Professional mode:
Select arcade mode, then highlight the "Hard" selection on the difficulty selection screen. Hold L1 + R1 until it changes to "Professional".

Selecting series awards:
Series awards (i.e., cars) are not purely random. Press X when a silhouetted car has the large black circle flashing under it to cause that car to be selected as the award for winning the series. Timing is crucial, since the large black circle only appears under a car for less than half a second. If you are too slow, the next car to get the large black circle will be selected.

You can get unlimited F1 cars by playing endurance races, as you can win prize cars from those races unlimited times. To select a prize car, press X when the black circle is under the car of your choice.
 

To get the series car of your choice, just race all the races in series mode, not single. Save before the last race. Do not exit the series -- use the save function shown after the race is done. Then, start and quit the last race. If you have enough points from previous races you should still win the series, then continue to where they award the series prize. If you get a car you do not want, just exit the game, go back to the title screen, then load. The game will start from the last race you saved at. Quit the last race then continue onto the series and repeat until you get the desired car.

Hint: Saving money:
Do not waste money on upgrading the first few cars you have in the game. Instead, practice being a better driver. Wait until you win a car with some real potential until you upgrade. For example, start out with a Mazda Miata, but do not upgrade. Use it to win a Mazda RX-7 Effini 3, then upgrade.
 

Hint: Easy money:
Go to Super Speedway in the Beginner League and keep doing the same level for easy money.

Go to the Beginner League and race in NA to get 5,000 credits.
 

If you have a good car, go to the Amateur League and race in NA for 15,000 credits.

If you have a very good car, go to the Amateur League and race in GT All Stars in the test course to get 25,000 credits. Note: Buy the cheapest tires, as they last longer.

Get a fast car and race the Speedway in the Final Series Race in the Beginner League to win 10,000 credits.

In rally mode the first race award is 5000 credits. the second race earns 10,000 credits, and the third race results in 20,000 credits. You will also receive a rally car when you complete all three of the races, which you can sell for at least 75,000 credits. .

Get a good enough car to race and get first place in the American championship. Start the series race and get first on each course while saving in between each race. When you get to Laguna Seca, start the race and then exit. You should have enough points that you will still win the championship. Keep repeating this until the race prize is the Camaro Race Car. Sell the Camaro as soon as possible to get 250,000 credits. In all you will get 30,000 in race prizes, 20,000 in series prizes, and 250,000 for the Camaro -- totaling 300,000 credits.

Win the 150 mile Endurance Race and sell the car you win to get 500,000 credits total. This will take about one hour.

Get either a fully upgraded Dodge Viper (1088 hp) or the Camaro Race Car. Go to the European championship. Win first place in the first four races and then save the game. Skip the last race. If you get the Vertigo Race Car, keep it. Repeat this process and get the Vertigo again. It can be sold for 300,000 credits. Repeat this process as needed.

Hint: Easy money with memory card:
Two memory cards are required for this trick. After you have earned about 200,000 credits, purchase a car, such as the Mitsubishi 3000 GT. Upgrade it up to the max. This will leave you almost broke. Go home and save this car memory slot two, then return to the title screen and load your last game from memory slot one. This will give you your money back, and you can now go home and trade from memory slot two. That car that you just spent all those credits on will only cost you retail price.

Hint: Free tuning with memory card:
Two memory cards are required for this trick. After getting some money or cars to sell, save your game to both cards. Then buy the car you want, tune it, and get all the tires. Save your game to the memory card two. Then, load the game from memory card one, go home, then go to trade. Load the memory card two's garage and buy the car you just tuned. Then, save the game to both cards. You have now bought a fully tuned car for the price of the stock car. Repeat this as many times as needed.

