Kuno Wittmer and Michael Mills have scored a come-from-behind victory in Sunday’s Pirelli World Challenge SprintX Race 2 at Canadian Tire Motorsport Park.
Mills edged out the No. 14 GMG Racing Porsche 911 GT3 R of Brent Holden by 18.526 seconds for a sweep of the weekend by the Mills Racing crew.
Wittmer, who started second, was forced to serve a drive-through penalty early in the 60-minute race after receiving outside assistance on the grid to start its BMW Z4 GT3.
The BMW North America factory driver dropped to 4th and nearly 30 seconds behind but charged through the field prior to the pit stop and driver change to Mills with 25 minutes to go.
Mills rejoined in second and got around Holden less than five minutes later with ease to cruise to the win.
Holden and Colin Braun, who led the early laps, finished second, with a hard-charging Lars Viljoen in the No. 4 De La Torre Racing Aston Martin V12 Vantage GT3 slowing on the final lap.
Viljoen made up nearly 30 seconds in his stint, but ran out of fuel.
A late-race spin by Dion von Moltke initially dashed hopes of a podium finish for the No. 69 M1 GT Racing Audi R8 LMS ultra, which ran third in the hands of David Ostella in the opening stint.
However, the late issues for the Aston promoted von Moltke and Ostella to third, ahead of the team’s sister new-generation Audi of Walt Bowlin and Guy Cosmo in fourth.
Max Riddle and Kris Wilson also made it a clean sweep of the weekend in GTS, with the TRG-AMR pairing taking top honors in class.
Riddle edged out the team’s sister No. 09 Aston Martin Vantage GT4 of Derek DeBoer by 26 seconds for the class win.
The No. 45 Racers Edge Motorsport SIN R1 GT4 failed to finish after battling gearbox issues.
RESULTS: Race 2
