If you play on XBOX ONE with the maxrace adapter to run your g27 wheel you need to grab the firmware update.
It makes the steering much more real and less twitchy, just install and put deadzone to 0.
It still wont be as good as G27 on pc, but is really good (I have the game for both)
you still don't really get proper ffb but you get the bumps and stuff.
They have the firmware here

I have no affiliation with them and actually recommend purchasing a proper xbox wheel. But if you already have one this makes it much better
