A single out-of-compliance part has excluded the overall winner from the World Endurance Championship’s 6 Hours of Silverstone results, reports . The No. 7 Audi R18 had worn its front skid block down to less than the required 20mm minimum thickness.

The too-thin skidplate was found in post-race scrutineering.

This gives the overall and LMP1-H class win to the No. 2 Porsche 919. The No. 6 Toyota TS050 then inherits second place, both overall and in its class.

Because this race was so on the WEC’s fastest top class of manufacturer-backed LMP1-Hs, the third place on the overall podium will go to a privateer LMP1: the No. 13 Rebellion R-One AER.

Per Sportscar365, Audi has the opportunity to appeal this decision. In the meantime, this is quite a bizarre way to start the WEC season.

According to , Audi did not submit an appeal, and official results have already been posted. The exclusion stands as is.

Contrary to the previous report that said Audi will not appeal the decision, Sportscar365 editor John Dagys just tweeted that Audi will lodge an appeal to the WEC:

Either way, we’ll have more information as this story develops.

: It’s official, Audi is appealing, per a statement released by the team:

Audi Sport Team Joest has appealed against the exclusion of winners Marcel Fässler/André Lotterer/Benoît Tréluyer. Hence the result of the 2016 FIA World Endurance Championship (WEC) season opener remains provisional.

The Stewards of the Meeting received a report from the Technical Delegate explaining that the thickness of the front skid block of car no. 7 doesn’t comply with article 3.5.6 a3 of the LMP1 Technical Regulations. Audi Sport Team Joest has appealed the decision to exclude the number 7 car from the results. Hence the race result will depend on the decision of a sport tribunal.

We’ll be on the lookout for the results of that tribunal and have them as soon as they’re ready.
