Double Turn 9 exit kerb installed at COTA
19 October 2017 – Officials at the Circuit of the America have installed a double kerb at the exit of Turn 9, as part of minor revisions ahead of this weekend's United States Grand Prix.
In the pre-event notes, the FIA confirmed that a double kerb has been installed "through the addition of a 50mm negative section behind the existing kerb".
There have also been moves to restrict drivers from taking liberties with the track limits leading onto the main straights at the venue.
Three additional bumps have been installed downstream of the existing bumps on the exit of Turns 11 and 20, the corners which lead onto the back and pit straight respectively.
In addition, extra TecPro barriers have been fitted to parts of the barriers at Turns 1, 4, 6, 12 and 19.
