The complete guide to performing 17 second pit stops from every crew members responsibility

Imagine you're a pit-crew member for a NASCAR Winston Cup Series team. Your team's driver is making his way through the field, but he needs to pull into pit road for service.

Now it's time to jump into action -- change four tires, refuel and make small adjustments. All this work must take place in about 20 seconds. Spending too much time in the pits can cost a team very valuable track position. With that pressure in mind, pit crews do whatever they can to accomplish their job quickly and get their driver back on the track before anyone else.

An "over the wall" pit crew is made up of the gas-can man, the catch-can man, the rear-tire carrier, the rear-tire changer, the jack man, the front-tire changer and the front-tire carrier. Each member, with headset on and equipment in hand, finds his spot on the wall, which separates them from pit road, and gets ready to do their job.
