Le Mans 24 Hours GT2 winners Wolf Henzler and Marc Lieb were relieved to take Porsche back to the top of the class after two years of Ferrari dominance.
The Risi Competizione Ferrari 430 has won the class in the last two races and looked likely to challenge again after fighting the leading works Corvette in the early stages.
The No. 77 Felbermayr Porsche that Henzler and Lieb shared with 2007 class winner Richard Lietz couldn't match either, but moved forward as the pace of the race took its toll on those ahead. The trio eventually won the class quite comfortably, ahead of the Hankook Farnbacher Ferrari and the BMS Scuderia Italia Porsche.
"After two hours we knew we couldn't match the Risi Ferrari or the Corvettes," said Henzler. "It was like a sprint race so we just decided to drive our own race and it turned out good for us."
Lieb added: "After the last two years when we have struggled here and the Ferrari has been very strong, we are very pleased to come back and win for Porsche."
