ST Racing is pleased to announce that it will return to the GT World Challenge America (GTWC) as part of its racing program in 2023.
In a part-time campaign in GTWC America in 2022, Samantha Tan Racing completed solid outings at both Sonoma Raceway and Virginia International Raceway, during which the speed of the team’s BMW M4 GT3 was put beyond doubt, before Samantha Tan, Nick Wittmer and Harry Gottsacker rounded out the season with a Silver Cup class win and a top-10 finish overall at the Indianapolis 8 Hours.
Prior to that, ST Racing’s lofty accomplishments with SRO included both West Pro-Am Cup Teams’ and Drivers’ championships in 2019 and SprintX Teams’ honours in 2020, both as part of the Pirelli GT4 America series.
With momentum on its side, ST Racing will look to further establish the M4 GT3’s credibility on the North American stages in 2023. The #38 BMW will be driven at all rounds by team co-owner Samantha Tan, with her teammates set to be revealed in due course.

“I’m ecstatic to be back in the GTWC paddock again – this time for the full season,” said Tan. “We were met with many difficulties last year, which prevented us from competing at the majority of events, but we will once again step up for the challenge this upcoming season. This year, our BMW M4 GT3 will be run by the STR38 Motorsports crew, a team of highly experienced and dedicated engineers/mechanics from around the world managed by a familiar face, Jon Miller. I look forward to another great year of racing with SRO!”
The GTWC is scheduled to begin at Sonoma Raceway on March 30 to April 2, followed later that month with rounds three and four at NOLA Motorsports Park on April 28-30.
Rounds five and six take place on May 19-21 at Circuit of the Americas. The Texas facility has proven particularly successful for Samantha Tan Racing over the years, with the Canadian team taking SprintX Pro-Am and TC class wins at COTA in Pirelli GT4 America, as well as podium finishes in TC America.
Virginia International Raceway, another fruitful hunting ground for ST Racing, will host rounds seven and eight on June 16-18, with the GTWC North America returning to action at Road America on August 18-20, after the series’ summer break. After the penultimate weekend at the vaunted Sebring International Raceway on September 22-24, the GTWC North America draws to a close at Indianapolis Motor Speedway on October 5-7.
