McLaren has learnt the verdict of the FIA's investigation into its car post-Miami Grand Prix after Oscar Piastri secured victory.
On Thursday ahead of this weekend's Emilia Romagna Grand Prix, it was confirmed by the FIA that Piastri's car was chosen for a detailed post-race examination, alongside Charles Leclerc's Ferrari.
Specifically, motorsport's governing body investigated all four wheel assemblies of the MCL39 – this includes the wheels, drums and braking system.
The FIA revealed that everything was found to be in compliance with the technical regulations, deeming the car's much-discussed braking system as legal.
The FIA's document read: "After the race in Miami car #81 was randomly chosen among the top 10 cars for more extensive physical inspections.
"Subject to these physical inspections were the wheel bodywork assemblies."
Specifically, the FIA checked if the MCL39 was in compliance with both Article 31.3 of the technical regulations and Article 11.5.
The first surrounds the area of wheel bodywork, including the brake drums, wheel scoops, drum deflectors, internal cooling ducts and wheel covers.
As for Article 11.5, it covers liquids not being used by teams to help cool its brake systems. With McLaren's car having passed the investigation, it puts to bed any claim that tricks involving water are being used to cool its braking system.
