Van der Helm returning for full season in JDC-Miller 963

JDC-Miller MotorSports has confirmed Tijmen van der Helm will return to the driver line-up of its Porsche 963 for the full IMSA WeatherTech SportsCar Championship season.

The young Dutch driver has competed in the team’s Porsche 963 (pictured) in every race since the car made its debut at Laguna Seca in May 2023. He will be joined by Gianmaria Bruni. Tijmen hopes to celebrate his 21st birthday by receiving a Rolex wristwatch on the podium at Daytona later this month.

"I'm excited to keep working with everyone as we strive to

achieve our goals with the Porsche 963," said van der Helm. "With two years of GTP experience under my belt, I've learned a lot from my past teammates -- first with Mike Rockenfeller during our debut season, and then with Richard Westbrook in 2024. The team has made significant changes for 2025, and with the driver line-up recently announced, we have all the tools and potential needed to compete for race wins. I would like to thank John

Church and the Miller family for their faith and support in bringing me back.”

“I’m very pleased we are able to bring Tijmen back to our GTP program," said Church, JDC-Miller managing partner. "He has been with us throughout this journey, so no one is more qualified to get behind the wheel.

Now in his third year with us, he knows the series, the team, and the car, which are all invaluable to achieving success. We see Tijmen as very important to our program’s development. Not just in 2025 but in future years as well, so we have entered into a multi-year agreement with him.”
