Tijmen van der Helm has signed a long-term contract with JDC-Miller Motorsports, having been confirmed for his third season with the Minnesota-based team in the IMSA WeatherTech SportsCar Championship.

The Dutch rising star will join the previously confirmed Gianmaria Bruni in the team’s No. 85 Porsche 963 in the GTP class, looking to build on the John Church-led squad’s steady progress in the top prototype ranks.

Van der Helm has been with JDC-Miller since the formation of its customer Porsche GTP program that kicked off at WeatherTech Raceway Laguna Seca in 2023.

“I’m very pleased we are able to bring Tijmen back to our GTP program,” said Church. “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. The entire JDC-Miller MotorSports team looks forward to another year with Tijmen leading us to a championship.”

Van der Helm added: “I have really enjoyed my time with the team so far, and I’m excited to keep working with everyone as we strive to achieve our goals with the Porsche 963.

“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 lineup 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.”

The duo will be joined by ABB FIA Formula E world champion Pascal Wehrlein for the season-opener, with Indy NXT driver Bryce Aron completing the lineup in an expected Michelin Endurance Cup role.
