World Series-Manufacturers Cup 2023-2024 Exhibition Series: I just did a practice session for round 2- Dragon Trail-Seaside Reverse and I see that GR3 cars are being used in this GT2 class practice event? The Global Ranking leaderboard is full of GR3 cars that have set times my GR4 car can't begin to compete with. I tried to enter this practice session with some of the same GR3 cars that have posted times but it says "you are in violation...can't enter...etc. I'm new to all this so, what am I missing? Can you de-tune a GR3 to GR4? How did these guys get these cars in, and will they be able to use them on race day?
