Williams team principal has revealed how the F1 teams were able to convince the FIA to delay its new flexi-wing tests until round nine of the season. Flexi-wings were a matter of controversy throughout the 2024 campaign, with Red Bull in particular voicing concern over the front wings of rival cars. The FIA conducted an investigation and found no team to be in breach of what is allowed as per the regulations. However, over the winter break, it emerged the FIA was imposing stricter tests on the wings for the 2025 season. The new rules are set to be in place from the Spanish Grand Prix onward - however Williams team principal Vowles has revealed the FIA wanted to enforce them at an earlier date. But with Monaco posing its own risks due to its narrow layout, the FIA allowed the fresh directive to come after the trip to the Principality. “It was originally, I think round seven that they were going to change it,” Vowles told media including RacingNews365 . “We highlighted that it had Monaco in between, and it's really difficult for teams to effectively have the right stock of front wings for Monaco. “So we got deferred back to the race after Monaco.” Despite the late changes teams will have to make, Vowles does not think it will impact Williams as much as other squads. “Our wing was already along the pipeline of production when the rules changed,” Vowles admitted. “In terms of exploiting that area, I think you'll find all teams are doing what they can, but there are going to be teams that are more advanced in that area than others. “I don't think we're market-leading in that particular area. “However, what I can also say is the rule change around [race] nine doesn't particularly trouble us. “As a result of that, and it probably will have a more profound effect on others.”
