At the eighth race of the Nürburgring Langstrecken-Serie (NLS), the 46th DMV Münsterlandpokal, the two Zimmermann Porsches fielded by Mathol Racing once again took to the grid. Both cars finished and placed in the top 30 overall. There was a classification group win, a class win and another podium with the fastest race lap. Mathol team boss Matthias Holle: "That was a strong performance by the team. In terms of speed and reliability, we showed a top performance." The external conditions in the Eifel region were not easy. During the morning qualifying session, the track was initially wet and slippery. Towards the end, conditions improved. At the race start, conditions were better but still not ideal.
The Zimmermann Porsche 718 Cayman S competed as usual in the VT3 class. This time it was driven by Argentineans Marcos Adolfo Vazquez and Nicolas Martin Varrone as well as German Jan Fittje. In practice, the trio took pole position in class and 47th overall out of nearly 100 cars. In the race, the Mathol Porsche took a commanding lead in the class right from the start. At the finish line, in addition to the class win, it also took the classification group victory for the first time this season. The trio managed to make up for the 120 seconds longer pit stop time compared to the competition on the race track.
Arne Hoffmeister and Frenchman Dorian Boccolacci again piloted the Zimmermann Porsche 911 GT3 Cup, which competes in the "Porsche Endurance Trophy Nürburgring" one-make cup. In practice, the duo drove to third place in class and 15th overall. The Zimmermann duo was in the fight for the class win from the very beginning. Starting driver Boccolacci handed over the Mathol Porsche as leader to Hoffmeister, who was able to hold the top position until he handed over to the Frenchman again. But a little later, the regulations at the Nürburgring struck mercilessly. Because the Mathol car had rolled into a Code 60 zone too quickly, the team was given a stop-and-go penalty lasting just under 5 minutes. This put an end to the dream of a first victory. At the finish line, the team finished third in class, 4:11.604 minutes behind the class leader, and 10th overall. Team boss Holle: "It couldn't have been better for us. Without the penalty, we would have been fighting for the win and had a good chance."
