Advanced Metrology Accelerates Performance for Sportscar Race Team

Sophie Church on June 28, 2025

From Tooling & Production – Strategies For Large Metalworking Plants

In motorsports, where aerodynamic efficiency and mechanical accuracy can mean the difference between a podium finish and a mid-pack result, precision isn’t a luxury — it’s a necessity. As Brian Winters, Product Manager at Hexagon Manufacturing Intelligence, writes, Minnesota-based JDC-Miller MotorSports understands this better than most.

Competing in the top-tier GTP class of the IMSA WeatherTech Sportscar Championship with the Porsche 963, JDC-Miller Motorsports is embracing advanced metrology to optimize vehicle performance.

The JDC-Miller MotorSports team includes the Porsche 963 GTP LMDh in the IMSA WeatherTech SportsCar Championship.

Founded in 1969, IMSA is the premier sportscar racing series in North America, hosting such iconic races as the Rolex 24 at Daytona and the 12 Hours of Sebring. Both are races that drivers around the world aspire to have on their resume. Manufacturers such as Porsche, BMW, Acura, and Cadillac are heavily involved. The GTP class features highly advanced hybrid drive systems as well as other cutting-edge technologies.

Through a new partnership with Hexagon’s Manufacturing Intelligence division, JDC-Miller is integrating high-precision measurement technology into its workflow to enhance consistency, compliance, and overall race-day efficiency.

Precision and Compliance: The Foundations of Performance

Racing in IMSA’s highly competitive, sometimes rough and tumble, GTP class means operating within strict regulatory tolerances — teams are allowed only a 3mm deviation from factory-body specifications. These tight margins leave little room for error, making precise measurement a critical component of pre-race preparation.

Before partnering with Hexagon, JDC-Miller relied on jigs and manual measurements, a process that was both time-consuming and prone to minor inaccuracies. The introduction of advanced metrology tools has significantly reduced the margin for error, ensuring compliance from the moment the car comes off the truck.

“Before, we were using jigs that we built ourselves — rudimentary measurements that got the job done but left room for error,” said John Church, Managing Partner at JDC-Miller MotorSports. “With Hexagon’s scanning technology, we’ve eliminated that uncertainty. We’re now able to establish a precise baseline for the car before we even get to the track, which means less troubleshooting and more focus on performance.”

JDC-Miller uses Hexagon’s MARVELSCAN to scan the car before and after each race weekend to see exactly what’s moved and what needs adjustment.

Unlocking Performance with Advanced Scanning

At the heart of the partnership is Hexagon’s cutting-edge 3D portable scanner, MARVELSCAN, which captures millions of data points in seconds, creating highly detailed digital models of the vehicle’s exterior and components. This allows engineers to quickly identify deviations from optimal specifications, enabling them to make necessary adjustments before the car takes to the track.

The scanner’s advanced features — such as edge detection, built-in photogrammetry, the ability to scan reflective surfaces, and scanning without targets — make it particularly well-suited to the complex geometries, large objects and lightweight composites used in motorsports.

“With all the different curves and surfaces on these cars, it’s nearly impossible to measure accurately using traditional methods,” Church said. “MARVELSCAN changes that. We can scan the car before and after each race weekend and see exactly what’s moved, what’s changed, and what needs adjustment. That level of detail helps us fine-tune everything — from body panel fitment to suspension alignment.”

Beyond compliance, metrology technology enables JDC-Miller to optimize aerodynamics and structural integrity. By catching even the smallest inconsistencies, the team can make data-driven adjustments that enhance overall performance. Whether it’s verifying the precision of newly installed components or ensuring a perfect fit between subassemblies, accurate measurement reduces repair time and improves reliability.

From Workshop to Trackside Advantage

JDC-Miller is now incorporating metrology into its standard workflow, scanning the cars before each race weekend and after any incidents to assess structural integrity. By comparing pre- and post-race scans, engineers can quickly determine whether components have shifted or sustained damage, allowing for faster repairs and more consistent performance. This proactive approach not only saves time during trackside inspections but also minimizes the risk of undetected misalignments that could hinder race results.

MARVELSCAN fits perfectly in the hand and is light enough to take anywhere to scan for hours.

“There’s never enough time at the track,” Church explained. “The last thing we want to do during a race weekend is double-check things we should have already validated at the shop. With metrology, we know exactly what we’re working with before we even roll the car off the truck.”

The benefits were on full display during the grueling Rolex 24 At Daytona.

Over 24 hours, JDC-Miller executed 32 pit stops, fueling the car and changing 21 sets of tires — each stop averaging under a minute. “We compete with all the other teams in the pits as well as on the track. The goal is to minimize the amount of time the car is stopped. At Daytona, we were among the very best at quick and efficient stops,” Church said. “That level of efficiency is a game-changer. Consistency in setup means fewer surprises, and fewer surprises mean more confidence in the car for the driver and the crew.”

