No restricter plates at Talladega
Note: This cheat involves editing a game file so make a backup copy of the file before going on. Then use a text editor to edit the "taladega.txt" file in the "tracks/taladega/" folder in the game directory. Find the line that starts with "SPDWY" and change the first number from "1" to "0". Now speeds above 230 miles an hour can be achieved.

Hints & Tips

Easy win
To win easier, turn off damage and put the laps and the cars down. You can now race backwards and take out the other cars. Then finish the race.

Odd number
Simply create a new car or repaint an old one. If you make it's number "00", it will list the car's number as #100.

Competitive races
Note: This cheat involves editing a game file so make a backup copy of the file before going on. Then use this trick if you ared tired of having to change the opposition strength at the race menu each time you race at a different track. First, set the OPPS within the game to 100%. For example, if you are racing at Atlanta, go to the Atlanta track folder and make copies of the "atlanta.txt" and "records.txt" files in the same directory. Then open the "atlanta.txt" file, then scroll down the arcane capital letter words such as "TNAME", "SPEEDW", "LENGT". There are only a few lines that you can change without you crashing the game.

LAPS: How many laps are in a full length race.

QUAL: How many qualifying laps there are. Do not change the first number. There should be two. The first number is only a place-holder.

BLAP: The average qualifying time for the computer cars, x 1000. For example, if the time is 23.456 seconds, it will appear here as 23456. Find your average qualification time and enter this here to qualify close to the middle of the pack.

RELS: Same as opposition strength. If you have both RELS and OPPS at 97%, the cars would travel at 97% of 97% (or 94%) at that track.

Create your own seasons
Note: This cheat involves editing a game file so make a backup copy of the file before going on. You can also create your own seasons by editing the ones within by the game. These will be in the main folder called "nascar3". Search for a file called "nascar.cal". Open it in a text editor. You will see five numbers for each track, for example: 1 3 7 0 0. The first number is the race number. In the example, this would be the first race of the season. The second number is the month of the race. The third number is the day of the race. The meaning of the fourth number is not known. The fifth number is a "0" for a day race or "1" for a night race. After the number will be the name of the track in capital letters. Then, the event name appears twice, followed by how many laps you will race. Whatever the laps is defined here overrides what is in the .txt file for any track. Then there will be the two image files used for track information when  you start a race.

Edit files
Note: This cheat involves editing a game file so make a backup copy of the file before going on. Go into a track folder. There will be a text file for each track in the format "trackname.txt". Now open it with a text editor. Search for the line that reads "CARS". Change both numbers to 44. This will give you 43 cars, which is the maximum for that track. You can now have 43 cars at each track. Also, if their are two pits on the track there will also be a "PIT" and "PIT2" entry. Look at them and you will see a single double digit number. Change these both to 22. This will even out the pits for the track. If not, all the extra cars will pit on the back pit.
