Nico Müller returns to the JDC-Miller MotorSports Porsche 963 for the remainder of the 2025 IMSA WeatherTech Championship season

Katie Church on September 10, 2025

SAVAGE, Minn. (September 8, 2025) — JDC-Miller MotorSports is pleased to announce the return of Swiss Formula E driver Nico Müller to its driver lineup for the remaining two races of the season. Müller will join Tijmen van der Helm in piloting the No. 85 Porsche 963 for the Battle on the Bricks at Indianapolis and Petit Le Mans at Road Atlanta.

Müller competed for JDC-Miller MotorSports earlier this year at the Twelve Hours of Sebring, where the team had a strong performance until experiencing a brake issue late in the race, bringing the car home in 8th overall.   

Since Sebring, Müller has gained additional Porsche 963 seat-time by competing in the 6 Hours of Spa-Francorchamps and testing as the reserve driver for the Porsche 24 Hours of Le Mans campaign.

Quotes:

John Church, Managing Partner, No. 85 JDC-Miller MotorSports Porsche 963

“I’m really pleased to have Nico back with us to wrap-up the season. He was a great fit with the team when he was with us at Sebring. Got up to speed with the 963 very quickly, which is not an easy thing to do. We think he will give us that little bit of extra pace we are looking for. We finished this race 3rd last year, so our goal is to move up a step or two.”

Tijmen van der Helm, Driver, No. 85 JDC-Miller MotorSports Porsche 963

“It’s great to have Nico back with us for the Indy and Petit.  I very much enjoyed driving with him at Sebring. A great addition to the team.” 

Nico Müller, Driver, No. 85 JDC-Miller MotorSports Porsche 963

“I am very excited to be back with JDC-Miller MotorSports after our race together earlier this season at Sebring. We demonstrated good pace and great potential during the 12-Hour event. I’m looking forward to building on that performance straight away.

Hopefully, I can help the team make further progress in the two races at Indianapolis and Road Atlanta. I’m really excited to compete in these endurance races with this amazing team. I’m familiar with Indianapolis because, in 2021, I took part in an 8-hour GT3 race there. I haven’t raced at Road Atlanta yet, so I’m eager to get my first experience on that fantastic track. Petit Le Mans is on every driver’s bucket list, so I’m truly excited about this opportunity. We’re going to give it our best effort to achieve some good results for JDC-Miller MotorSports.” 

LOVE RACING. STOP CANCER. returns to the Battle on the Bricks.

JDC-Miller MotorSports finishes in the 10th position at Road America

Katie Church on August 11, 2025

SAVAGE, Minn. (August 3rd, 2025) — It was an uneventful home race weekend for the No. 85 JDC-Miller MotorSports Porsche 963 in front of a large group of incredibly loyal family, sponsors, and fans.

The JDC-Miller Motorsports No. 85 Porsche 963 qualified in 11th position, but the hardworking JDC-Miller Motorsports crew made some productive changes overnight before race day, successfully making the car more competitive for the race. Driver Gianmaria Bruno gained a spot at the start and worked his way up to 5th position with skillful driving and great team strategy. Unfortunately, he later got caught in traffic and lost the spot to the race-winning BMWs. After the pit stop and driver change, the No. 85 Porsche fell back to 10th and ran the rest of the race there without incident.

Our 2024 St. Jude patient family returned to Road America this year as race fans. Colton, now a cancer-free 11-year-old, hung out with the team and his IMSA friends. This marked the kickoff of JDC-Miller MotorSports’ St. Jude fundraising effort, again carrying the LOVE RACING. STOP CANCER. theme, which will culminate at the 6-hour race next month at Indianapolis.

Quotes:

John Church, Managing Partner, No. 85 JDC-Miller MotorSports Porsche 963

“Another tough race for the 85 Porsche 963.  We struggled with pace throughout the weekend.  The guys worked hard, giving the drivers a much better car for the race.  Many thanks to all our sponsors, family, and friends who came to support us at our home race.”  

