The results of the 2018 Italian Grand Prix would see the Williams team finish with Lance Stroll coming home in tenth. Team-mate Sergey Sirotkin was one place behind in eleventh but had been close to finishing in the points all race.

But after the race was concluded the Renault team would protest the legality of the Hass of Grosjean. After an investigation the stewards would announce that Grosjean's Haas was disqualified from the Italian Grand Prix after his car was found not to be in compliance with the regulations, in particular the statement said that the floor of the car was found to be in breach of the rules.

"The reference plane of car number 08 is found not to be in compliance with Article 3.7.1 d) and the clarifications given in TD/033-18 published on 25 July 2018," said the FIA.

The article mentioned states: "The surface formed by all parts lying on the reference plane must have a 50mm radius (+/-2mm) on each front corner when viewed from directly beneath the car, this being applied after the surface has been defined."

The failure of the Haas to comply with the regulations means it is disqualified from the results - and means Haas will move back behind Renault to fifth place in the constructors' championship.

As a result of this disqualification it elevated Sergey Sirotkin to tenth position seeing the Williams driver score his first point of the season.
