A frustrated Toto Wolff wants the FIA to react and fix the kerbs after what several incidents in FP3 and Qualifying today.
In fact, Red Bull Ring has displayed some serious flaws concerning the structure of the kerbs, which have already damaged Rosberg, Verstappen, Perez and Kvyat's suspensions, causing crashes or premature stoppages.
"I don't know what the FIA is going to decide," said Wolff. "Whether they are going to take those sausage kerbs away, or whether they are going to modify some of the red kerbs, scratch them, or fill them with concrete.
"I don't know. But we have seen a couple of failures on various cars with the various suspension design, and it still failed, I think there needs to be a reaction .There is some discussion happening. We discussed it during the session that we need to react quickly, with Charlie, and trigger some reaction. But that is not an easy one."
Nico Rosberg's failure during FP3 happened on the red kerbs at the end of the track, and not on the yellow sausage kerbs which are further off line, which is worrying Wolff even more.
"It is a concern. The strange thing is at the beginning it seemed we had spikes of loads. But once we analysed the data there was not much load on the suspension.
"So it is some kind of strange frequency or oscillation on the tyre that makes the suspension break. And we don't know what it is. It looks like it's the red kerbs, which are new, which triggers that."
The remedy arranged to avoid this kind of issues consisted in strengthening the suspension with extra carbon layers, as Wolff documented but such precaution may not be feasible according to the rules.
"We strengthened the suspension. Whether it's the ultimate cure, I doubt it. I think with the parc ferme rules we are probably on the better side because we strengthened them already."
However, Nico Rosberg expressed his multiple doubts over the kerbs. The German also described the unusual and alarming vibration he felt while passing on them, sensation shared by Daniil Kvyat who crashed during Q1.
"The yellow kerbs, you're not supposed to go there, that's one thing," declared Rosberg. "People who do, break the car, that's for sure. But what would the alternative be? I don't know.
"The bad one was my incident, because I was in the really normal, shallow kerb, the first one, just driving out of the corner, and the thing failed. That's the bigger worry which needs understanding, I think.
"It's a vibration, a very unusual never seen before vibration, which comes when you're on the throttle when you're on that kerb. So that's a worry, because it's not something that we've planned for building the car, so not straightforward. They reinforced our car before qualifying, in those fragile areas."
With a number of drivers losing front winglets while passing through these critical zones and widespread concerns for tomorrow, other drivers such as Hamilton and Verstappen have called out the FIA to solve the kerb issue.
But just yesterday, everyone was against Verstappen's critics to the kerbs, who regarded them as “unbelievable”.