Gimmi Bruni, Driver, No. 85 JDC-Miller MotorSports Porsche 963

“Thanks to a strong start and solid strategy, we managed to break into the top five at times today. Later on, I got held up in lapped traffic. Compared to yesterday, we took a step in the right direction with our Porsche’s setup. However, we still lack top speed on the straights. Hopefully, that will improve in the final two races, so duels with other competitors become more enjoyable again – that would be nice. “

Tijmen van der Helm, Driver, No. 85 JDC-Miller MotorSports Porsche 963

“Frustrating weekend. We didn’t have a lot for our competition. They didn’t need to fight us for position as they knew they could get the position a bit further down the road. The crew made the car better throughout the weekend, so that is good. I am looking forward to what we can do at Indy. 

JDC-Miller MotorSports Returns to Road America

Katie Church on August 6, 2025

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.”

JDC-Miller MotorSports finishes in the 10th position at Watkins Glen

Sophie Church on June 25, 2025

SAVAGE, Minn. (June 23, 2025) — JDC-Miller MotorSports has a long history of success at Watkins Glen International Raceway, including an overall win in 2018. While the team always strives for a top finish, the Glen presents a race that holds special significance for the drivers and crew. This made it particularly discouraging when the car simply lacked the pace to be competitive. In 2024, the team was permitted to run their Porsche 963 with a power output of 512 kW (696 hp); this year, they are limited to 480 kW (653 hp). Additionally, the car carries significantly more weight than last year.

The JDC-Miller Motorsports No. 85 Porsche 963 qualified in the 13th position in hot and humid weather, but the team was upbeat as they were less than 0.9 seconds behind the fastest Porsche. They were, however, 2.75 seconds off the pole, which was a harbinger of things to come on the 6-hour race day.

The race began under heavy overcast conditions, leading to light rain that intensified at the half-hour mark. This triggered a series of cautions, keeping the field relatively close for the first hour and a half. However, the sun eventually emerged, bringing back hot and humid conditions with temperatures nearing 90ºF. The 85 car persevered, working its way up to 8th place in a largely uneventful race, but ultimately couldn’t maintain the pace. While running in 10th close to the end, the team took a gamble on a fuel stop and ran the car out of virtual energy in T10. They were serving a stop-and-go penalty when the checkered flag waved, securing a 10th place finish.

Quotes:

John Church, Managing Partner, No. 85 JDC-Miller MotorSports Porsche 963

“A truly frustrating weekend. The drivers, the crew, and everyone on the team executed well. The bright spot is that we worked extremely hard to maximize everything we could from the car. When you don’t have the pace, you have to go off strategy, and that doesn’t always work out. Tijman drove exceptionally well for almost four hours in very tough conditions. We are eagerly looking forward to Road America.”

Gianmaria Bruni, Driver, No. 85 JDC-Miller MotorSports Porsche 963

“It was a difficult race. We knew before the start that it was going to be very, very challenging. In the initial part of the race, we kept the car on the track despite some tough conditions. We will keep working, we keep chasing, we’ll see what’s coming next at Road America.”

Tijmen van der Helm, Driver, No. 85 JDC-Miller MotorSports Porsche 963

“Difficult weekend for all the Porsches at the moment.  We just don’t have the power on the straight and coming out of the corners like the others.  Really frustrating.  We hung in there, but this was really all we had.”

JDC-Miller MotorSports finishes in the 11th position at Detroit

Sophie Church on June 2, 2025

SAVAGE, Minn. (June 2, 2025) — JDC-Miller MotorSports persevered with their Porsche 963 after receiving a pit speed penalty, ultimately finishing in 11th place at the 5th round of the IMSA WeatherTech Championship on the streets of Detroit.

The privateer team felt confident heading into Saturday’s race after making progress on Friday with the car setup for the always-challenging Detroit street circuit. Some of this progress, however, was diminished on race day when the weather dropped significantly from the upper-70s to a blustery 61ºF. The cooler ambient temperatures made it more difficult to reach optimal tire temperatures during the race, which impacted the Porsche’s overall pace.

Gimmi Bruni had a strong opening lap in the No. 85 Porsche, passing two cars and advancing from his 10th starting position to 8th. The race was proceeding smoothly and according to plan when, on lap 21, Bruni pitted for the mandatory driver change to Tijman Van der Helm. Unfortunately, the No. 85 Porsche exceeded the pit speed limit while exiting the pits. A drive-through penalty was imposed, causing the car to go a lap down. Van der Helm uneventfully brought the car home in 11th position.

