1 // Dirk Werner, driver
"When our chief strategist Jay O'Connell radios to say 'Pit this lap', I head into the pit lane with my BMW M6 GTLM. At the entrance of the pit lane, I hit the speed limitation device on the steering wheel since the speed limit here is 80 km/h. If I drive too fast, I will receive a penalty and I don't want to risk that. I keep a lookout for Jim Volini, who uses a lollipop - a round sign on the end of a long pole - to mark the exact spot at which I need to stop the front of the car. And after that I have to stay focussed. As soon as I am back on the ground, I start the engine, release the clutch and drive off in first gear and with the limiter pressed. I don't go at full throttle again until the end of the pit lane."
2 // Jimmy, Fahrzeugchef, front wheel change
"We are under enormous pressure during a pit stop. We know how much depends on us, and that every second counts. But we have to remain focussed and can't make any mistakes. You need nerves of steel. Before Dirk is told to stop via radio, the entire crew is at the pit wall and ready to spring into action. As soon as the car is there, everyone jumps over the wall and I run into position. The outside wheels are changed first. I use the impact wrench to remove the wheel nut and take off the used tyre. Marty picks it up. Then I fit the new tyre. Now I sprint to the front left wheel to change that one. Then I make sure that the rear tyres have also been changed. In the second that Mike removes the hose from the tank, I give Dirk the signal to drive off."
3 // Mike, refuelling
"When the car turns into the pit lane, I am already sitting on the wall holding onto the fuel hose and the valve. I have already vented the system. If there is any air in the hose, the fuel isn't pumped into the tank at the right pressure and the stop takes longer than planned. How much fuel we put in depends on the race. On average it is about 100 litres of fuel. You never know exactly how the car is going to come in. However, the drivers usually stop in exactly the right spot, which is very important for me since I am moving around with the heavy can and need to find the tank opening exactly. When the car is in front of me, I push the valve onto the tank. Refuelling is what takes the most time during the pit stop. So as soon as I remove the hose from the tank, the car can return to the track."
