The GT-Classics (GTC) is a series that has set itself the task of bringing historic GT `s from the era of the 80s, 90s and 2000s back to the racetrack to make this “Golden Era” of GT sports for all generations and stakeholders (fans, participants, organizers and partners) to experience again. Thus, former CUP cars as well as ITC, Group 4 and Group 5 cars can compete.
