Hamilton was disqualified from second place at last weekend’s race at the Circuit of the Americas after post-race inspections found it had worn more than the 1mm that is allowed in the regulations.
The team was open that it had made an error in running Hamilton too low to the ground, with the bumpy track subsequently causing too much wear.
Reflecting on the error that was made, technical director James Allison has said the squad did not leave enough margin for error after feeling that things were under control after the first and only free practice session.

For its initial analysis of the plank after practice, the only running teams had before committing to set-up due to parc ferme conditions, it showed the plank was not being damaged by the bumps and kerbs.
Speaking in Mercedes’ regular post-race video review, Allison said: “Austin is a track with a very bumpy surface and therefore you are a bit more vulnerable to bumping the car on the ground. We just simply didn’t take enough margin at the end of free practice 1.
“When we had done our set-up, we checked the plank and everything all looked fine, untouched after the FP1 running. But the results of the race speak for themselves.
