Nicolai Elghanayan and Mads Siljehaug broke through to claim their first Pirelli GT4 America SprintX victories following a flag-to-flag run for the MarcoPolo Motorsports KTM X-Bow GT4 in Saturday’s Race 2 at Sonoma Raceway.
The Silver class pairing, who were denied the win on Friday due to turbo-related issues to their car, cruised to a 16.989-second win over the No. 21 Flying Lizard Motorsports Aston Martin Vantage GT4 of Michael Dinan and Robby Foley, which picked up GT4 Pro-Am class honors.
It was Elghanayan’s first GT4 America win since the Canadian Tire Motorsport Park Sprint round last year and Reiter Engineering factory driver Siljehaug’s maiden win on U.S. soil.
Bryan Putt held off a hard-charging Sean Quinlan for third overall and second in Pro-Am in the No. 15 Bsport Aston Martin GT4 that was started by Kenton Koch.
The two cars crossed the line in a near photo-finish in the end.
The No. 47 Nolasport Porsche 718 Cayman GT4 Clubsport of Matt Travis was forced to relinquish third overall in the closing stages of the 60-minute contest because of a drive-through penalty due to missing the pit window.
It was one of a number of cars to be assessed penalties in the incident-filled race.
Travis and co-driver Jason Hart, who claimed top honors on Friday, were relegated to a 9th place finish overall.
GT4 Am class honors went to the No. 16 Rearden Racing Mercedes-AMG GT4 of Kris Wilson and John Allen, which finished 11th overall following an impressive opening stint by Wilson.
The third and final race of the weekend gets underway at 9:30 a.m. PT/12:30 p.m. ET.
RESULTS: Race 2
