Max Verstappen feels that the FIA should check the front wings on all cars following the introduction of new tests on the rear wings that forced Red Bull to alter their rear wing for last weekend's French GP.
The flexi-wing saga has been a controversial topic this year and video footage has showed Mercedes' front wing flexing at various races this year. Red Bull advisor Helmut Marko has confirmed that the team have asked the FIA to check Mercedes' front wing.
"I guess Paul Ricard showed that everything has been dealt with correctly," Verstappen told RacingNews365.com and other select members of the press. "But I do think that when you are checking the rear wing, you should also be checking the front wing
"The front wing has a bigger effect on the car. It's up to the FIA now to do these checks, because clearly they have done checks on the rear wings."
Sergio Perez agreed with Verstappen's comments as pressure now turns to Mercedes regarding the legality of their front wing.
"I think it's up to the FIA to do all those check-ups," said Perez. "As Max says, I think the front wing is definitely much more powerful on a Formula 1 car these days than the rear wing.
"It's up to them really and they have all the information."
