In LMGTE Pro, the factory backed Porsche Team Manthey squad took both the win and secnod, running as two of four of the class cars to finish on the same lap.
In the LMGTE Am category, the Aston Martin Racing team swept the top two spots on the rostrum with the AF Corse F458 taking third.
The second safety car was called in the final hour for the heavy downpour, which eventually turned into a red flag at the 26 minute remaining mark as the rain continued.
