I do not understand why people are using 100% for spring and damper settings in the thrustmaster control panel. It is my understanding these two settings should really be at 0% .
The spring setting is forcing the wheel back to the middle, higher the setting higher the force being used, which is fine when you going in a straight line but not for corners because the force is trying to centre the wheel. Damping is putting a force on how hard it is to turn your wheel, to me that should be left to the ffb.
No those settings MUST NOT BE AT 0%. Thoses forces are totally misunderstood. Read the doc :

The spring force doesn't put your wheel in center : the "spring" it's just an image (related to cars like damping) to explain that LIKE a spring, the more you turn the wheel, the more you have a force, so it's only mean that it's a force related to your wheel position (like damper, which is related to position and speed of the wheel). Spring and damper are called "dynamic forces" by Thrustmaster (TM) because they depend of the wheel position/acceleration, opposed to constant and periodic forces (Fanatec call them "force" and "shock"), called "static forces" by TM, which are not related to your wheel position. As stated by TM, you can apply a negative spring force who push away the wheel from the center position ! Damping force is like a car damper, it play the role of applying some (simulated) friction and spring-mass effect (add rebound).
So game developper have access to 4 kind of force type, 2 "static" and 2 "dynamics", then they choose if they wanna use all of them or only some. As sated in the Fanatec wheel manual "Not every game uses all types of effects and some games even use only one type to create all different feelings.".
If the developpers havent' use those kind of forces, obviously you can apply 0% or 100%, it doesn't change nothing ! But if the developpers use those kind of forces and if you turn them to 0%, those forces "components" are not applied, and you have a far less realistic FFB. For the damper force, if the developper use this force "component", putting at 0% give you a more detailled but rought effect, at 100% a less detailed but a softer effect. So, like other FFB parameters, you choose what you prefer, 0%, 100% or 58% !
Most of the game doesn't use "dynamic force" and prefer using the "statics" one, and if they need a more "dynamic" FFB, they include this in their FFB algorithm and apply tyo the constant force. Only a developer choice. And, once again, if they haven't use those kind of force, you can set them to any value, it doesn't change nothing.
ACC doesn't use those component, Fanatec recommend to use 100% spring and 100% damper but state that those force are not used, so no need to put their values at 0%.

As a rule, avoid stupidly repeat advice of people without any verification ! And consider 4 things. First, people giving advices are generally (95%) and sadly the less skilled. Two, verify what it's said by yourself instead of repeating what you've read (it apply on every subject, not only tech and racing game, with twitter, those kind of behaviour are the cancer of the society repeating lies and stupidity). Three, if the hardware manufacturer give the option to modify thoses value (and use them as preset on fanatec), there's a good reason. And four giving a static force which oblige your wheel to go to center will be the most stupid thing to add to a wheel, and every model and manufacturer provide a "spring" force, meaning there're not stupid !
NB : for TM wheels, if you modify the force components in your driver panel, you have to restart your game, if not, the settings are not applied (only for global force intensity)
