The fastest car is the Supra RZ. Be careful though, because it is a FR car and easily spins out.
Information in this section was contributed by AGuyNamedBob.

The car with the most power when fully tuned is the Nissan Skyline R33 GT-R. With every single upgrade enabled, the car will have 955 HP. If you change the gear ratios, the car will go at speeds in excess of 600 mph -- however, there is no track long enough or strait enough in the game to reach that speed.
Information in this section was contributed by Seb Puglisi and Kyle Church.

The purple Concept Car is the fastest car in the game. When properly tuned, it will beat any car in the game, including the GTO Twin Turbo and Skylines, by a good ten seconds in a three lap race.
Information in this section was contributed by PDRacine.

If you have a 4WD or RWD car with at least 700 horsepower and it has the Full Racing Transmission, you can set individual gear ratios to make it faster. First, set the final gear to level 35 on a Supra (for example). Set each gear down three sets (for example, 0.332 to 329). Go to the Max Speed Test. You will notice your car may be able to top out at anywhere from 200 to 250 mph. Remember, setting the individual gears improves acceleration. Setting the final gear improves top speed.
Information in this section was contributed by MegaMan589.

The fastest car is the Toyota Supra RZ. It only has 910 hp (when fully tuned up). However, it can reach 255 mph. Go to the settings before any race, select the gear ratios and change them as follows: first: 3.214; second: 1.925; third: 1.302; fourth: 1.000; fifth: 0.752; sixth: 0.580; final: 4.011. The Supra should be able to do 255 mph however, it is a FR car. For races such as Mega Speed Cup, the Toyota Supra will definitely be your best choice.

Use the following trick to get the Escudo over 400 kph. First, make sure you have the Turbo Kit stage 4 on the Escudo (1791 hp). Try to get super soft tires, as these decrease skidding. Go into machine test, and on maximum run (full lap). Once done, find the main options before starting the "Settings" option. Then use the following settings: Ride height: Front: 75mm, Rear: 75mm; Gear auto setting: Wide; Final gear: 2.200; Downforce: Front:0.85, Rear 1.80. Note: You must take the corners carefully as the car's speed decreases the more you turn.

Recommended cars:
Some people think that the GTO Twin Turbo is the best overall car but the used R33Skyline '95 GT-R Vspec has better speed, acceleration, and slightly better handling.
Information in this section was contributed by AGuyNamedBob.

Although the Skyline has more horsepower, the best overall car in the game is the used 1995 Mitsubishi GTO MR. Fully upgraded, it has 930 hp, can reach speeds in excess of 260 mph with a little tuning, and has a better 4WD system than the Skyline.

The best car in the game is the Mitsubishi GTO LM Edition. It has the best handling around turns and of course on straight aways. You can also go into turns very fast if you know what you are doing, using the brakes to help. Then you can accelerate out of a turn very fast. The top speed is also great.
Information in this section was contributed by Zst13.

The best car in the game is the Mitsubishi Galant (the most expensive version), if you tune it up to the maximum. With everything, it goes about 220 mph and has the best handling.
Information in this section was contributed by max.

The best car is the GTO Twin Turbo, when it is tuned up to the max. It can reach 930 hp and travels at a maximum speed of 405 km/h. This will set you back a bit, as it costs 43,000 credits and you have to buy all four turbo kits. You can buy a used GTO '92 Twin Turbo for 16,000 to 18,000 credits. This will tune up to 928 hp and can still reach the speed of a new GTO fully tuned up.

The best cars in the entire game, if you can drive them correctly, are the Nissan Nismo Skyline Spec model car (500,000 credits) and the Toyota Chaser Lm won in the GT Cup.

Duplicate parts:
Purchase two identical cars. They may be given different color schemes if desired. Buy as many parts as desired for the first car. View the list of fitted parts of the first car from the garage. Switch to the second car, get inside, and view its fitted parts list, which should be empty. While remaining in the second car, enter a spot race. At the qualify options, select "Machine Setting", then "Change Parts". All the parts from the first car should be available. Exit the race and return to the garage. View the list of fitted parts for both cars to see that all desired parts have been duplicated. Note: Only items available on the "Change Parts" menu may be duplicated. This trick will not work on cars that have been awarded.

Memory card battle with only one card:
Enter memory card battle mode. A message will appear stating that player one is loading and that no memory card was found for player two. Wait until the information has loaded for player one, then remove the memory card and insert it into the second memory card slot. The game will load data from that location and allow both players to participate in the memory card battle.

Glitch: Save money:
If you have bought a car and intend to apply "Racing Modification" and "Weight Reduction" stages one through three, perform "Racing Modification" first. Then, go into the "Weight Reduction" menu. If done correctly, when you try to buy any stage it will say "Finished Fittings For Racing Modification".

Glitch: More maneuvering room:
This trick is very helpful when in a tight spot and will work in both arcade and simulation modes. It is most noticeable in straight aways but takes effect anywhere in the course. When in a race and are surrounded by cars with no room to move, if you are on the camera angle where you are not in the car but the view that puts you closest to the car, switch to the view that puts the car farther away. All the cars (including your own) get smaller, however the track stays the same size. This gives you more room to make a move for a turn or to speed up and gain positions.

Glitch: Go through wall:
Note: This was done with the Mitsubishi GTO, fully specced out. Choose SR 11 as a track, and get up enough speed to spin the tires against the wall as soon as possible. Try to fishtail the car against the wall as you crawl along the right-side, as if you were trying to fry the tires off the rims. Constant wheelspin is critical to this trick. On the sixth bend (going to the left prior to the hairpin), there is a right angle in the right-side wall of the track at the end of the guardrail. While patiently maintaining wheelspin at all times (for at least five minutes continuously), try to fishtail your way through the wall at this weak point by steering back and forth with the correct timing. The body does not block you from the walls; the wheels do. Try to work each wheel through the gap. As you fishtail, you will eventually work through the wall one wheel at a time, and slowly penetrate it, eventually breaking through to the "abyss". If you maintained wheelspin long enough, a built-up value in memory (a benign stack overflow) will give you a nitrous boost to accelerate you to the game's speed limit of 655 mph before it fades (do not let off the throttle). This method can be used to penetrate weaknesses in the walls of almost any track on both Gran Turismo and Gran Turismo 2, however the nitrous trick seems to only work for the original Gran Turismo. The wheelspin builds up this "nitrous charge", and nothing else. Causing oversteer to build up helps increase the rate at which this "boost" builds. Try it in an endurance race so you can see how it burns up the tires fastest. After about 565 mph, you start to run in reverse until you "tick-over" again to a forward speed.

Glitch: License A-3:
Do a 360 and come at the back wall going about 100 mph. Ram into the back wall. As soon as you hit the wall you will noot move and go to 0 mph in about 0.2 seconds. Also, hold down the gas and brake at the same time. You will go nowhere but your bumper will jerk up and down as long as you hold it there.
