NASCAR 4 Cheats

Win easily at Bristol:
Set your car to the highest air pressure in the tires and lower the spoiler as low as possible. Take all the grille tape off and set the weather temperature as low as it possible so your car will not overheat very fast. Turn cautions on so you can give your engine a cool down. In the corners, run right on the wall and turn as sharp as you can. On the straightaways run near the top of the track. Finally, remember to keep the pedal to the metal.

Win easily in season mode:
In season mode, set the number of cars to "1", and you only have to beat that car (usually Steve Park's #1 car).

Get into first:
At superspeedways, if your car does not go fast, slow down and let the leader catch up to you, then crash into him. They may retire, so you can lap them.

Extra slow cars:
Go to "Driver Info", modify original, then select the driver that you want to drive slower. Go to "Rating" and set everything to 0. This can be done separately to each car.

Custom car appearance:
Select the "Opponent Manager" option on the main menu. Click on the name of the car that you like, then go to the paint shop. Click on "Export" and enter a filename for the car decals. Go to the decals for the pit people, click "Export", and enter a different filename. Save, go to your car's paint shop, and click "Import". Find the filename entered for the car decals, click it, then select "OK". Then, go to the pit people and do the pit decals. Do a little work to change the number to your own and your car will have a customized appearance.

Remove Restrictor plates at SuperSpeedways:
Using your text editor to edit the "track.ini" file in the Daytona and Talladega folders in the "\nascar racing 4\tracks" folder. Find the line "chassis_type = 1" and change it to "chassis_type = 2". You can npw reach speeds of over 200 mph on these tracks.
