Hint: Daytona: Easy spinouts:
Use Tony Stewart's car and try to qualify in the middle of the pack. At the green flag at the start of the race, take off and cut up on the track slowly. The drivers will usually try to spin each other out.

Hint: Homestead: Drive to infield:
Note: This trick requires the Insane Racer cheat. Go to where you see can RVs. There is an invisible wall. Use Insane Racer to jump and get on the infield. Do not fall into the lakes or you will be returned to the track. To exit, go the same way used to enter.

Hint: Kenyon Raceway: Leave track:
After you pass the start/finish line, instead of turning drive straight for the upper right part of the wall. You then should be able to drive past the parked cars and trailers, and exit the other side back out on the race track.

Hint: Mankato Raceway: Drive to infield:
Select the modified cars and go to Mankato raceway. Go into the pits and there will be an opening in the wall. Go into the opening and you should be in the infield.

When you chose a series, chose "Modified". Drive to the backstretch all the way. When you see the concrete, stop in front of it and turn around. Forward, you will see two regular walls. Drive between them and stay on the accelerator. You should be in a different part of the infield.

Hint: Gain places easily:
To gain a lot of places at the start of a race, turn backwards and keep crashing. The more damage you do to the other cars, and the more critical the damage, the more likely you will gain places.

Hint: Big crashes:
Go to the Modifies and choose a car and track. At any time, go backwards and hit the field of cars. If you hit them correctly, directly on the front tires, you will see the front tires of the other cars go flying into the air. This works with all the other classes but modifies work the best.

Unlock the "Horn Ball" cheat, then go backwards, preferably at Talladega. Immediately before you reach the pack of cars, shoot a horn ball. The ball will go through the first car and will hit the pack of cars behind it, causing a massive pileup.

At the Cup series, go to Talledega with the stability control turned off. Start the race and allow a car to your left to spin you out on the backstretch. Wait until you are at least at 180mph to do this. When you are completely backwards, hit the brakes and your car should start lifting off the ground. This may require more than one attempt.

Glitch: Pit crew over the wall:
When in the practice pit and the crew members jump over the wall, restart. They will still be there when the game resumes.
Chris.

Glitch: See other tracks:
Unlock and turn on the "AI Vengeance" option. Turn around at any track in the cup series. Hit a car and you might go very high in the air and then see other tracks. Note: Most of the time it will place you back on the ground.