Hint: All four bonus cars with memory card:
Use the following trick to get all four bonus cars and all colors after racing a series only one time. Two memory cards and enough money to buy all the cars at the resale price are required. Save to memory card one at the end of the second-to-last race with enough points to skip the last race. Skip the last race. Press X when the black circle is under the desired car. If you do not get the car you desire, reload card one and try again. Once the desired car is chosen, save to memory card two. Reload card one, skip the last race and choose the desired car. Go to trade without saving in the home menu. Load card two in the trade menu. Buy the previously chosen car, then overwrite and save to card two. Reload card one, skip the last race, choose the next car, then go to trade again. Load card two in trade. Next, buy all previously chosen cars, overwrite, and save to card two again. Repeat until all desired cars and colors have been acquired from only one series.

Hint: More speed with automatic transmissions:
When racing with an automatic transmission, hold R2 and you will get better acceleration. Release when the small red light to change gears flashes or the car will not change gears. 

Hint: Acura Intregra Type R: Easy money:
Buy the Acura Intregra Type R. Upgrade it a bit so that you can compete with the cars in the Type R meeting. Win the series to get a lot of money. The car that you win (Acura RSX Type S) can be sold for 7,500 credits. Note: This car cannot be bought in the game so you may want to keep one.

Hint: Super Speedway 150 Miles (Endurance): Prizes:
Win the Super Speedway 150 Miles prize in Endurance to unlock the Chevrolet Corvette C5R, Tickford Falcon XR8 Race Car, and F090/S.

Hint: Super Speedway 150 Miles (Endurance): Easy win:
The Super Speedway 150 Miles endurance race can be won without being in control or the car. Use a rubber band to hold X (accelerate) and Analog-stick to the Right (slightly). You should use a semi-fast car, but the other drivers will be going into the pit while you will not -- time will be made up in this way. Having the Analog-stick in that direction prevents you from going into the pit and never exiting. This is an easy way to make 200,000 credits. You will win a very expensive car, one of which is the F090, which is one of the best cars in the game.

Hint: Easy race prizes:
For example, the Tuscan Speed 6 series has 5 races in it. Make sure you have enough of points in the lead so you can quit the last race and still defeat the CPU on points. Race the first four races, then save before going into the fifth race. Enter the fifth (last race), then immediately quit. You can claim your prize. In that series the two prizes are the Griffith 500, or Cerbera Speed 12. If you do not get the desired car, just go to main menu, reload and repeat the previous steps Since the reload will take you back to the beginning of the fifth race, you can keep trying until you get the car you want. 

Hint: Recommended tires:
For any normal non-endurance race, select super soft race tires. They do not wear out on the track unless you see a tire meter on your screen. For endurance races, use the cheapest race tires. Though the screen says they have the least traction they will have enough after about two laps to keep you going quickly. Despite being the cheapest, they are in fact race tires and work much better than any street tire. You will benefit more by getting extra laps on a set of cheap tires then getting a few faster laps on the expensive tires, which will need more frequent changes. This will also save money.

Hint: Tuning race cars:
The race cars you win can be tuned to go faster. Always save the game before tuning or buying a car. If you do not like what you get, just reload.

Hint: Tuning drive trains:
When tuning your drive train, make sure that you do not get full customization on your gears. Doing so you lower your ability of maxing out your speed. For example, if you buy a Nissan Skyline V-spec II '99 and tune it up to the maximum with full gear customization, and you race it the top speed all you can get is 160 mph. If you race without full gear customization, the top speed you can get is 231 mph.

To get the most speed out of your car you have to get the most horses, however sometimes the transmission will keep you from getting to use all of it. Buy the Full Customization transmission. Now go to the settings either right before a race or at home. Change the settings of the last part of your transmission (the bar that has Sports on the left and Wide on the right) to all the way left. This will move your individual gear ratios. Next, go to the "Final" bar and move it as far right as it will go. Then, go to the next bar up and move it as far left as it will go. Do that to the remaining bars. When racing you will notice that your gears will shift extremely quickly, however, the bad starts will lead to every single horsepower being used. This is really only needed in high-powered cars that exceed 650 horses and should not be used in short races with competitors having equal power to your own.

