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.

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.”
