Dutchmen Jos Menten and Xavier Maassen dominated the qualifying race for the fifth round of the FIA GT1 World Championship at Spa.
Menten converted Maassen's pole into the lead of the race aboard the DKR-run Mad-Croc Chevrolet Corvette and edged away from Frank Kechele in the best of the Reiter Lamborghini Murcielagos through the opening stint.
The DKR crew maintained an advantage of more than two seconds during the mandatory pitstops, giving Maassen enough of lead over Ricardo Zonta to claim a comfortable victory.
Menten said: "I don't really think it was easy. I'd raced with Frank at Silverstone [in the Reiter Lambo] and I know what he is capable of."
Third place went to the Phoenix/Carsport Chevrolet driven by Marc Hennerici and Mike Hezemans. Hennerici ran fifth to the pitstops behind Dominik Schwarger and Stefan Mucke, but contact between the All-Inkl.com Lambo and the Young Driver AMR Aston Martin and then a fast pitstop by the Phoenix squad got Mike Hezemans out in third place.
Mucke and Christoffer Nygaard ended up fourth ahead of the Vitaphone-run Hegersport Maserati of Nico Verdonck and Bert Longin. Sixth place went to Schwarger and team-mate Nicky Pastorelli.
Championship leaders Michael Bartels and Andrea Bertolini non-scored in their Vitaphone Maserati after the former sustained body damage on the opening lap. Second-placed Romain Grosjean crashed the Matech Ford GT he shared with Neel Jani at Blanchimont.
