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.
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.
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.
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.
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.
