                Getting three Unique Spoiler at same time
                You must have a non-hatchback car available for this cool glitch. First get a non-hatchback car, go to race 77( Time Trial, Samantha's Big Tease ), beat the race to get to reward screen. DO NOT choose Dual GT and Duotek, as they have both saloon and hatchback version and thus won't get you additional spoiler. Instead choose Katana( always ), save the game and exit Underground mode. At Main Menu go check ''customize your ride'' section, choose a hatchback and see Dual GT WILL BE AVAILABLE! Now choose a saloon car you will see not only Katana is available, but saloon version of Dual GT WILL BE AVAILABLE, TOO! 
This will happen almost everytime, but if you have extra cash and want to make sure it happens 100%, choose Katana at Underground mode, go to customize car section in Underground mode, trade-in for a hatchback, and trade back the saloon car again, you will see this happening!! 
As result, you will see only two kinds of unique spoilers in Underground mode( Katana for saloon and Dual GT for hatchbacks ), but at Main Menu you can find THREE kinds of unique spoiler available( Katana & Dual GT for saloon and Dual GT for hatchbacks ). 
Note: due to the glitch, non-hatchback version of Dual GT will stay with your ride's color.
             
                        
                Helpfull Turn Control Hint
                If you have the Automatic Slide Control Turned on (you should automatically have it when you start the game)here's a helpful hint. If you start to slide, your natural reaction would be to turn the opposite way to get the car under control; DON'T! Instead just let the car do the work for you because the auto slide control automatically turns the car so it goes straight, you just have to make sure it doesn't go straight into a wall.

                Money Mayhem
                Play through Underground Mode as you would usually do, unlocking a good amount of cars and performance parts. This is just your initial investment (or 'seed money') for the trick. Save the game. Then buy and modify the VW Golf to the maximum and trade it in for the Honda S2000 for a gain of about $1500. Take the Honda to the garage and demodify it (strip the parts) and trade the Honda for a Skyline (and a loss of about $3000). With the Skyline, you can now trade for the VW Golf for a gain of about $10,000. You can repeat this car laundering until you have enough cash for your dream machine.

                Shortcuts
                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.

                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.
