Ok, I got it.
- in-game sliders have to be at the max.
- Centering Spring should be at 100%.
- driver's Overall, Spring and Damper have to be the same.
If you want to modify this, then:
- multiplification of driver's Spring and in-game Strength, and also
multiplification of driver's and in-game Damper have to be the same as
Overall.
- Centering Spring should be the same as in-game Strength.
