Half a decade of very weak fields, the organizers decided to ban GT3 cars and let smaller cars compete for the overall win, in a bid to attract more interest. With 53 cars on the list, they seem to have reached their goal quite successfully. Question is if this set of cars will be attractive for spectators or if the race will become a mere club racing event.
