"As part of this, we have implemented procedural adjustments to ensure that front bib clearance cannot be easily modified. In some cases, this may involve the application of a seal to provide further assurance of compliance."

This news comes at a bad time for Red Bull, who are under pressure to turn up in style at the United States GP as they await the outcome of their final major upgrade package of the year.

The reigning world champions have all but conceded the Constructors' Championship title with McLaren streaking 41 points clear after back-to-back Grand Prix victories, while Max Verstappen is under pressure from Lando Norris in the Drivers' Championship.

Despite the current momentum, Helmut Marko believes Verstappen will come out on top. "Because he is the best mentally and as a driver," he said earlier this week. "Norris is weak at the start, and he's not the strongest mentally.

"The pressure increases with every race because in reality, he has to win every time to catch up. Max finds it easier to defend. And with Austin and a week later in Mexico, there are now two circuits that suit him really well."
