No. 85 Porsche grabs GTD PRO win at Laguna Seca with last‑lap pass
- Laurin Heinrich and Tijmen van der Helm won IMSA’s Monterey race on May 3 in JDC-Miller’s No. 5 Porsche 963 after a last-lap pass. - Heinrich dived past Earl Bamber’s No. 31 Cadillac in Turn 5 and won by 0.758 seconds, ending JDC-Miller’s five-year overall drought. - The result matters beyond one race — JDC-Miller became the first privateer team to win in IMSA’s GTP era.
Prototype racing is the top of IMSA’s ladder — factory budgets, hybrid systems, and usually the same handful of giants fighting for wins. That is why Laguna Seca landed so hard. On Sunday, May 3, JDC-Miller MotorSports beat the factory heavyweights with its No. 5 Porsche 963, and Laurin Heinrich finished the job with a last-lap pass that turned a good run into a landmark win. It was not a GTD PRO result at all. It was the overall GTP victory — and a pretty historic one at that. (imsa.com) ### What actually happened? For most of the 2-hour, 40-minute Monterey SportsCar Championship, Cadillac looked like the class of the field. Earl Bamber and Jack Aitken had the No. 31 Action Express Cadillac in position to win, but Heinrich closed late, attacked on the final lap, and slipped by Bamber in Turn 5. The margin at the flag was 0.758 seconds after 119 laps. (sportscar365.com) ### Why is that such a big deal? Because JDC-Miller is not a full works operation. In IMSA’s GTP class, the big story since the rules reset in 2023 has been factory muscle — Porsche Penske, Cadillac, BMW, Acura. JDC-Miller runs as a privateer customer team, and this win(sportscar365.com)t built the category to showcase themselves. (racing.porsche.com) ### Who were the drivers? Tijmen van der Helm handled the opening part of the race and kept the No. 5 Porsche in striking distance. Heinrich, a Porsche factory driver better known to a lot of fans for GT racing, took over for the closing stint and did the hard part — tire management, traffic, then t(racing.porsche.com)h, and Heinrich had the pace to cash it in. (newsroom.porsche.com) ### Why did the pass come so late? Laguna Seca is brutal for closing a move cleanly. Track position matters, tire life matters, and dirty air can trap a faster car behind a slightly slower one. Heinrich spent the closing laps pressuring Bamb(newsroom.porsche.com)car width, and you go. (sportscar365.com) ### Was this just a fluke? Not really. Surprise result, yes. Fluke, no. Strategy played a huge role across the race, and JDC-Miller executed cleanly enough to stay in touch while others controlled the early phases. Once Heinrich had a shot, the Porsche had the speed to make it real. You do not luck into 119 laps of contention in GTP. (imsa.com) ### What changed for JDC-Miller? The team had been waiting a long time for a breakthrough. This was JDC-Miller’s first overall IMSA win since Watkins Glen in 2018, and multiple reports also framed it as the team’s first victory since 2021 in broader class terms. Either way, the drought was the point — this was a small team finally converting years of persistence into a headline result. (frontstretch.com) ### What does it mean for Porsche? It is a reminder that Porsche’s customer-racing model still has teeth at the very top. Porsche Penske did not win the race, but a customer 963 still put the brand in victory lane. That matters because it shows the car can win outside the factory bubble — and that makes the whole program look deeper, not just richer. (newsroom.porsche.com) ### Bottom line The story at Laguna Seca was not a GT class photo finish. It was a privateer Porsche beating the prototypes that were supposed to own this era. Heinrich’s last-lap move made it dramatic — but the bigger point is that JDC-Miller just proved the GTP order is not as locked down as it looked a week ago.
