It begs the question, how is that area of the car normally adjusted?
There are numerous adjustments that can be made to a car with the turn of a spanner, key or other such tools.
Clearly this "device" is different to a straight forward method of adjustment.
If you take a wing for example, it's a twist or two of an Alan Key and jobs a good 'un. So surely the bib area under the car would have a similar simple method of applying adjustment? Following that logic we then have to ask, why go to all the effort to design a device to make what would on the face of it be a relatively straightforward adjustment and, one that can apparently only be done when the car is stripped down in some way to allow access to it?
No doubt one of the F1 Experts in the media or Ted Kravitz, will have more information on precisely what this device was