Bridging Technology and Expertise

To ensure seamless adoption of this technology, JDC-Miller is working with Productivity Quality, Inc. (PQI), a regional metrology expert providing hands-on training and ongoing support. PQI’s expertise is helping the team master the scanning process and best practices in measurement analysis. Over time, JDC-Miller aims to take full ownership of the technology, using remote support from PQI as needed.

The handheld scanner allows you to reach into hidden areas to get the right inspection angle without line-of-sight restrictions.

“When we first started looking for a scanning partner, we knew we needed more than just the best equipment — we needed a team that could help us leverage the technology and integrate it into our workflow,” said Roger Johnson, Partner Relations at JDC-Miller MotorSports. “Hexagon and PQI have been great in that regard. The equipment is user-friendly, and with PQI’s guidance, we are quickly gaining proficiency. The team is already identifying new opportunities to find uses for the technology that go far beyond what was initially anticipated.”

This collaboration highlights the growing role of metrology in motorsports, where even the smallest deviations can impact performance. By incorporating precise measurements into their workflow, JDC-Miller is positioning itself for greater consistency, faster repairs, and more predictable performance outcomes.

Looking Ahead: Innovation Beyond Compliance

As the partnership evolves, JDC-Miller is exploring additional applications for metrology beyond regulatory compliance and damage assessment. This includes creating digital molds of body panels and subassemblies for rapid repairs, as well as using CAD-to-part comparisons to prevent rework during assembly. By leveraging accurate data throughout the vehicle lifecycle, the team aims to streamline maintenance processes and improve long-term reliability.

“We’ve barely scratched the surface of what this technology can do,” Church said. “We’re looking at scanning body panels to create digital molds for repairs, analyzing subassemblies before installation to prevent rework, and even using real-time data to refine our performance strategy. The possibilities are endless.”

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.”

JDC-Miller MotorSports finishes in the 10th position at the 2025 Grand Prix of Long Beach

Katie Church on April 12, 2025

SAVAGE, Minn. (April 12, 2025) — JDC-Miller MotorSports brought their Porsche 963
home in a disappointing 10th position at the conclusion of the 2025 Grand Prix of Long
Beach. The 100-minute race around the 1.968 street circuit represented a sharp
contrast to the first two rounds of the IMSA WeatherTech SportsCar Championship.
IMSA competitors went from the two longest races on the schedule to one of the
shortest. This year’s race represented the 50th running of this popular and iconic race
around the Long Beach harbor.

Starting in the 9th position, the race started strong for the JDC-Miller MotorSports no. 85
Porsche 963 as Tijmen van der Helm picked up a spot on the start and had excellent
pace. His day was short, however, as a caution came out twenty minutes into the race.
The team pitted to take advantage of the yellow for the mandatory driver change to
Gianmaria Bruni. The JDC-Miller crew had an outstanding stop, and when the race
resumed, the 85 was running in a very strong 5th. Gimmi was running with the leaders
when on lap 40, a GTD car he was lapping, hit the left rear of the Porsche and spun him
into the tire wall. This forced a pit stop to repair a broken rear wing. The JDC-Miller
team made the repair in less than a minute, keeping the car on the lead lap, but the 85
dropped to 10th, where it would remain until the race’s conclusion 20 laps later.

The car will stay on the West Coast for the next race at WeatherTech Raceway Laguna
Seca May 11th. It was just 2 years ago that JDC-Miller MotorSports debuted their new
Porsche 963 in the IMSA WeatherTech SportsCar Championship GTP class.

Quotes:

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

“We were not happy with our qualifying set-up and the crew did a great job overnight to
give us a really good car for the race. Tijmen showed that right away with an over-take
on the first lap, and we were feeling confident of a good result. When the first caution
came out, everyone did an awesome job in the pits, and we vaulted up to 5th.
Unfortunately, as so often happens on a street course, Gimmi had an incident and we
had to pit to repair the rear wing. With only a little over a half hour left in the race, there
just isn’t much you can do.

A disappointing finish, but there were some real bright moments. We had a competitive
car and executed very well. If we keep doing that, we will be in a great position when
Lady Luck does smile on us.”

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

“A tough finish which doesn’t reflect how competitive the car was. The car was very
good, and we were running strong until, in turn 6, I got hit in the left rear corner by a
GTD car I had just lapped. It spun me around into the tire wall, damaging the wing and
diffuser. It’s a shame because we were doing very well. We’ll move forward.”

