Check out this video of a 4-tire change during a Ferrari F1 pit stop. Don't blink!

Ferrari F1 Pit Stop

 

Wow hyper quick.

 

Amateurs.
I can change all four wheels on my roadster using the screw-up jack faster than that ! NOT !

 

And to think, it's just another day in the office to them.

 

With 21 guys in the picture, they better be able to do it fast...

 

Reminds me of a few years ago when teaching my older son how to mount wheels on a car. We were removing the summer wheels off Mom's car and mounting the winter wheels which we had done in previous years. With little supervision this time, I overlooked the fact that my son forgot to torque one of the wheels. The bolts were just hand tightened. The next day my wife went out driving and complained of noise and a vibration coming from one of the wheels. Without waiting, she immediately went to the local garage where the mechanic said to her "your wheels weren't tightened". At no charge, he torqued the loose wheel.
She never looked at me the same afterwards!
We are now two years divorced.
