Teams to change wing design
Clampdown after video footage shows evidence of flexing
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 **** 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.
