Pit Stop Choreography

• American Le Mans Series racing tires typically weigh approximately 20-25 pounds each.

• The fuel capacity of Series cars varies among fuel types and classes. Diesel-powered LMP1s can hold a maximum of 81 liters. All P1 cars powered by E10 have a maximum capacity of 90 liters (as do GT1 and GT2 cars) while cellulosic E85-powered cars hold up to 110 liters. LMP2 cars can have a maximum of 80 liters.

• Four tires are changed in six to 10 seconds.

• Racing fuel is added in 20-25 seconds.

• Two pit stops are typically made during the Series’ sprint endurance format races (2:45). In longer Series races such as the 12 Hours of Sebring, race cars will usually pit about every 55-65 minutes.

• Maximum pit lane speed during a Series race is 60 kph (37.3 mph).

• A pit crew supervisor is permitted over the pit wall just prior to a scheduled pit stop to signal and stop the race car in the pit box.

• The pit crew supervisor may talk to the driver or pit crew members during a pit stop but is not allowed to perform any other function.

• Aside from the pit crew supervisor, all other team members and equipment must remain behind the pit wall until the race car has come to a stop in its designated pit.

• All pit crew members must wear full fire suits and safety clothing.

• After the race car has come to a complete stop, up to four (4) pit crew members are allowed over the pit wall to service the car.

• The only way a driver (entering or leaving the race car) can service or perform any work on the race car during a pit stop is if he/she is considered one of the four servicing pit crew members.

• A single crew member who mans the fire extinguisher also is allowed over the wall.

• Outside of the team, specific industry representatives who are examining car equipment such as tires and/or other components are allowed over the wall during a pit stop.

• Only the driver is allowed to restart the car before it leaves the pit box.
