I am 28A and 23B and not once have I worried about what level I am at. I am now taking my favorite 10 cars into practice mode and running laps to adjust for my best tune with the DFGT.
I love driving so much and this is now renewed 10 fold with the DFGT that I dont care if I ever reach "40". I will soon get the Fanatech GT2 and Clubsports.
For me, it's not about the destination, it's all about the ride.
