Guys, the hood levitating was not done on purpose. While Le Mans Classic was our first race with the car, we did not have any problem during testing / qualifying, and the hood stayed in place. But during the race for some reasons, it popped off. It was a shock while driving to see that hood levitating, but after a moment we realized it would not go anywhere, just levivating a bit (and help cooling :-)). So we kept on racing.
