This adjustment aims to create a more seamless transition for participants and fans alike, ensuring that the excitement of competitive racing remains consistent throughout the year. By synchronizing the schedules, we hope to enhance the overall experience and engagement for everyone involved in the championship. we are adding BRNO - BRANDS HATCH - DONINGTON PARK & MONZA WITH A DIFFERENT RACE FORMAT THIS WILL BE Practice 1h - Qualify 10m - Race 1: 20m - Race 2: 30m
