The governing body for Formula 1 could ban the controversial 'T-wings' seen up and down the grid in 2017.
The aerodynamic appendages are unpopular from an aesthetic point of view, and there could also be a safety issue after two high-profile failures on the Mercedes car recently.
"I think they should be banned on the grounds of safety and cost," said Red Bull boss Christian Horner after a wing damaged Max Verstappen's car in Bahrain.
F1 has scheduled a meeting of the technical working group for next Friday, with the future of the T-wings and engine cover 'shark fins' on the agenda.
Mercedes was ordered by the FIA to strengthen its T-wing design in Bahrain, but boss Toto Wolff is not sure a ban is necessary.
"I can well imagine that Christian wants a part banned on a rival car," he said with a smile, insisting even a "baseball bat" would not damage the reinforced Mercedes T-wing now.
When asked if T-wings will be banned ahead of the forthcoming Russian grand prix, Williams technical boss Paddy Lowe answered: "I don't know. Ask (FIA Race Director) Charlie Whiting."
