Use Of NOS:
If you install a NOS system on your car, you can tap into it by pressing the R1
button. The Nitro guage is located to the right of the dash. Once it is empty, you
will need to take a pit stop to refuel it or wait for it to slowly recharge.

Hidden Controls:
There are a number of "hidden" controls in Gran Turismo 4 that will make
navigating the game a bit easier.

On the main Gran Turismo Mode screen, press L1 to jump the cursor to Home,
and press R1 to jump the cursor to the country of your vehicle's manufacturer.

When looking at your garage in Home, press START to bring up the vehicle
settings screen.

When changing your vehicle's settings, press START to enlarge the Engine
Power/Torque curve.

At the end of a series race, press START to skip the finish times and championship
points screens.

During a replay, press L3 to fast-forward.

During a pit stop, press X to to stop refueling, letting you get out of the stop
faster.

With the Driving Force Pro wheel, press any combination of the LEFT, RIGHT, and
DOWN buttons on the D-pad to look in that direction while driving.

Transfer Files:
If you have a save file from GT3 you can import money and licenses into GT4.
You can transfer license qualifications but you do not receive the unlockable items
that come with the license when you get them without importing. You can transfer
money up to 100,000 dollars. This can only be done once.

Best Starting Car:
To smoke the competition at the beginning of the game purchase the Mitsubishi
Lancer Evolution GSR '92, on sale in the Used Car Showroom I.

Horse Power:
When you buy or receive a new car, before driving it change the oil. This will
increase the Horse Power of the car, which sometimes can be a pretty significant
increase.

Repeat Racing:
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.

New cars and tracks:
To unlock cars and tracks, compete in the GT Career mode. You can earn money
there to upgrade your cars, and buy or sell new and used ones.

At the places where you can buy your cars (for example, BMW), you can find
races that use a certain model of that dealer. This will unlock some of the bonus
cars you cannot normally buy or win in a race. The cars that you get are very
fast, and you can sell them for a decent price.

You can win different cars from series races that you have already completed. For
some series, you are given the option if you would like to clear your current
records. If you do this, you can race those courses over again to win another
prize car.

Special rims:
The "Today's Special Rims" rotate every thirty game days. There are thirty
different sets of rims. There are 439 total "Today's Special Rims". If you see a set
you like, you will only see them every thirty game days -- buy them while you can.

A-Spec Points:
If you enter a race, and all the cars are very low end and you have a high end
car, you will get very minimal A-Spec Points awarded and vice versa. For
example, enter a 800 hp car into a race with the other five cars having between
200 hp to 300 hp. You will probably be awarded only 1 A-Spec Point if you win the
race. Conversely, if you enter a 800 hp car in a race with five other cars that have
between 750 hp to 900 hp, you will be awarded anywhere between 50 to 100 A-
Spec Points.

To get the most A-Spec points out of a race and still have an advantage over the
rest of the field you are up against, do the following to your car. Equip the
following: nitrous bottle, any type of transmission, any clutch, any flywheel, any
limited slip configuration, the carbon driveshaft, racing brakes, the brake
controller, any suspension configuration, the VCD controller, the increase rigidity
option, and the rigidity refresher plan. You can also configure the "Auto" setting on
the "Transmission" option under "Setting" without losing A-Spec points. Note: Do
not do any weight reductions. This will cost you A-Spec points for every race and
is irreversible. For example, if you start a race that is worth 108 A-Spec points,
doing a Stage 1 Weight Reduction will cost you about 17 to 20 A-Spec points,
bringing the total down to 88 to 91, and so on for Stages 2 and 3. If you have
already done a weight reduction to the car that you are in, you can lower the
quality of the tires currently equipped to bring the total back up to the race's
original amount and/or more. However, lowering the tire quality greatly reduces
the chances for success. For example, if you have S2 Tires equipped with a Stage
1 Weight Reduction and only get 84 A-Spec points for the race, try to drop the tire
quality down to maybe a S1 or N3 tire to get more A-spec points for that race.

Easy Nurburgring 24 Hour Endurance Race win:
Obtain the 2004 Ford GT LM Race Car Spec II (the white and black car in the
opening sequence) from the Professional Events-GT World Champion race (ten
races totaling 136 laps on ten different tracks). Buy everything available for the
car, most importantly the Super Hard Racing Tires (R1s). Set the Auto
Transmission feature to a value of 18. Equip the R1 tires and get ready for at least
twelve hours (of sped up time) of hell. You must do this race in B-Spec mode with
the 2004 Ford GT LM Race Car Spec II in order to guarantee a long hard fought
win within thirteen hours real time instead of twenty four hours real time. In B-
Spec mode, you have the option to speed up the race by entering the Race
Monitor Screen by pressing R1. Then, hold L1 and use the D-pad Left or D-pad
Right to go from real time up to three times normal speed. At the beginning of the
race, set the auto pilot to a value of 5 (Push) and turn the overtake feature on by
pressing Triangle. Once you get ahead of the pack and have a decent lead, turn
off overtake and set the autopilot to 2 (Cruise). You should only have to pit every
three to four laps. Get everything every time that you pit (tires and fuel). Set the
autopilot back to 2 (Cruise) once you leave the pit. Continue this strategy until the
end of the race. This will net you a Formula One car.

View ending sequence:
Win The Gran Turismo World Championship in Professional Events.

Secret Black Cars:
The vehicle line-up in the used car showrooms is constantly changing. On the last
week of the changing cycle--starting day 694--four secret black race cars appear
in the showrooms. Two of the cars are in the Used Car Showroom I and the other
two are in Showroom II, and they only appear for one week (Gran Turismo time).
All four cars can be purchased for about Cr.8,500,000 total, which is an absolute
bargain for these sort of race cars.

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!

Press To Pause:
At any screen with scrolling text, pause the ticker by pressing L3. The information
ticker sometimes have the best tips in the game.

Audi Nuvolari Quattro:
Notice that after you have completed 25% of the game, you will reveive a new
car, like if you've just finished a tournament. That car is the Audi Nuvolari Quattro.
