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.

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.”

Chris Miller and Mikey Taylor kept their perfect 2024 season intact in the Touring Car (TCR) portion of the Michelin Pilot Challenge by following the same recipe of success.
As he did in the first two races this year, Miller put the No. 17 Unitronic/JDC-Miller MotorSports Audi RS3 LMS TCR in contention at WeatherTech Raceway, then Taylor powered the car into the lead and on to victory lane.
Taylor passed a pair of Bryan Herta Autosport with Curb-Agajanian Hyundais in the final 21 minutes of the two-hour race to secure the third win in as many outings this season for the No. 17 Audi. It’s been a rewarding beginning to 2024 for the JDC-Miller team after a shot at winning the TCR championship slipped away in the 2023 finale at Michelin Raceway Road Atlanta.
“We’re focused on winning this championship after it got away from us in Atlanta last year,” Taylor said.
Miller started second in TCR but a miscue behind a GS car during his stint dropped him to fifth place when he turned the No. 17 over to Taylor on a pit stop. Taylor trailed leader Mason Filippi in the No. 98 BHA Hyundai Elantra N TCR by eight seconds with 45 minutes remaining but chipped away the deficit quickly.
Taylor shoved his way past Robert Wickens in the No. 33 BHA Hyundai through the Andretti Hairpin with 21 minutes to go. Two laps later, he followed a pair of GS cars past Filippi in the same spot to grab the lead and went on to win by 1.254 seconds.
“I don’t think we had crazy outright speed, but on old tires, which is what this track is known for, we were OK,” Taylor said. “It was a couple tough passes. The GS guys helped me out a little bit, making some holes, and we took what we could.
“It feels great, feels great,” Taylor added. “I had my mind on my wedding next week a little bit, but it feels good to be here. Great points for the team and just happy for everyone in the program.”
The win was the ninth for Taylor in Michelin Pilot Challenge competition and the eighth for Miller. Meanwhile, Filippi and co-driver Mark Wilkins, trying to repeat as the WeatherTech Raceway TCR winners, felt that second place was the best they could do on this day.
“I think we did the best we could today,” Wilkins said. “We can’t compete with that car with the pace right now that they can run, so for us, we were just trying to make as few mistakes as possible. We ran really a perfect day in my opinion, so second is a win for us today.”
Saturday’s race broadcast will air at 1 p.m. ET Saturday, May 18 on CNBC. Both classes of the Michelin Pilot Challenge return to action June 6-8 at the O’Reilly Auto Parts Four Hours of Mid-Ohio.
Savage, Minnesota (May 6, 2024). JDC-Miller MotorSports is returning to
WeatherTech Raceway Laguna Seca, where they debuted their Porsche 963 GTP
campaign one year ago. Last year, the JDC-Miller MotorSports team brought their two
week-old 963 to WeatherTech Raceway Laguna Seca to shake down the car in a most
public way. Prior to Practice 1, the team had only made a lap around their parking lot
with the new car. Typically, in motorsports, this would be considered very risky, akin to
learning to swim by diving into the deep end of the pool; the team, however, had
confidence in their abilities and the abilities of their partners in this project.
With the help of their technical partners, Porsche Motorsport NA, Multimatic, Bosch, and
WAE Technologies, the team powered through the concise timeframe and soldiered on
to finish 7th of the 8 GTP cars and only 23 seconds behind the race winner. Gaining that
race experience set the stage for upcoming solid performances for the remainder of the
season.
For the 2024 Motul Course de Monterey Powered by Hyundai N, the team returns
knowing the car and how it responds to changes. They now have experience with the
GTP-class Michelin tires and are well-rehearsed on pit stops and driver changes.
Richard Westbrook returns to one of his favorite tracks with three wins at WeatherTech
Raceway Laguna Seca under his belt. For Tijmen van der Helm, the tracks, with the
exception of Detroit, will no longer be new to him as he returns to each of them behind
his Porsche 963 GTP wheel.
The team is confidently looking forward to this year’s race.
Quotes:
John Church, Managing Partner, No. 85 JDC-Miller MotorSports Porsche 963
“Last year, we decided to take an aggressive approach to rolling out the new car. Early
in the year, we knew we would not have the Porsche for Sebring, so our attention
shifted to Laguna Seca. The Porsche team in Weissach worked through many
challenges to get the car together and shipped, but it was clear that the timing would be
very tight. We could have waited to debut the car at Watkins Glen a month later, but I
felt strongly that we needed to start gaining experience and knowledge of this complex
machine as soon as possible. The entire JDC-Miller MotorSports crew was fully
onboard with this approach, as we were all excited to get our Porsche 963 program
underway. Through herculean efforts and many long nights by many people, we
performed very well at Laguna Seca. What we learned that weekend set us up for 4th
place finishes at the next two races, Watkins Glen and CTMP. While incredibly stressful,
we learned much about the Porsche 963 and the GTP program. Knowledge and race
experience that benefits us today. I am really looking forward to this weekend.”
Ryan Perera, Systems Engineer, No. 85 JDC-Miller MotorSports Porsche 963
“Looking back at this weekend one year ago, we went to WeatherTech Raceway Laguna
Seca, knowing our partners would help us get the car ready for the race.
There was a massive outpouring of support from our technical partners, Porsche,
Multimatic, Bosch, and WAE, who were all as excited to see this car on the track as we
were. At times, there were a dozen knowledgeable and skilled people in our garage
looking to make valuable changes and updates to the car. People were queuing up to
plug their laptops into the vehicle. It quickly became overwhelming as we had not
completely thought through how we needed to manage this process. The stress level
rose until John (Managing Partner John Church) put a stop to making changes and
directed everyone to get focused on readying the car for the race. That allowed us to
focus on fixing the issues you inevitably have with all new cars and establish a
performance baseline we are building on to this day.
After that experience, we established a process to work with our technical partners and
maximize their valuable expertise in an organized manner.
As stressful as it was, I feel a great deal of pride when looking back on that weekend.
We went to Laguna Seca to shakedown a brand-new car unlike anything we had raced
before and finished on the lead lap. Quite an accomplishment!
Josh Kerrigan, Car Chief, No. 85 JDC-Miller MotorSports Porsche 963
“We spent a couple of weeks at Porsche in Weissach learning about the car and its
systems as well as how everything went together. Our challenge for Laguna Seca was
simply time. We didn’t have any. With a new car, a ton of electrical and other
components must be installed. The punch list is always very long, but even longer with
all the added systems of a GTP car. Unfortunately, we had the car in our shop for less
than a week before the truck headed west. The drivers came and were fitted to the car.
We went through the start-up process just one time before the car had to leave. When
the trailer was opened at Laguna Seca, there was a tremendous amount of work yet to
do to make the car ready for the race. Pit stops under GTP rules had to be worked out
and practiced, as well as driver changes. Every night was a very long night.
The payoff for all the hard work came on race day. When Tijmen took the checker on
the lead lap, all I could think of was, “Wow, we did it!”

