Drivers in NASCAR's top series receive all the adulation for wins and top finishes, but without the carefully choreographed dance of the pit crew being executed with precision, there is no glory.
There must be chemistry between the driver and crew chief, but also a solid working relationship with members of the crews who service that car on pit road.
Pit crews are no longer a team of people that work on cars during the week at the shops, and assemble to jump over the pit road wall on raceday.
The pit crews of today are highly trained athletes, some of which have come from professional sports, who spend many hours each week under the guidance of their coaches.
In addition to their athleticism, they must be skilled in not only the routine pit stop duties of fueling, jacking the car and tire changing, but able to repair many of the things that can go awry during a race.
Pit crew members must be trained to execute their specific duties at optimal speed during the 13 seconds or so a car is on pit road. They spend long hours rehearsing those tasks.
This slideshow will highlight the top pit crews in the NASCAR Sprint Cup Series. They are listed based on overall performance in 2012 with an outlook for the upcoming season.
