Colin Garrett and Zac Anderson took top overall honors in Sunday’s Pirelli GT4 America round at Sonoma Raceway, putting AutoTechnic Racing back into victory lane.
Garrett, in the No. 51 BMW M4 GT4, finished ahead of the No. 97 Random Vandals Racing BMW of Kevin Boehm and Kenton Koch after the 60-minute race ended under full course caution due to a late-race two-car accident.
It came after Jonathan Neudorf was forced to pit his No. 23 TechSport Nissan Z NISMO GT4 with 12 minutes remaining with a suspected mechanical problem.
Neudorf, who was facing a two-second post-race time penalty for not meeting the minimum pit stop time, had been challenging Garrett for the lead and Silver class win prior to the car slowing on track.
Former IndyCar driver Matheus Leist in the No. 89 RENNtech Motorsports Mercedes-AMG GT4 led early on in the 60-minute contest until getting passed by Anderson on Lap 7, prior to the mid-race pit stops in the race.
Leist’s co-driver Michael Auriemma emerged in the overall lead but eventually dropped to third overall, yet still picked up Pro-Am class honors.
The No. 999 Hanley Motorsports Toyota GR Supra GT4 of Daniel Hanley held off Saturday’s race-winning No. 68 Smooge Racing Toyota of John Greesbreght for third in the Silver class prior to the race-ending yellow.
Curt Swearingin was sixth overall at the line and second in Pro-Am, having shared the No. 7 ACI Motorsports Porsche 718 Cayman GT4 RS Clubsport with Kay van Berlo, who was in the mix early on.
AutoTechnic doubled up on Sunday with taking Am class honors in the No. 53 BMW driven by Matt Million and Troy Lindstrom.
The race ended under yellow for an incident between the No. 099 Rotek Racing Porsche of Jaden Lander and Nick Shanny’s Carrus Callas Raceteam BMW, which collided and stopped on track with seven minutes to go.
Both drivers climbed from the cars under their own power.
