On Friday evening, the E21 is transported to the FIA garage to the usual monitoring techniques, but here is the unexpected around the corner. At the back of the car there are three holes, in which are inserted buffers that are used to lift the car on the bridge and allow technicians to carry out the changes.
It 's just there that the team realizes the error: the arms had been lengthened, according to the regulation, but the holes were left in the original position and have not been able to raise the car regularly. The machine was, therefore, considered to be " illegal "because uncontrollable, not because he really was.
if i understand this correctly (from google translate), the problem was something like this.
- when the wheel base was lengthened by 10 cms, the t-tray wasn't re positioned accordingly, also
- the mountings or holes where the jacks goes under the floor weren't changed either. thus,
- when the team jacked the car up at the weigh bridge for scrutineering, they couldn't raise it sufficiently/raise it at all as the t-tray got in the way as it wasn't positioned correctly.
this violated the regulation somehow and the car wasn't allowed.
