2022 Nike One Morse Code
Look real close on the side of the Nike One, you can see a small area near the front of the car of morse code. If you go into photo mode, this will become clearer. The morse code is written backwards as to be seen correctly from inside the car. Spelled out, it is " Strategic Design Positioning. Tactical Design Implementation. Creative Design Passion.

Best starting car

Cameramen
In the Grand Canyon get to where you see the cameramen trying to dodge you and not get killed. In photo mode, press Select just before or after you pass the cameraman's original standing position, where he runs from the middle of the course. Take a picture, then back out. The man should be standing right where he just ran from, appearing through the car.

Cheating
There are three basic ways to cheat at Gran Turismo 4:

1. Enter a car much more powerful than anything else in the race.

2. Nudge into walls to propel yourself around corners. Note that this requires some practice, and can trigger a 5-second penalty in some game modes (such as driving missions)

3. Under braking, leave your braking late and hit the car in front of you in the braking zone. You will lose speed, bringing you to the correct speed, and sending them off the road! However in some game modes this can also trigger a 5-second penalty.

Credits and licenses
Have a saved game file from Gran Turismo 3 or Gran Turismo 4: Prologue to start with extra credits and some of your previously earned licenses. Use the following steps to transfer your Gran Turismo 3 data to Gran Turismo 4. This must be done when you first start the game. It can not be done after you have already started and saved a game. Put a blank memory card into slot one and start Gran Turismo 4. When the message "Do you wish to create game data" appears, select "OK". When asked to name the save file, enter a name and select "OK". The message "Game data will now be created" will appear. It will then specify how big the save file is (1498 kb) and tell you what slot (slot one) it will be saved to. Select "OK". When the "Save successful" message appears, select "OK". The game will then tell you about its auto save feature. Select "OK". It then tells you about the flashing save icon. Select "OK". The game then tells you about not removing the memory card when the flashing save icon is flashing. Select "OK". Follow the next steps very carefully. The game tells that you can utilize a game save from Gran Turismo 3. It then asks if you would like to see details. Select "OK". You are told that you can transfer credits (up to 100,000). Select "OK". The game then tells you about updating the status of your licenses (A and B licenses). Select "OK". The game now tells you how to load the Gran Turismo 3 data. Read this carefully, then select "OK". You will be asked if you want to start the game. Select "Start". The loading screen appears, then the game brings you back to the main menu. Select "Gran Turismo mode", which is the second option down on the list. An arrow will appear on the "home icon". Press X to enter your home. At the top right of the screen, you will see the word "Status". Move the arrow over to it and press X. Take out the memory card that has the newly created Gran Turismo 4 data and insert the memory card that has your Gran Turismo 3 data stored on it. At the bottom of the status screen you will see (Square) return and (Start) transfer game data. Press Start, first making sure that your Gran Turismo 3 data in now in slot one. You will be asked if you want to transfer game data. Select "OK" Be careful, as you can only do it once. If you make a mistake, you will have to start from the beginning. A message stating that your licenses have been transferred will appear. Select "OK". You will be asked if you want to transfer credits. Select "OK". A message stating that your credits have been transferred will appear. Select "OK". Finally, you will notice in the top right corner that you now have 110,000 credit. Also, to the center left of the screen you will notice the A and B license icons have lit up.

Extra Cash/License Upgrade
Using your GT3 save/GT4 Prologue save, the money and licenses you've earned can be transfered over to GT4 and have half of the licenses completed and have enough cash to buy a car you'd like.

Fast Racing for Fast Profit
Start out with any vehicle you like. When you make enough money to make your vehicle faster using the beginner hall, move over the the special conditions Hall. Defeat the first race (Rally d' Umbria) and you will receive a Cadillac CIEN '02. Get more money and put more power into your Cadillac CIEN '02 (you won't have to if you don't want to). The CIEN will gain almost 1000+ HP. Go to the second race with the CEIN in the Special Conditions Hall called Rally d' Capri. After you win that race you will get a Toyota RSC Rally Raid Car '02 which you can sell for more than $230,000+. Keep racing that race and keep making the money.

To obtain over 260,000 credits easily just take your best car and take it into the Rally d' Capri easy in the Special Conditions hall. Once you obtain the car sell it and you get over 260,000 credits. You can repeat this over and over and soon enough you should be able to afford anything you want.

Enter the European Hall event 1000 Miles! I recommend either the Ginetta G4 '64 (won from Beginner Lightweight K Cup) or the Chevelle SS 454 '70 (won from American Muscle Car Championship). Enter the Cote d'Azur race (I think the last one works just the same). Make sure your car's HP is near or above 200. Put it on B-spec, 5-Push, overtake, 3x speed. Come back after a couple hours (this works best if you leave it overnight). You should have won the race, along with 150,000 credits! This can also be done with the championship race, which is 4 races. 4 races times 150,000 credits plus 300,000 credit prize equals 900,000 credits. The prize car is crappy, but who cares, you have 900,000 credits from doing nothing!

