Good to see you making progress Will. I use the FFB settings / advice from that RBR thread and it feels rather good to me. Driving these Rally cars is very different though, nothing like the usual Circuit style driving, and not easy either. In these cars, you just have to get used to how hard you can push and throw it around, and even then it depends on the specific car, track surface, and weather. Make sure you work your way through the Rally School though, the lessons are invaluable.
Now, to get the practice and experience, head over to the RBR Club events and join in. Don't worry if you crash a lot, we all do it regularly, but we still have fun comparing / discussing how we mangled the car, went over a cliff, slammed a tree, barrel rolled it, etc.
We would love to see more guys from the US join us, Aaron is working hard to get the RBR Club humming, but he has been driving alone in the US timezone. He'd love some company in these Rally's and on TeamSpeak.
