Teams will be forced to make their "bridge wings" more stable for this weekend's Canadian Grand Prix, according to autosport.com.
The FIA's clampdown on so-called 'moveable aerodynamic devices' means teams must fit a supporting stay to the nose cone of cars to ensure the bridge wings do not move.
McLaren Mercedes were the first team to use such a wing - which spans the top of the nose section - last year and Toyota, Renault, Williams, Red Bull and Toro Rosso have all followed suit.
Renault are currently the only team whose central stay is FIA compliant.
On-board video footage shot during the Turkish Grand Prix showed the bridge wings could be flexing at high speed, apparently promoting the FIA to look into the matter.
