Verdonck/Kechele achieved a very memorable lap time of: 2:22.222mins - amazingly, that was where the clock stopped on the Ford duo´s fastest lap.

Martin Matzke and Yelmer Buurman, making a guest appearance in Belgium with Vita4One Racing Team had the quickest BMW Z4 GT3 and set the fourth fastest lap time ahead of the winners of the Oschersleben season-opener, Christopher Mies/René Rast in the Audi R8 LMS ultra (Prosperia C. Abt Racing).

Maximilian Götz and Maximilian Buhk (Polarweiss Racing) produced the sixth-fastest lap in their Mercedes-Benz SLS AMG GT3 ahead of the Porsche 911 GT3 R of the Danish mixed doubles pairing of Christina Nielsen and Allan Simonsen (Farnbacher Racing). A trio of BMW Z4 GT3s with Max Sandritter/Jörg Müller (PIXUM Team Schubert), Simon Knap/Jeroen den Boer (DB Motorsport) and Claudia Hürtgen/Dominik Baumann (PIXUM Team Schubert) rounded off the Top Ten.
