an undesirable condition of the race car. This is when the car's set up causes the back end of the car to overtake the front end while entering or exiting a turn. NASCAR teams are experts in adjusting the race car quickly during pit stops to make the car tighter or looser depending on the condition of the car. Some cars will get looser as the longer they run without new tires or as the track heats up or cools down.
