Mercedes team principal Toto Wolff has claimed there is "no holy cow" to solve the Silver Arrows' porpoising problems.
Lewis Hamilton and George Russell have suffered more than most drivers with the bouncing phenomenon caused by the ground-effect technology of this year's F1 machinery.
In Azerbaijan, Hamilton suffered so severely with back pain that Wolff suggested the seven-time champion may be forced to sit out this weekend's Canadian Grand Prix, a fear that has since been quashed.
Mercedes' unique disappearing sidepod concept is one reason behind the bouncing, as it leaves a chunk of the floor supported by only a single strake, meaning the team is unable to control its flexing as well as championship leaders Red Bull.
