Harry Gottsacker and Jon Miller have been confirmed as drivers in ST Racing’s second BMW M4 GT4 for next weekend’s Pirelli GT4 America season-opener at Circuit of The Americas.

The duo join the previously announced pairing of Samantha Tan and Jason Wolfe, who will make a run for the GT4 West championship in the No. 38 BMW GT4.

The Gottsacker and Miller combination is currently confirmed for COTA only.

Gottsacker, who is taking part in a full season of IMSA Michelin Pilot Challenge with Bryan Herta Autosport, finished second in the GT4 America points standings last year, driving for Racers Edge Motorsports.

“We have worked very hard in the off season to put together a competitive program for the GT4 America series,” Gottsacker said.

“Jon Miller and ST Racing were winners in the Am category last year, and I’m looking forward to joining them at COTA.

“I’ve had a lot of success in Austin over the past few years in GT4 equipment and believe we are in a position to continue that trend. This is a home race for us and I look forward to it every year.”

Miller, meanwhile, competed in a partial season for the Canadian squad last year, scoring victory at Virginia International Raceway.

“Last year, COTA was the only SprintX race where I wasn’t behind the wheel, so I’m looking forward to starting off the season with Harry on the right foot at a track I know and enjoy,” Miller said.

“Aurora Straus and I had a fantastic 2018 season together in this car, landing on the podium multiple times – I’m looking forward to building on that experience with Harry.”
