I have been driving the Stock Car and all the other releases since day 1. I enjoy driving all of them but I have come to the realization that in the stock car my performance is far inferior to what I can usually accomplish even in the other series in GSC as well as every other sim I own. It seems to me as if I am just stuck and I am not getting any better. Driving against the AI I had to reduce the strength to 90% in order to race against them without being left behind by the entire field. And I still don't win, I just manage to stay with the group. In Formula Reiza, F3 and the Vintage it's a totally different story. I race against them at 120% and while I still don't win, I am not regularly left behind. I joined the league and to my dismay there too I fell to the very bottom of the field in practice and qualification (not quite the bottom but certainly the lower 1/4). The reason seems to be that I am simply not getting better. My times at various tracks remain static and there are barriers I am unable to break. With the other cars and in rFactor, GTR2, etc. I am usually in the top half of the field if not racing for the podium. So far, my best theory is that I am overdriving the cars out of frustration, but I'd like to know what others think. Do these cars require a technique I am unaware of? I am usually a very regular racer. The reason I am often able to achieve good results in leagues and other races is not so much my speed but the ability to lap regularly. I am often best when I have no drivers around and I can concentrate on the track. I'd like to think I am a smooth driver when I get in the zone, but if frustrated I can quickly lose it and start making mistakes.
