NASCAR Thunder 2003 Codes -

Tiburon Speedway track:
Use a memory card with a saved file from an EA Sports 2003 game.

Thunder Plates:
Select the Thunder Challenge or Lightning Challenge at the game mode screen. Complete the various challenges to get new Thunder Plates. Note: The Plates are awarded randomly from game to game -- winning a certain track with a particular driver will not unlock the same Plate between games.

Hint: Easy win:
Make sure all races are set on ten percent race length. Drive into the grass and spin out on lap four, rather than crash. This way, your car is not damaged and you are better able to draft. It also works on lap 7 of all 26 lap races under the 10 percent setting, and on lap 12 or 13 of 39 to 40 lap races.

Hint: Daytona: Easy win:
Make sure the race is set on ten percent race length. Then, cause a crash on lap four. If done correctly, there should be a caution. Go into the pits, and ignore that fact if no one else also enters. You will probably be last, but there will soon be another caution and the leaders will come in. Stay out and do not pit. After the stop, you should be in first or second place. You will run low on gas, but you will not run out. Block and you will be able to win.
