McLaren has been summoned to the Formula 1 stewards because both of its cars are in an alleged breach of plank wear rules after the Las Vegas Grand Prix.
Both McLaren cars of Lando Norris and Oscar Piastri have failed to meet the thickness requirement of the rear skid block, which usually results in disqualification.
AdvertisementAdvertisementAdvertisementIt is in relation to Article 3.5.9 e) of the 2025 F1 technical regulations, which states “the thickness of the plank assembly measured normal to the lower surface must be 10mm ± 0.2mm and must be uniform when new”.
“A minimum thickness of 9mm will be accepted due to wear and conformity to this provision will be checked at the peripheries of the designated holes,” the article adds.
This comes after Norris finished runner-up to Max Verstappen in Vegas, with Piastri crossing the line in fourth behind third-placed George Russell.

Leclerc’s Ferrari team-mate Lewis Hamilton was also thrown out of the China results due to excessive wear on his rear skid block.
Two races later Nico Hulkenberg was disqualified in Bahrain because his Sauber’s rear skid block failed to meet the minimum thickness requirement, but none of them had finished on the podium like Norris did in Vegas.

That handed victory to then-team-mate Hamilton, who also lost a podium through disqualification the year before at the United States Grand Prix. It came after his Mercedes had excessive wear on his rear skid block.
