph, the nitrous will fill up twice as fast.

Avoiding cops:
When being chased by the cops, watch out for reckless driving and try to take all shortcuts.

Recommended car tuning:
When performance tuning your car, try to raise "Top Speed", "Acceleration", and "Handling" at the same time, and keep them even as much as possible.

Turn:
When turning a sharp corner and you feel that you are going to hit the wall, turn on the 'speed-breaker' triangle/ down. This will give you an extra 90 degree's of turn.

Recommended car:
Get the Gallardo as soon as possible and upgrade all of its performance upgrades. Everything will be almost full. Try to get the handling better than the speed or it will have no effect. You should now be able to win all events and defeat the Bosses easily.
