Audi Sport Team Sainteloc leads the Total 24 Hours of Spa at three-quarter distance with a six-car lead battle beginning to form.
Frederic Vervisch is out front in the No. 25 Audi R8 LMS GT3 he shares with defending race winners Christopher Haase and Markus Winkelhock, but is due a pit stop.
ROWE Racing has led most of the last three hours with its No. 99 BMW M6 GT3 which came out on top following the mandatory technical pit stops.
The car runs in fifth position with six hours to go, with Jens Klingmann having recently pitted.
The lead battle includes the Sainteloc and ROWE cars along with the Black Falcon and AKKA ASP Mercedes-AMG GT3s, No. 7 Bentley Continental GT3 and Walkenhorst Motorsport BMW.
The Sainteloc, ROWE and Black Falcon cars benefitted from serving their mandatory technical pit stops immediately before a Full Course Yellow was called, promoting them up the order.
While the race has begun to calm down, its tenth FCY period was called after a three-car collision which included the Team75 Bernhard Porsche 911 RSR, No. 8 Bentley and Aust Motorsport Audi.
Andy Soucek collided with Laurens Vanthoor and Tobias Dauenhauer, which caused the Bentley, which was already running behind after problems earlier in the race, to raise up into the air.
The car went to the garage and went back out on track before stopping on the circuit.