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

“This is a very short race for our series. We had to come from the back as we struggled
with the setup in qualifying. The car was much better in the race, and we picked up
some spots early in the race. Sadly, we got hit by a GTD car and had to make an extra
pit stop. Just not the luck on our side. We will keep improving and get some results at
Laguna Seca.”

JDC-Miller MotorSports brings home the No. 85 Porsche 963 in the 8th position at the 2025 Twelve Hours of Sebring

Katie Church on March 17, 2025

SAVAGE, Minn. (March 17, 2025) — JDC-Miller MotorSports brought their Porsche
963 home in the 8th position at the conclusion of the Mobil 1 Twelve Hours of Sebring in
front of a record crowd for the 73rd running of the classic race. This year’s “12 Hours”
lived up to its reputation as one of the toughest races in the world for both man and
machine. Sebring is famous for its bumpy airstrip surfaces and intense multi-class
traffic, especially with 56 cars starting on the 3.74-mile circuit. This year had an
additional challenge as temperatures soared to nearly 90°F in the midday Florida sun.

The JDC-Miller MotorSports team had a setup strategy of running a slightly
compromised setup during the heat of the day which allowed the handling of the car to
be optimal when the sun went down and temperatures cooled. Even with the
compromised setup, the No. 85 Porsche 963 was quite competitive in the heat of the
day, running as high as 3rd mid-day the strategy played out. After close to 9 hours of
hard racing, however, the left front brake rotor failed. Lady luck smiled on the No. 85
Porsche as a caution came out just as the team needed to pit the car. Quick work by the
crew got the LF brake replaced with the loss of only one lap and the team was optimistic
that with three hours remaining, they could get the lap back and make a charge to the
finish. Unfortunately, there wasn’t the usual series of yellows that are typical of the final
hours of this race, and the No. 85 Porsche soldiered on in the 8th position for the
checker.

Quotes:

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

“A challenging and a bit disappointing day for us. We struggled to find the balance on
Thursday, which is the only practice we get for the 12 Hours. Working late Friday
evening, we made a good step forward, so during the race we had good pace.
Unfortunately, the issue with the brake rotor put us a lap down, and the way the race
played out, we were never able to recover. Disappointing as we were on track to finish
4th or 5th, but that’s Sebring.

We will take what we learned here and focus forward to Long Beach. Thanks to Gimmi,
Tijmen, and Nico, for their great performances and bringing the car home in one piece
after a challenging 12 hours.”

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

“Great job by everyone on the team for a solid 8th place finish in what I think is the
hardest race of the season. The crew did an amazing job. We tuned up the car with the
engineers Friday night and went in the right direction. In the race, the car was really fast
in very hot conditions. Unfortunately, we had an issue with about 3 hours to go. The
front left brake disc failed and had to be changed. From there on, the car was not as
good under braking, which is critical for these cars. We were able to hold our position
and finish the race. Thanks to the team, Tijmen, and Nico. It’s not the result we wanted,
but I think it was the best we could achieve at Sebring today.”

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

“With only qualifying on Friday it is hard to put everything together with the setup before
the race. We had been struggling to find the setup on Thursday, but the guys worked
hard on Friday night to make some changes. In the race, the car was quite good.
Unfortunately, our luck ran out, and we had some brake problems. That can happen in
long races like Sebring. We do have some positive things to take away. There is work to
do, but we are on track for some good results later in the year. The pace is there, so if
we can put everything together, we should have success.”

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

“What a weekend with JDC-Miller MotorSports at the 12 Hours of Sebring! My first laps
in the Porsche 963. To be taking the checkered flag in that beautiful yellow car at the
end of the Sebring 12 Hours was a thrill. We were competitive most of the race. We had
a really fun race going until the brake issue developed, which threw us back.
Unfortunately, there weren’t enough yellows at the end to recover the lost lap. It was a
bit of a pity as our pace had been strong. After trying to fix the issue, we weren’t quite
as strong anymore as we struggled with general brake performance on the car. I think
we were on track for a top 5. That would have been great in this tight competition. I felt
at home with the team and in the car and enjoyed returning to IMSA. Thanks to JDC
Miller MotorSports and Porsche for having me. Hopefully, we’ll be back soon.”

SAVAGE, Minn. (January 27, 2025) — JDC-Miller MotorSports secured 6th place in
the 63rd running of the Rolex 24 Hours of Daytona with their Porsche 963 GTP. The
team completed 780 laps of the 3.54-mile Daytona road course, finishing just 109
seconds behind the overall winning No. 7 Porsche. The car averaged 115.439 MPH
over the 2,774 miles it covered during the race.

The chilly Florida temperatures posed a challenge for the team, starting at 59°F and
dropping to 48°F by 3 AM. All four drivers had to skillfully manage tires and brakes that
were difficult to get up to and maintain the desired operating temperature. The No. 85
Porsche began the race in 5th place and spent most of the 24 hours running in either
5th or 6th place among the 12 GTP class entries. A total of 61 cars across all classes
started the race.