Hint: Avoid going airborne:
If you buy the Toyota Supra, Nissan Skyline, or any other car that has the capability of having around 1000 hp, do not remove any weight besides stage one. If you decide to remove weight, do not race the rally races with them, since they tend to get airborne.

Hint: Better cornering control:
Tap the emergency brake (default is Circle) just before a sharp turn and let the car go into a sort of neutral gear state. This will keep the tires from spinning due to downshifting. Using the momentum of the car and a little braking, you should make it through a tight turn without getting turned around or fishtailing most of the time. This is especially helpful on the Laguna Seca Track in the "corkscrew" turns. This turning technique is also helpful sometimes in a rally race. It can usually induce a slide for tight cornering.

Hint: Easy horse power boost:
When you get a car, change the oil. It will boost the horse power by at least 10 and only costs 250 credits.

Hint: Gears and turns:
Next to the current gear the car is in on the HUD, you will occasionally see a red and sometimes flashing number. This number is indicating what gear you should be in when you make the next turn. Sometimes this is overcompensated by how you have set the gear ratios or the condition of the tires at the time, but for the most part, it is a pretty good indication of the speed you need to be at in order to make the next turn without hitting a wall.

Hint: License test lines:
On the license tests, the dotted line indicates coasting, the blue line indicates acceleration, while the red line indicates that you should brake.

Hint: Arcade mode tracks:
To unlock the arcade mode tracks, simply complete each area (A, B, C, D, and E).

Hint: Complex String track:
In arcade mode, in one player mode, complete area D of the tracks to unlock Area E tracks. Then, go into two player mode. You will find the Complex String track all the way at the end. It is the track that you race when you get your license.
.

Glitch: 1300 mph on test course:
Using the GT-1 race car, you can achieve a speed of over 1300 mph on the test course. Make sure your GT-1 race car has all the upgrades, the stage 4 turbo kit, super-soft tires, and a fresh oil change. Next, go into the vehicle settings for the GT-One and make the following changes: Spring rate 4.0 Front/ 4.0 Rear, Ride Height 55 Front/ 55 Rear, Shock Bound/Rebound 1 Front/ 1 Rear, Camber/Toe Angles 0 Front/ 0 Rear, Brake Balance 9 Front/ 9 Rear, Limited-Slip Initial Torque 60, Limited-Slip Accel 60, Limited-Slip Decel 20, Downforce .45 Front/ 1.25 Rear, ASM 10, TCS 5. Here is the important part -- go to the Gear Ratio Settings screen and change the final gear to 5.499. Change the Auto Settings level to 47 and then to level 48. Do not change the settings for the individual gears (i.e., 1st through 6th) -- they should now be set to specific levels. Now, change the final gear back to 3.500, and do not forget to OK the changes. Now go to the Max Speed Test. Make sure to do a 180 (turn completely around) to go the opposite way around the track. Otherwise you will be stopped and given your max speed at the other end of the track. As soon as you come off a corner, the front end of the GT-One should lift up and you will start to go very fast. It is possible to set a max speed record of 1335.3 mph.

Alternately, use the following settings with the Toyota GT-1 Race Car (TSO20) to get over 1250 mph on the max speed test. Use a manual transmission for best results. Spring rate Front- 0%, Rear- 0%,Ride height F- 0%, R- 0%, Shock bound F 7, R 7, Shock rebound F- 7, R- 7, Camber 0, Toe 0, Stabilizers 0%, Limited Slip initial torque F 0, R 5, Limited Slip Acceleration F 0, R 5, Limited Slip Deceleration F 0, R 5, Gears 1st- 2.572, 2nd- 1.613, 3rd- 1.125, 4th- 0.829, 5th- 0.646, 6th- 0.489, Final- 3.964, Downforce Front- 0%, Downforce- Rear- 100%, ASM 0, TCS 0.
