Note this sequence of pictures huge object in the form of spring to handle Felipe Massa

It is incredibly large the spring has more than one inch compared to the use of mass ... is enormous and must be heavy .. now I do not understand is how a piece of track was jumping in the car after it's release .. Brawn Barrichelo it was far from the camera so that mass is not the car ... Brawn of this spring is that it was jumping on the track without stopping ...
