Not really the same topic but I don't want to open a new thread.

I use a G25 (100/30% FFB) and it's really nice for the XFG but everything above it feels very heavy and almost impossible to countersteer (using the realistic wheel turn values). So I decided to make scripts for each car changing the FFB to a more realistic value but I have no experience with real cars. I could lower the FFB to say 15-20% and just raise it to 30% for XFG and 25% for XRG and they'd be pretty alike but I don't really want to make all the same. So the question is: what force value do you recommend for each car if the main directive is making them feel as real as possible?
