The physics are very much to blame for some of PC2's issues as well as the FFB. The black hole curbs that pull you in so strongly that you ridiculously over correct the wheel to get out of them before being pulled into the grass is ridiculous at times and has nothing to do with FFB. Cars feeling as though they pivot from the middle of the car instead of the front wheels is another issue that FFB just can't correct. And you're correct, the diff is weird. On each car I drive I usually have to open the diff fully, and then add in whatever it needs, be it power, coast or preload (or ratios) to get it feeling right. More times than not, the power being as close to fully open, 90 degrees, can make a car feel better. This also helps me in AMS2 as well.
You did a good job on the FFB though, I think there's just things that are out of reach of the FFB file going on.
