Flying Lizard Motorsports claimed overall honors in the third and final Pirelli GT4 America SprintX race of the weekend at Sonoma Raceway on Sunday.

Michael Dinan took the team’s No. 21 Aston Martin Vantage GT4 to a 21.369-second win over the No. 47 Nolasport Porsche 718 Cayman GT4 Clubsport of Matt Travis.

Dinan’s co-driver Robby Foley led from the green ahead of the No. 15 Bsport Aston Martin GT4 of Kenton Koch, with a slow stop by the team extending the gap during the mandatory pit stop and driver change.

Travis managed to get around the Bsport Aston of Bryan Putt on the final lap to take the runner-up spot for he and co-driver Jason Hart.

It marked Dinan’s first overall victory in GT4 America competition.

The No. 2 GMG Racing Porsche of Jason Bell and Andrew Davis finished fourth, ahead of the Rearden Racing Aston Martin, which resulted in three Aston Martins finishing in the top-five.

Saturday’s race-winning MarcoPolo Motorsports KTM X-Bow GT4 encountered turbo-related issues again, leaving the battle for GT4 Silver class honors between Tim Barber and Ryan Dexter in the closing stages.

Barber, in the No. 25 CCR Team TFB BMW M4 GT4, held off Dexter’s Ginetta G55 GT4 to take the class win.

GT4 Am class honors went again to the No. 7 Nolasport Porsche of Sean Gibbons and Zac Anderson, which finished ninth overall.

Cooper Extends GT4 Sprint Points Lead With Weekend Sweep

Michael Cooper swept the weekend in GT4 Sprint action with another controlling run in Sunday’s Race 3.

The Blackdog Speed Shop driver pedaled his No. 10 McLaren 570S GT4 to a 2.780-second win over the No. 66 TRG Porsche of Spencer Pumpelly in another rather incident-free race for overall honors.

It marked the first time a driver has won three races overall in the same weekend in GT class SRO America history.

Pumpelly dropped to fourth at the start following a flying run by the No. 18 Andretti Autosport McLaren of Jarett Andretti, who ultimately lost the position to the TRG driver on Lap 2.

Drew Staveley was next to come under fire by Pumpelly at the 20-minute mark.

Staveley completed the overall and Pro class podium in third in the No. 12 Ian Lacy Racing Ford Mustang GT4.

Jeff Burton claimed GT4 Am class honors in his Rearden Racing Aston Martin GT4.

The battle for the class win ended early due to an incident between Michael Dinan and Paul Terry that sent Terry spinning and Dinan into the pits to serve a drive-through penalty for avoidable contact.

It gave the No. 2 GMG Racing Porsche of Jason Bell a runner-up finish in class after electrical issues for the class pole-sitting SIN S1 GT4 of Mark Klenin.
