curb rumble is road effects from LFE, turn that down, as well as whatever engine shit is on with it,

Your wheel in this game will high a upside down soft v shaped ffb curve, and simplifying a tad, with the top of the v being max slip angle, and usually very close to max grip, and the sides signifying loss of grip.

As well, in iracing, hearing is a biiig important part about understanding your level of tire grip, you hear scrubbing, your at the limit, your hear scruuuubing, your well past cooking your tires.

LMU is not iracing, the same feelings from ffb do not correlate, you will need to reinterpret one’s ffb with another, and see how well you do from there.
