At the Rowe ADAC 6h Ruhr Cup Race, the fifth round of the Nürburgring Langstrecken-Serie (NLS), Mathol Racing used the Zimmermann-Porsche 718 Cayman S as usual. With good external conditions - dry track and pleasant temperatures - a little more than 150 teams started at the 6h race in the Eifel region.
The successful Zimmermann-Porsche 718 Cayman S in class VT3 (starting number 474) started the 6h race with four pilots. In addition to the Zimmermann established drivers Wolfgang Weber and Alex Fielenbach, Kim Berwanger and Reinhold Renger also took the wheel. In the qualifying session the Zimmermann-Porsche with a lap time of 9.12,772 minutes easily set the best time in its class and was also ahead in the classification group of close-to-production vehicles.
In the race everything went according to plan at first. But at the second pit stop, the mechanics discovered two sheared wheel studs, probably a consequential damage due to contact in the starting phase. After a longer repair break, the Zimmermann-Cayman fought his way back to the top of the class, but this time victory in the classification group was out of reach. The test of the next generation of Zimmermann brake discs, which were tested under racing conditions for the first time, was positive. Weber: "The further developed discs worked precisely, the brake worked well".
Conclusion of team manager Matthias Holle: "A good performance. Unfortunately, this time we were a bit unlucky and missed the victory in the classification group.
