On race day, 43 active pit crews participate in the Nascar Sprint Cup Series. The drivers who did not make the race also have their own pit crews.
Everyday.
Safety for both the crews and drivers in the pit.
Yes, pit crews have to be very fast so that the racecar can get back in the race asap.
They can change it in 7seconds
Most of the time the pit crews do a 4 tire change and add a full tank of gas in about 12-14 seconds.
The pit crew does not build engines. The teams engine department does this. The pit crew services the car during a race by fueling, changing tires and fixing the car so it can return to the race if the car gets damaged.
If you are going to a NASCAR mechanic school, it is a good idea to go to some races while working on your degree. You can learn a lot about the industry. However, you should not be watching the cars as much as you are watching the pit crews. You will see how they do their jobs. This can help you to understand your classes and all of the things that you are learning.

Drive down pit road and enter your pit stall.
It depends of the track. Short track like Bristol or Martinsville, the speed limit in 45mph because the pit lane in narrow and the cars are closer to each other.
you have to know a nascar driver or someone that works for them.