Faster credit reward screen
Hold L2 to load the credits faster. For example, when you win a 45,000 credir reward, holding L2 will make it load much faster. Doing this trick on a 10,000 credit prize will make the numbers disappear completely off the screen in about one second.

Faster replays
During a replay, press L3.

Free Horsepower
When you buy or win a new car, take it for an oil change. After the oil change, your car's horsepower will increase.

Good Start and Lots Of $$
First, do up to the A licence in tests. You should get two cars. Sell both of the cars, buy a Toyota Celica 2000GT-Four from the Historic Showroom, and outfit the car with a small turbo kit, a chip, and anything else you think is nescissary. Go to the special condition events and race the Tsukuba Circuit on easy, you should get the MAZDA RX-8 Concept (Type-I). Take this new car and go to the RX-8 cup in the Mazda dealership. After doing that you'll win the MAZDA RX-8 Concept LM Race Car, in which case you can win almost any race available.

Hidden Black Cars
On days 694-700 in the used car lots you can buy special black versions of:1.Toyota GT One Race Car2.Mazda 787B3.Nissan R390 Race Car4.Nissan R92CP Race Car5.Honda S20006.Clio Sport V6 24V Race CarTo Buy them all it comes to roughly 9,000,000 credits.

Jump directly to car manufacturer
From the main menu (where your garage is located), press L1 or R1 to go directly to the car manufacturer for the car that you are currently in.

King Dome in Seattle Circuit
Just before Safeco Field (The Mariner's Stadium), the King Dome stands on the right. The King Dome was the Mariner's old stadium and was destroyed in a giant implosion on March 26, 2000, and thus should not currently appear in the game.

License test help

Race without the required licenses
If you have obtained all your licenses except for the S License, you can still participate in S License races. Enter the race with the correct requirements for the race in B-Spec mode. You will still earn the prize car and the credits.

Recommended modifications
The first mod that should done to any vehicle is a spoiler kit in the GT Auto department. They cost 1,200 credits and give the greatest value for the money. Choose the ones to the far right, as they have the greatest downforce characteristics. Most cars can get a kit installed. Save money and do not purchase a Stage 3 NA kit and a supercharger, as they cannot be installed at the same time. Also, when going for the turbo upgrades, look for a fifth kit called "Original". This is usually cheaper than Stage 4. If you have the money to get this straight away, it is better to do this first, as it does the job of Stages 1 to 3 combined, and then some. A recommended strategy for a broad spectrum of cars is (in order): spoiler, full custom gearbox, computer chip, full custom suspension, NOS, race exhaust, then start on the engines.

Recommendend game start
Before buying any cars, enter the National B License tests. It will give you valuable information on how to drive and when you get all bronze you will win a VW Lupo which can be entered into quite a few races. You can use the money you save for upgrades instead!

Remain in current gear with automatic transmissions
When racing with an automatic transmission, hold R2 to force the car to remain in the current gear. Release R2 when the small red light to change gears flashes or the car will not change gears. This useful for remaining at a given speed through a corner, or stretching the top end of a gear for a little extra speed or performance.

Speed up B-Spec Races
While in a race in B-Spec mode, press R1 to switch to Race Monitor. Hold L1 + Right on the D-pad and you can make the race go up to 3x's faster. The only downfall is you have to stay on the Race Monitor screen in order to keep the race sped up, it switches back to 1x when you go to Broadcast View mode.

Speed up replays, and turn off BGM
To speed up your replays simply press down L3 and to turn off the background music simply press O.

Start in first place in a race
When you are about to choose wether you want to do the race A-spec or b-spec go left until you get to practice go in race in this until your first then quit the when you start the race you should be in first place. It doesn't mater wether yuo do it a-spec or b-spec.

Stay in same gear in Automatic transmission
When using the automatic transmission option, hold R2 to make your car remain in the same gear. This is great for remaining at a given speed through a corner, or stretching the top end of a gear for a little extra speed/performance.

Stop scrolling text
At any point that you see scrolling text at the bottom of the screen (at the main menu or when buying parts for your vehicle), press L3 to stop the text from scrolling.

Toggle ghost racer
After you finish one, try a B, A, IB, IA, or S license (1-16) or rally. The ghost racer will be on. If it confuses you, press D-pad Up to toggle it off or on.

Tune car while at house
While at your house, hold L1 + L2 + R1 + R2 + Select + Start to go to the car setup/tune page. This saves a lot of time, as you can set your car up for arcade races without first starting a race, then tuning, then going back to the main menu. Additionally, when at the screen where you select to go into the Garage, Status, Diary, etc. and are in the car that you want to tune, simply press Start. You will be sent to the tune car screen.

Unlimited Money
To get unlimited money, buy the Mercedes Bendz SL 65 and enter the Pan Euro Championship in Europe. Do the series race and if you win it you will get a car. That car is worth 300,000+ credits. You can keep doing that over and over and over to keep making the money. you can also do the same exact thing with the last European Championship.
