I have been trying for a few hours to get Dirt 4 to feel a little bit more like Dirt Rally in terms of FFB. Dirt 4 in comparison feels rather muted in terms of feedback. Well i have been messing around and may have found a way to increase the feeling of FFB in the game.
**PLEASE NOTE : I have no idea if this is ok to use online so use at your own risk **
Go to where Dirt4 is installed : steam/steamapps/common/dirt4/input/devices
You will see a file called "device_defines" - Open this with "Notepad"
In this file you will see a list of wheels and there supposed ffb values. As seen here :

Find the particular wheel you use, so in my case the "tm_t300_rs"
You will see listed to the right "ffb_friction" & "ffb_force" - Try increasing these values. This is what mine is set to :

And these are my ingame settings (subject to change), im still tweaking :

For me it has definately improved the FFB in game and made everything a bit stronger, its not quite near the level of Dirt Rally but its a start at least.
Hopefully it'll give you guys a heads up and something to work on and hopefully improve the feeling for you.
Remember, i havent tested this online so i have no idea if its ok to use for online racing.....