The car performed flawlessly throughout this classic event, and the JDC-Miller drivers
brought it home without a scratch—a remarkable feat given the heavy traffic they
navigated each lap. Driver Gianmaria Bruni led the team with 562 overtakes during the
238 laps he drove, while Tijmen van der Helm closely followed with 404 overtakes in the
198 laps he completed.

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

“I am extremely proud of everyone on the team for the incredible effort that went into our
6th place finish at the Rolex 12 Hours of Daytona. It was one of those events where
there was a lot going on and everyone pulled together and got it done. Tijmen worked
closely with Gimmi and got Bryce and Pascal well-versed in how to race this car. They
kept the car damage free which isn’t easy to do at Daytona. All the guys on the pit-box
worked together to deal with the low ambient temperatures to find solutions and
maximize what we could get out of the car. Our pit stops were very good both day and
night. Overall, an excellent start to the 2025 season and I’m really looking forward to
Sebring and the rest of the season.”

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

“First of all, I’m very happy with a P6 finish in the race for JDC-Miller MotorSports. The
boys worked very, very hard. We had an issue with brake temperature from the start of
the race, that was tough to resolve. We were not able to put the proper temperature into
them, and then keep the temperature for the whole stint. This changed our entire race
strategy. As the day got warmer, our car balance was perfect. We were very competitive
late in the race and had a good potential to be in the top three or four. I am looking
forward to Sebring. I’m very happy to be here in IMSA with JDC-Miller MotorSports.”

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

“A long 24 hours. We had some problems in the beginning with the brakes which we
tried to work around, but couldn’t really do much about. I think we did quite a good job.
There were some minor mistakes, what happens normally in a 24 hour race. I think we
deserved a bit better place than 6th based on everyone’s performance. 
Now we work
on what we have learned and make Sebring as good as possible.”

Pascal Wehrlein, Driver, No. 85 JDC-Miller MotorSports Porsche 963

“First of all, thanks to everyone involved for this opportunity. It was a long, 24-hour race,
a lot of fun, and a lot of driving. Each time I was in the car, it improved. Racing at night
is pretty cool and something I had not done before. I had a lot of good fights and at the
end we finished in P6. The car was reliable, which was great. Only a couple of issues
which I think hurt a bit of our performance, but nevertheless, for me, it was a great
experience. I want to thank everyone on the team for this opportunity. It was great.“

Bryce Aron, Driver, No. 85 JDC-Miller MotorSports Porsche 963

“I liked this a lot. This was many new experiences for me. I want to thank everyone at
JDC-Miller. It’s been an awesome time getting up to speed in the GTP car and for the
first time doing an endurance race and racing at night. Really enjoyed the challenge
and the race. A very special experience. Thanks to the team and my teammates for all
their help in making it so special. Hope to do it again in the future.”

JDC-Miller MotorSports Porsche 963 Qualifies 5th for the 2025 Rolex 24 Hours of Daytona

Katie Church on January 23, 2025

SAVAGE, Minn. (January 23, 2025). JDC-Miller MotorSports driver Gianmaria Bruni
qualified the JDC-Miller MotorSports Porsche 963 GTP from the 5th position for the 63rd
running of the Rolex 24 Hours of Daytona.

It was a very challenging qualifying session for the Italian driver due to very brisk and
blustery 49° F (9°C) weather conditions and the short 15 minute qualifying session. The
session was further shortened by a red flag just as the tires on Bruni’s No. 85 Porsche
were coming up to temperature. When the session resumed, Bruni skillfully used just
two laps to bring his tires up to tempersture and used his remaining single lap to set the
5th place time, which was just .479 seconds off the pole position.

With qualifying behind them, the confident team shifts its focus to final preparations for
the 24 hour race. Bruni will be joined by Dutch driver Tijmen van der Helm, German
Pascal Wehrlein, and American Bryce Aron.

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

“We would have loved to have a little more time in the session as things were really
coming together to put up a really good laptime when the red flag came out. It is a bit
frustrating to spend a lot of the session trying to get temperature into the tires. We are
really happy with P5 but had a few more spots in our sights the whole session. Gimmi
was outstanding at getting the most possible from his cold tires. We think this starting
position reflects how competitive we are currently and will be in the race.”

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

It was very cold! I think we had a good qualifying. We had to do the best we could in
short time we had after the red flag. The team did a really, really, good job to prepare
the car. I think it was a good lap, very close to the top four cars. We are ready now for
the important part – the race on Saturday and especially Sunday.

I’m really happy to to be racing in America with JDC-Miller MotorSports and can’t wait to
start this race and to race all season with this team.”
