Even if we are using ONLY the FFB wheel as the basis of comparison then each would have to have the same rotation and
the the same setup for the car we are driving.
...and the same clothes, the same seat, the same hi-fi. Don't forget the same room with the same furniture. Also the same temperature and humidity! Actually, we should also be the of the same height, have the same mentality, look the same and in general - just be the same!
I asked him about the feeling/immersion and he found them very good/strong. Also didn't find 9:1 steering ratio too fast or slow. He spend two days here and drove at least 8 hours so I think future looks very promising for rF2!
