Former Porsche factory driver Rockenfeller, who set a distance record that still stands on his way to Le Mans victory in 2010 aboard Audi's R15-plus, will race the 2021 Sebring 12 Hour-winning team's newly-delivered car from the 12-14 May Laguna Seca round onwards.
He will share with 19-year-old Dutchman Tijmen van der Helm, who finished fourth in the LMP2 class on his Le Mans debut in 2022 and raced with JDC's LMP3 arm in the opening IMSA rounds of 2023 at Daytona and Sebring.
A third driver for the remaining endurance races at Watkins Glen and Petit Le Mans will be announced at a later date.
“I am excited to be part of this team and the Porsche 963 project!” said Rockenfeller, who will race at Le Mans this year as part of the Garage 56 NASCAR initiative with a Hendrick Motorsports-run Chevrolet Camaro.
“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.”
