Basically don't expect the wheel to do all the work, Try putting your settings...
FFB-7
Power Assistant's-Off

And what you wanna do is have SMALL corrections I find at times the front end has crazy grip other times I can't get grip (real pain in the a$$) So what you should really do is get a decent setup which you know works for wheel drivers then watching real life cockpit views and even watching some nerd who recorded themselves driving with the G27 and you see the major difference what I'm trying to say here is treat it like a video game not as if it was real life, Know what I mean? Another thing at first when learning try to have at least one hand on the wheel at all times. And when you get those angles high angles you gotta bring back the wheel yourself, slowly bring it back and bam you should be drifting it no longer then a week. I did, And only had 8 hours in. Now I probably have close to a month and I still suck... Once I get more consistent then its game over BABY!
