[1][2] Katsumasa Chiyo, Wolfgang Reip and Florian Strauss won the event driving a Nissan GT-R Nismo GT3.
Matt Bell led the field in one of the M-Sport Bentleys, ahead of Laurens Vanthoor in the Phoenix Racing Audi with Chiyo in third.
As Chiyo built a gap over his rivals, a battle developed for second place, with Bell ahead of Vanthoor and Mucke.
Mucke made contact with Bell, sending him into a slide, while Vanthoor drove around the outside of both cars to take second place behind Chiyo.
Knighton & Scott O'Donnell were replaced by Frank Lyons (who moved from the withdrawn #69 car) and Chris van der Drift.
