Mixed feelings in paddock as F1 issues porpoising clampdown
The sport's governing body said it consulted with doctors and, "in the interests of safety of the drivers", issued a technical directive that will involve checking the "design" and "observed wear" of the 2022 cars' floors.
Another move will be to set a "quantitative limit" on the amount of allowed bouncing.
"I don't know how the FIA plans to do this," former F1 driver Ralf Schumacher told Sky Deutschland.
"But the formula can't be the same for every car and every aerodynamic approach because one team has solved it better, another team has solved it worse.
One of those complaining drivers, however, is Ralf's own nephew Mick, who drives for Haas.
"It's so bad that you get marks on your body," said the 23-year-old German. "I'm glad the FIA has now responded to ensure our safety and health.
"It will be interesting to see if the measures will change the balance of power in the midfield."
Haas boss Gunther Steiner, meanwhile, agrees that Formula 1 had to act.
But he admitted: "Technical changes during the current season are always tricky.
"It inevitably affects the balance of power and then the question arises about whether that is fair.
"Of course it's about safety," Steiner added, "but it could have been corrected simply by raising the height of some people's cars."
"In Formula 1, there is always suspicion in such cases – you always think there is something behind it," said Steiner.
"But I think anyone who thinks like that in this case is going a bit too far."
