Red Bull senior advisor Helmut Marko commended the FIA for its action against McLaren's controversial low-drag rear wing, which appeared to create a partial DRS

Protests from Red Bull, among other rival Formula 1 teams, have prompted leaders McLaren to make changes to their rear wing designs 'after conversations with the FIA'

AMuS journalist Tobi Gruner wrote on social media: “Breaking: After a successfull Red Bull complaint with the FIA, McLaren has to modify its low downforce rear wing. Bending of the flap edges on the straights will not be allowed, even if the wing passes the static deflection tests.”

Despite earlier reassurance and passing the FIA’s static deflection tests, McLaren will be forced to modify its low downforce, ‘mini DRS’ rear wing after the FIA received official complaints from Red Bull.

Formula 1’s governing body says McLaren’s rear wing complies with the rules after rivals Red Bull raised questions about its legality.

The FIA has asked McLaren to modify the rear wing in two places. The flexi-wing on the MCL38 now has to be modified.
