After losing parts in both practice sessions, Haas boss Guenther Steiner admitted that it wasn’t a good day for the American team at their home Grand Prix weekend.
Both Romain Grosjean and Esteban Gutierrez both lost parts during the two practice sessions, something Steiner said was because of a recurring wing problem.
After the French driver shed some debris on the track during FP2, the session was red flagged until it got removed.
"We didn’t do good [on Friday]," said the team boss.
"We need to do better, we had a few issues with some rear winglets breaking off. We are not there with the speed, we need to work hard to get there for FP3, we need to step it up.
"I don't know, three or four times, but it’s always this winglet, and we realise now why it is and we’ll fix it. We didn’t expect these high loads, and between these loads and the vibration we lost them."
Steiner also added that the high-speed first sector isn't doing them any favours as he outlined it as one of their weak points on their home circuit.
"Kerbs, and the high downforce through the first sector, corners three, four and five, there are high loads with a lot of vibration. We’ve seen it and we'll fix it," he concluded
Grosjean finished FP2 P18 while Gutierrez ended his day P20.
