Our philosophy was and still is, to have sportive race were small and big teams enjoy racing. The international atmosphere added a lot to the sportive character as well as the mix of amateurs, semi-professional and professional teams.

In order to keep a healthy mix of cars and teams, we have made some minor changes and added two new classes; Class A3T (turbo petrol engine cars up to 2500cc) and Class GT4 (which suits all GT4 cars).

Main changes classes:

– Class GT4 added separate class for GT4 cars

– Class A3T added, additional class for turbo petrol engine cars up to 2500cc

– Petrol cars 2000-3000cc combined into class A4

– Minimum reference time for class SP2-GT3A changed to increase competition and to bring the performance in line with class A6

– Minimum weight Porsche GT3 cup car decreased to 1150kg to increase competition

– Minimum reference time added to class D1 (Diesel engine) to balance performance

– Small changes to for Silhouette cars, to increase competition
