Reigning champion Maximilian Gotz led the 20-minute session after the opening runs on the wet track that returned to the calendar after a year's absence, the Winward Mercedes driver setting a benchmark time of 2m30.800s.
This put him just 0.007s ahead of SSR Performance Porsche driver Olsen, with Gotz's team-mate Lucas Auer adrift by exactly the same margin in third in Winward’s second AMG GT3.
