Laurin Heinrich surged past Earl Bamber in the closing moments to deliver a dramatic overall victory for JDC-Miller Motorsports at WeatherTech Raceway Laguna Seca, securing the team’s first IMSA win since 2021 and its maiden GTP triumph at the circuit.

Sharing the No. 5 Porsche 963 with Tijmen van der Helm, Heinrich made his decisive move on the final lap. Using lapped traffic to his advantage, the 24-year-old closed rapidly on Bamber’s No. 31 Whelen Cadillac and timed his run perfectly, diving through the final corners to complete a bold, race-winning pass.

The result capped a race defined by early chaos, evolving strategy, and late-race drama across all classes.

Trouble struck immediately at the start when Tom Blomqvist was sent into the wall at Turn 3 in the No. 60 Meyer Shank Racing Acura, disrupting the GTP field on the opening lap. Ross Gunn capitalized on the incident, slicing through the disorder to climb into fifth in the No. 23 Heart of Racing Aston Martin Valkyrie.

At the front, Louis Deletraz controlled the early stages in the No. 40 Wayne Taylor Racing Cadillac, but the team’s momentum quickly unraveled. Sister car driver Filipe Albuquerque suffered a puncture following contact, sending the No. 10 to the garage. Although it returned laps down, the car was later retired.

The race began to shift when Jack Aitken made a decisive move on Deletraz to take the lead in the No. 31 Cadillac, signaling a turning point as strategy came into play.

Pit cycles proved critical just past halfway, with GTD teams among the first to dive in for service and driver changes with over two hours remaining. Shortly after, a major contender fell out in dramatic fashion. The pole-sitting No. 34 AF Corse Ferrari, which had led early with Patrese at the wheel, encountered trouble after handing over to Albert Costa—slowing on track before catching fire in pit lane and retiring.

More adversity followed as the No. 65 Mustang of Christopher Mies received a drive-through penalty for contact with the No. 7 Penske Porsche, costing valuable track position and forcing the team to reset its strategy.

A pivotal moment came when a full-course yellow was triggered after Michael Bell stopped at Turn 2 in his No. 13 Corvette. The caution bunched the field and reset the race heading into its final phase. On the restart, Felipe Nasr led ahead of Renger van der Zande in the No. 93 Meyer Shank Racing Acura, with teams now fully focused on energy management and the timing of their final stops.

As the closing stages unfolded, intensity ramped up across every class. In GTD Pro, Alexander Sims (No. 3 Pratt Miller Corvette), Ben Barnicoat (No. 14 Vasser Sullivan Lexus), and Connor De Phillippi (No. 1 Paul Miller Racing BMW) battled closely while balancing pace with fuel strategy. Several teams gambled on stretching their stints in hopes of another caution, but most were ultimately forced to pit under green, reshuffling the order once again.

Despite its earlier setback, the No. 65 crew rebounded with a clean, efficient run to the finish, as Frédéric Vervisch and Christopher Mies claimed victory in GTD Pro. In GTD, Trent Hindman and Danny Formal delivered another win for the No. 45 Wayne Taylor Racing Lamborghini, capitalizing on strong execution in the pits and disciplined fuel management.

Out front, however, the spotlight belonged to Heinrich. His decisive final-lap overtake capped a relentless charge and returned JDC-Miller Motorsports to victory lane in spectacular fashion.

“Yeah, it seems to work for me at this place,” said Heinrich. “I love it, to be honest. Every time I come here in the morning and see this track, I feel something special. And today, it’s incredible. The team gave Tijmen and me an extremely strong, well-balanced car. I think our strength was on tires, which we could really make use of in the last four or five laps. The strategy also worked great. For sure, it was not a perfect race for those who watched closely and saw my little excursion in Turn 2, but that’s part of it. We were pushing flat out—that was all we had. Mistakes happen, but I’m so proud of the whole team. To be given this chance to join late and gain experience, and now finally have all of that work pay off, is incredible.”

“This is an incredible day for the whole team,” said team owner John Church. “All the effort that’s gone in over the last four years—we started here not really knowing what we were doing with this car and have slowly built and picked up the pace. It’s been great to have Laurin come in, help guide us, and provide speed as well. What a day—just incredible.”

The victory also marked a milestone moment, as JDC-Miller Motorsports became the first privateer to win in IMSA’s GTP class. It is only the second such win in the broader GTP/Hypercar era across IMSA and the WEC, following AF Corse’s No. 83 triumph at Le Mans last year. It also marked Tijmen van der Helm’s first career IMSA victory—fittingly coming at the same track where he helped launch the team’s Porsche program in 2023.

The IMSA WeatherTech SportsCar Championship now shifts away from its West Coast swing and returns to the Midwest, with the next round set for the streets of Detroit in three weeks. The 100-minute event will also mark the final shared weekend with IndyCar this season.
