Eric Boullier admits the FIA's directive on FRIC suspension systems "came as a surprise", but don't think it will have much of an impact on McLaren.
FIA Race Dictor Charlie Whiting sent a letter to all teams on Tuesday stating that front and rear interconnected [FRIC]suspension systems could be banned at as soon as the German GP.
However, the sport's governing body will need to get the go-ahead from 11 teams before they can outlaw the system. Should the teams oppose their view, then the FIA will only be allowed to adopt the new rule for next season.
While Mercedes' system are believed to be the best on the grid, McLaren Racing Director Boullier says everyone is using it, but he's not too concerned about a possible ban.
"It came as a surprise. It's not based on any team action; it's an FIA action and we have been warned at the weekend that something could come out of this," Boullier said in a McLaren Mercedes phone-in on Wednesday.
"We've got this letter from Charlie Whiting, it's actually a technical directive. Most of the teams, if not all the teams on the grid, they are using this kind of suspension system, which is connecting a little bit different to use the best of the vehicle's dynamics.
"I think some teams may have been extreme, this is maybe why the FIA is questioning the legality of this system. And in the case of McLaren, we are quite relaxed to be honest. We don't see any issue with that for us.
"I don't think there would be too many disturbances for the rest of the season. We don't like it when there is a technical or sporting change during the course of the season, but maybe there is some reason behind why the FIA wants to do it."
Although some teams have benefitted more from it, Boullier feels a ban is unlikely to be a "game-changer" for anyone.
"It's a good question to be honest. I don't know the secrets of the designs of the other teams. I think for most of the teams it would not be a game-changer," he said.
"There is maybe a couple of teams who have been extreme and obviously who could be potentially in trouble to switch back to a non-connecting system.
"I don't know to be honest. But for most of the teams, I think it won't be a game-changer."
