Aston Martin #96 Vantage GTE triumphed in the GTE Am class.
New driver Nicki Thiim was impressive in his first outing with AMR Young Driver Vantage.
The race ended in an Audi one, two, three and a Ferrari double in LM GTE as the Italian cars triumphed in both Pro and Am.
It was a fine race for GT cars and the perfect dress rehearsal for the next round of the 2013 FIA World Endurance Championship and the biggest sportscar race in the world – the 24 Hours of Le Mans.
Under new regulations, each car must complete at least four laps with two drivers, with the qualifying lap calculated from the average of the best four laps.
The Aston Martin Vantage achieved an average of 2:21.265, just three hundredths of a second ahead of the 8Star Motorsports Ferrari 458 Italia of Matteo Malucelli and Rui Aguas.
The driver line-up for Le Mans will remain the same as at Spa except for Richie Stanaway who will be replaced in France by American Le Mans Series racer, Bill Auberlen, who celebrated victory at Long Beach last week.
