What are your settings that you recommend for the steering filter with arrow keys/controller? I forgot what mine's set at, but I also have both (Grip) and (Drift) checkmarked in the "Filters" tab (what's the difference between the two, by the way, and do they work when they're both on?).
If you edit your Steer-Left and Steer-Right bindings, you'll notice you can choose a Filter. Among them, there is keyboard(grip) and keyboard(drift). Drift one reponds faster and is more suitable to stunt-style driving, when compared to the grip filter. The Filters tab lets you configure how each of those filters work, and therefore only apply to the filters you've chosen in your steering bindings.
What are your settings at/what would you recommend for the settings? I forgot what mine was, I think it's goes to 15% from 0 MPH up to 60 MPH.
