SAVAGE, Minn. (July 28, 2025) — It’s mid-summer, and the IMSA WeatherTech SportsCar Championship is two-thirds of the way through its 2025 season as the teams head to one of their absolute favorite tracks, Road America. For JDC-Miller MotorSports, it’s their home race, just a five-hour drive from their Minnesota headquarters. It’s the race where most of the team’s family, friends, partners, and especially fans get to see the team in action. It’s easy to love the beauty of the place, the uniqueness of the 4.048-mile, rolling circuit itself. And there is the speed. The days start with the famous brat and egg sandwich appropriately called an Egger, and end with a Spotted Cow ale.
Most of the JDC-Miller MotorSports team has a long history of racing at Road America. For Managing Partner John Church, his Road America experience started when he was 13, helping his father with his Formula Ford. John has rarely missed a year since then. Many team members share similar extensive experience at this iconic track. While the layout of the track hasn’t changed much since it was built in 1955, the facility has seen major upgrades. Some of us at JDC-Miller MotorSports feel a bit nostalgic for the charm of the old pagoda, the Billy Mitchell bridge, and having to trudge through the bushes to reach the far parts of the track. That feeling quickly fades when you drive through the tunnel into the infield, see all the modern buildings, and use the paved trails that extend to the farthest parts of the track.
Then there is the sheer performance of the team’s GTP-class Porsche 963 at Road America. From System Engineer Ryan Perera:
Max speeds – 310 kph (193 mph) into T1 and into Canada/T12
Apex speeds – 170 kph (103 mph) in T1, 90 kph (56 mph) in T5, 190 kph (118 mph) through the carousel with zero braking (just a lift-off throttle), and a 20% lift-off throttle through the kink at ~280 kph (174 mph)
Lateral g loads – 2.5g through T1/T5, the carousel sustains a neck-stretching 2.5g throughout, peaking at 2.8g. Out of the Carousel, the driver gets to take a quick breath before the 3.3g run through the kink. A space shuttle launch reaches about 3g, so don’t let anyone tell you GTP drivers aren’t athletes!
Energy mileage is a challenge at Road America – it’s the longest track and has the highest energy usage we’ll see all season. This makes it much harder to save enough energy to run an extra lap in a stint, but it also means there’s a bigger advantage if you can do it.
Every track is a unique engineering challenge. One fun aspect of Road America is the balance between less downforce/more top speed and more downforce to stabilize the car through the kink. The JDC-Miller MotorSports engineering team works very hard to give our drivers a car that they have confidence in everywhere around the track, but special emphasis has to be placed on the kink.
Last year, JDC-Miller MotorSports hosted St. Jude patient Colton, along with his mother and sister, at the Road America race. The team, IMSA, and Porsche welcomed them warmly, and the photos went viral. This year, they are returning to the race not just as representatives of St. Jude, but as new fans of the IMSA WeatherTech Championship.
Quotes:
John Miller, Partner, JDC-Miller MotorSports:
“Road America has always been our favorite track. Incredible racing layout in a beautiful setting. And my wife, Maggie, is from Manitowoc, Wisconsin – just up the road from Elkhart Lake. So we always have a lot of family joining us for the weekend. It is a very special event for us.”
Jessica Johnk, Professional Photographer, JDC-Miller MotorSports and Porsche:
“Going to Road America feels like a family reunion and a second home. The staff is always friendly and goes out of their way to take care of everyone on site. They maintain the facility to look its best, and the upgrades they add each season keep Road America at the top of the list for the best track in America.”
January 28, 2025
Daytona Beach, FL — Unitronic JDC-Miller Motorsports kicked off their 2025 IMSA Michelin Pilot Challenge season with a strong P7 finish in the BMW M Endurance Challenge at Daytona International Speedway. Competing in a stacked field of 27 GS competitors, the result marks an impressive debut for the team’s new Porsche 718 Cayman GT4 RS Clubsport and sets a promising tone for the season ahead.
Strong first showing for the #17 Porsche
With plenty of time to dial in the setup and get comfortable with the new race machine during the ROAR Before the 24, Chris Miller would start the 4-hour BMW M Endurance Challenge from P9 after Thursday’s qualifying session. His stint was marked by several battles to maintain position, allowing the #17 Cayman GT4 RS to remain on the lead lap.
Nearly two hours into Friday’s race, Mikey Taylor would take over the reins and impressively climb as high as P2, fending off numerous attacks from a chasing Ford Mustang GT4 duo. Ultimately, the team would have to settle for a P7 finish but the long race demonstrated the Porsche’s potential and provided many valuable insights for future improvements.
Drivers optimistic for season ahead
Chris Miller reflected, “After a long offseason and a ton of hard work by everyone involved in this program, it felt pretty special to finally get to drive our new race car. We knew there would be a lot to learn but the Unitronic JDC-Miller Motorsports crew was up to the task, changing components between every session as we worked to find a setup for the race. Thanks to their efforts, we made a lot of progress with the car and felt optimistic about our chances at a good result.“
“As racers we are rarely satisfied with anything but a win. Finishing seventh is not where we know we can be but it’s a solid start and a place we can build from. I think we showed ourselves that we have the pieces and potential to run at the front and we are all motivated and looking forward to Sebring already!“
Mikey Taylor added, “A great start to our new season with a new car! We knew it wasn’t going to be easy without any testing and learning the new class and car, but the team did a great job in preparing for the event as much as they could and we worked through everything we had time for! The speed in the race is something we can build on, and we know what we need to work on for Sebring! A very positive start to our relationship with Porsche and some good points to get the championship going!“
Next round just weeks away
Looking ahead, the Unitronic JDC-Miller Motorsports team is setting its sights on the next challenge at Sebring International Raceway. Known for its notoriously bumpy surface, the 3.7mi track will require the team to fine-tune their vehicle setup once more. Despite the upcoming challenge, the team is eager to tackle this next hurdle and build on their solid start for the second round of the 2025 IMSA Michelin Pilot Challenge Season.
