As was the case in the overall standings, GT1 saw the successful defence of a 2007 race win as Antonio Garcia, David Brabham and Darren Turner brought the #009 Aston Martin DBR9 home first in class in 13th overall after another race long battle with big rivals Corvette.
Although not quicker than the C6.R in qualifying, the DBR9 had the race pace to fight its way to the front and after getting into the lead, the new look Gulf-liveried Aston took the GT1 title ahead of the #63 Corvette of Ron Fellows, Jan Magnussen and Johnny O'Connell. An alternator issue delayed the #64 Corvette but it rebounded to take third in class after a battery problem sent the #007 Aston Martin of Heinz-Harald Frentzen, Andrea Piccini and Karl Wendlinger into the garage for repairs with the second works car taking the flag in fourth place.
Elsewhere in the class, the #72 Luc Alphand Corvette was fifth ahead of the sister car, while the Larbre Saleen, the Team Modena Aston Martin and the IPB Spartak Lamborghini all made it to the finish – although only just in the case of the latter as it completed exactly 70 per cent of the race distance.
GT2 was a Ferrari celebration after a race that just didn't go to plan for rivals Porsche.
Putting its disappointing ALMS form to one side, Risi Competizione led for much of the race after an early collision for the IMSA Performance and Flying Lizards Porsches and the late demise of the Virgo Motorsports Ferrari meant that Jaime Melo, Gimmi Bruni and Mika Salo were comfortable winners ahead of the BMS Scuderia Italia and Farnbacher Racing teams.
JMB Racing took fourth, while the two Porsches to make it to the finish were well off the pace after Felbermayr-Proton and the Lizards were left with long stops to make repairs to their respective cars.
