Although I’m on PS5 and wheel dampener and enhanced understeer is meant to only effect wheel users. This was not the case last year. As shown in the link. https://forums.codemasters.com/topic/86940-f1®-2021-barrys-basics-setting-up-for-controller-play/
If it helps I find wheel rotation off 320-340 gives that little extra bit off responsiveness in the corners whilst still being able to keep inputs smooth. Without having to add any steering linearity or saturation.
lastly short rise extension sticks actually work really well just as longs your not to heavy handed as that will cause them to ping off.
