Less than halfway into the 10-hour race, it rained and ended. Eeeeh.
After the Corvettes ran in tandem at the front for most of the racing, a tactical move by the Risi Competizione team got them the GT2 win. On the yellow flag period just before the downpour, the Ferrari changed to wet-race tires while its GT2 rivals were stuck with pitting under green. Game over.
