Formula 1's governing body the FIA says it is taking steps on safety grounds to reduce the high-speed bouncing that has affected drivers this season.
Mercedes' Lewis Hamilton described the Azerbaijan Grand Prix as the "most painful" he had experienced and many of his rivals have also raised concerns.
The FIA has now issued a technical directive to teams setting out how it plans to tackle 'porpoising'.
The ninth round of the 2022 season takes place in Canada this weekend.
In a statement, the governing body said it decided to intervene following "consultation with its doctors in the interests of safety of the drivers".
'Porpoising' is caused by the floor of the car being sucked so close to the ground at speed that downforce is temporarily lost until the car's ride height increases, before pulling it back down again.
It is a phenomenon that has returned to F1 for the first time in 40 years this season as a result of the new car designs introduced to make the racing closer.