Drivers of the first true customer car in IMSA’s new GTP class, JDC-Miller Motorsports’ Porsche 963, say they achieved their aims on debut at Laguna Seca on Sunday.
By Charles Bradley and Mandy Curi
Veteran sportscar star Mike Rockenfeller and his teenaged team-mate Tijmen van der Helm steered the 963 to seventh in the IMSA SportsCar Championship’s fourth round, having been forced to miss the opening three races due to supply chain issues that delayed the build of Porsche’s customer chassis.
Rockenfeller finished the race directly behind the Daytona 24 Hours-winning Meyer Shank Racing Acura and the first of the BMW Hybrid V8s in the 102-lap race. The team only received its car shortly before the Laguna race weekend, following a shakedown at Porsche Motorsport’s Weissach test track by factory driver Matt Campbell.
“For the very first time in a car like this, I think we did pretty good,” Rockenfeller told Motorsport.com. “The car was tricky to drive, everybody was struggling with grip, but we showed up with zero experience!
“We know we are missing ultimate pace and, for me, that’s a balance issue and understanding the braking – I didn’t feel in control 100 percent. P7 is never what you want, you want to fight for the podium, but let’s be honest, we finished the race with no scratches on the car and we get into a lot of fights out there with our opponents.
“It seemed that we struggled on the new tire at the start of the stint, and towards the end I could manage the car better, even though it wasn’t easy with the brake bias. There are like 500 adjustments in these cars and you need a half-decent routine!
“But, all in all, I think we did a half-decent race, and we can be proud as JDC. We’re only a small team, so it’s not like we go testing, we have to learn this car race by race.”

His co-driver van der Helm, who was making his first start at the top level of sportscar racing after piloting LMP2 machinery in the European Le Mans Series, both qualified and started the car before handing over to Rockenfeller.
“It went better than expected,” said van der Helm. “So much to learn, so much still to learn. But I think Mike and I did a pretty good job along with the team, and I think we should be happy about the job we did this weekend and I think we can look forward to all the other races.
“This was a learning experience, a kind of practice race, and I think it went well enough to look forward to Watkins Glen now. Our goal here was simply to finish, and just see where we finished, so I think we should be happy with P7.
“Now we can spend some time behind the laptop, and work on getting our pace towards the other cars.”
