JDC-Miller MotorSports confirmed today that Mike Rockenfeller and Tijmen van der Helm will lead the driver lineup of the team’s new IMSA WeatherTech SportsCar Championship Porsche 963 entry in the GTP class. The Minnesota-based race team will debut the first customer effort in the prototype category at WeatherTech Raceway Laguna Seca on May 12-14.

Mike Rockenfeller’s sports car racing history is truly remarkable. A veteran of the Porsche Motorsport Pyramid, the German prodigy began his association with the brand in 2003 racing in the Porsche Carrera Cup Germany. His career spans multi-year stints as a factory driver for Porsche, Audi, and Corvette. He has wins at Le Mans (2), Daytona, Sebring, the Nürburgring 24 and a championship in the fiercely competitive German Touring Cars (DTM). With his infectious smile, the 39-year-old is a favorite in the paddock. His personality is a perfect fit for the JDC-Miller team bringing a wealth of knowledge and experience at the highest levels of sports car racing.

While anticipating the delivery of its Porsche 963, van der Helm competed with JDC-Miller MotorSports in its LMP3 class entry at both the Rolex 24 At Daytona as well as the Mobil 1 Twelve Hours of Sebring earlier this season. The championship-winning team owned by John Miller and John Church helped the Dutch driver celebrate his 19th birthday at Daytona with a top-five finish. In 2022, he competed in the FIA World Endurance Championship and the European Le Mans Series in the LMP2 class including his first start at the prestigious 24 Hours of Le Mans. A third driver for the Michelin Endurance Championship events will be announced at a future date.

“I am excited to be part of this team and the Porsche 963 project! Starting our GTP season at WeatherTech Raceway Laguna Seca for the fourth round of the season is going to be a challenge. I am confident the JDC-Miller MotorSports team is on a very steep learning curve and will compete with the GTP teams very quickly. So very happy to see my name back on a Porsche.”

“I am really happy to be a part of JDC-Miller MotorSports Porsche 963 LMDh project. To me it does not really matter that we start a bit later in the season. I think we as a team can maximize every opportunity we will get. Going to the Laguna race with a brand-new car will be tough, but I have no doubt that we will be competitive as a team. I look forward to the challenge and opportunity!”

John Church, Managing Partner, JDC-Miller MotorSports

“We are very proud to announce the new driver lineup for our 2023 GTP campaign with the Porsche 963. It represents a balance of youth and experience and features a tremendous amount of on-track success. This pairing combined with the Porsche 963 will allow us to compete for wins in IMSA.”
