Williams have modified part of their front suspension and mirror design to make the car legal for the season-opening Australian GP.
Its unconventional wing mirrors and part of the suspension generated much attention when the FW42 was unveiled during pre-season testing at the Circuit de Catalunya.
However, Motorsport.com has reported that the FIA were not happy with elements of the designs, and the team must now make modifications to ensure the car’s legality come Australia.
The FIA technical regulations state that only six suspension members are permitted: four wishbone members, one pushrod and one steering arm.
Williams introduced a thin, seventh member that runs along the edge of the lower wishbone, which will now be removed from the suspension for the first race.
The curved wing mirrors that were used throughout testing will change to a version not run before by the team.
After being well off the pace in testing, both Robert Kubica and George Russell, who will drive the FW42 this season, criticised the car, while Kubica declared himself only “20% prepared” for Australia.
It’s going to be a long, old season…