Quotes:

John Church, Managing Partner, No. 85 JDC-Miller MotorSports Porsche 963

“Except for the pit speed penalty, it was a relatively uneventful weekend. The team did a great job prepping the car for this race and provided the drivers with a car that performed as well as could be expected over the bumps and tight turns of this street circuit. While we didn’t achieve the pace we desired, we had a car we thought we could gain some positions with in the race. In a race as short as this one, once you go down a lap, there wasn’t much left to salvage. It’s tough. 

The crew and drivers did an excellent job throughout the weekend. We are excited about Watkins Glen and the rest of the season. We have experienced success at The Glen in the past and are putting in the effort for a strong performance.”

Gianmaria Bruni, Driver, No. 85 JDC-Miller MotorSports Porsche 963

“We knew this race was going to be tough for us for a variety of reasons.  I had a really great start, jumping up from P10 to P8.  We were in a pretty good position to push for the rest of the race from there, but the pit overspeed violation ended that.”

Tijmen van der Helm, Driver, No. 85 JDC-Miller MotorSports Porsche 963

“Over the weekend, we couldn’t quite match the pace of Porsche Penske Motorsport’s factory Porsche 963 cars. But in the race, the gap was a bit smaller. Sadly, a penalty for exceeding the speed limit in the pit lane cost us dearly – you simply can’t make up those 25 lost seconds. And even if you did, overtaking is difficult on this track.”

JDC-Miller MotorSports finishes in the 9th position at the 2025 Monterey Sportscar Championship

Katie Church on May 11, 2025

SAVAGE, Minn. (May 11, 2025) — JDC-Miller MotorSports brought their Porsche 963 home in an unsatisfying 9th position at the checker of the Monterey Sportscar Championship at WeatherTech Raceway Laguna Seca. Gianmaria Bruno had qualified the car in the 10th position.

Under beautiful, but cool California skies, 36 cars took the green flag for the two-hour and 40-minute race around the 2.238 mile circuit.  The LMP2 class was not part of this event. 

Bruni had a good start and maintained his position. The team planned to deploy an aggressive pit strategy to gain positions using an “undercut”, which was pitting early on lap 21 to get on new tires and in clean air. This strategy played out quite well, as competitors pitted and Bruni worked the No. 85 Porsche up to as high as 4th. To make this strategy work, however, you then need a full-course caution. Unfortunately, this race was unusually green from flag to flag, and a late stop for fuel left the No. 85 in 9th.

Looking ahead, the team is already focused on their next challenge at the Detroit Grand Prix, scheduled for May 31st. With the unique demands of the Detroit street circuit, JDC-Miller MotorSports is determined to find the speed and precision required to return to the front of the pack.

Quotes:

John Church, Managing Partner, No. 85 JDC-Miller MotorSports Porsche 963

“We didn’t have quite the pace we would have liked all weekend.  That resulted in a disappointing 10th qualifying position, so we knew we needed to come up with a strategy for the race that would move us up the order. We got aggressive and pitted on lap 21, which worked out very well. The downside was, however, that this strategy required a full-course caution, which we never got. That meant we had to stop for fuel late in the race, and we were back where we started. I can’t recall a race here that went the whole way without a full-course caution, but this year’s race did.

The crew and the drivers did a great job all weekend. IMSA racing is so competitive that if you are off by a couple of tenths here and there, you are going to finish 9th or 10th.  I’m confident that when we study the data, we will learn where those tenths are, and make the adjustments we need to be up front at Detroit.”

Gianmaria Bruni, Driver, No. 85 JDC-Miller MotorSports Porsche 963

“This was an interesting race. We tried to get the best out of it from the strategy, unfortunately, we needed a yellow that didn’t come. We gambled on a strategy, which sometimes works and sometimes not, and that is racing.

I think we did the right things for the position we were in. There wasn’t much else we could do to improve track position. It was good. We tried our best this weekend and now we move forward.”

Tijmen van der Helm, Driver, No. 85 JDC-Miller MotorSports Porsche 963

“We were struggling a bit with pace this weekend, and we just wanted to take a gamble on the strategy to maybe have a better result. 
It didn’t work out so well because we never got the safety car we were expecting. When you look at this race, normally there are several safety cars. So luck just wasn’t on our side. We will put our heads together to find some more speed in the car for Detroit and beyond.”
