Mike Rockenfeller and Tijmen van der Helm join JDC-Miller MotorSports 2023 Porsche 963 GTP campaign in the IMSA WeatherTech SportsCar Championship.
Savage, Minnesota (April 26, 2023). 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.
Mike Rockenfeller, No. 5 JDC-Miller MotorSports Porsche 963
“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.”
Tijmen van der Helm, No. 5 JDC-Miller MotorSports Porsche 963
“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.”
Minnesota-based JDC-Miller MotorSports began making its mark on the IMSA record books with a PC class win at the 2016 Rolex 24 Hours At Daytona. The John Miller and John Church led operation quickly transitioned to the top ranks of sports car racing in 2017, scoring two second place finishes and fourth in the final class championship in only its rookie season.
The team’s success and growth continued in 2018, when they introduced a two-car effort and scored a victory at Watkins Glen and a pole position at Road America. Once again, JDC-Miller MotorSports finished fourth in the series championship despite racing an even larger and more competitive IMSA WeatherTech Championship field.
For the 2019 season, JDC-Miller entered into a partnership with Cadillac to field a two car Cadillac DPi-V.R effort. The program had a number of podium finishes and added the prestigious 12 Hours of Sebring crown to its growing list of accolades.
For the 2023 season, JDC-Miller MotorSports entered into an agreement with Porsche making it the first customer team selected to campaign the German sports car manufacturer’s Porsche 963 customer program. The Porsche 963 will compete in the new GTP category, which competes as the top class in the IMSA WeatherTech SportsCar Championship. The GTP Class introduces technically sophisticated hybrid power to IMSA matching it for the first time to efficient and bespoke internal combustion engines.
