Having won at Monza, Verstappen headed to Germany to earn the required DMSB Permit Nordschleife that would allow him to race GT3 machinery around the ‘Green Hell’ and compete for overall victory.
Getting the Grade A permit included an intensive crash course: theory lessons and an e-learning module, followed by instructional laps around the circuit and then race participation in a restricted Porsche Cayman GT4 CS during NLS7 alongside sim-racing team-mate Chris Lulham.
With the permit secured, Verstappen then stepped into the Emil Frey Racing Ferrari 296 GT3 later that month for another NLS round and promptly won, having taken pole by 3sec.
