Hi guys
New SC2 Pro user here, after fiddling around for about 3 frustrating weeks not getting anywhere and reading about anything i can i finally found some settings im pretty happy with so i thought i share my settings here too.
But first, shout out to @Andrew_WOT, thanks for all your posts, helped me a great deal making progress with my own findings.
My main problem was finding settings that give me enough small details and feedback without getting too strong in corners or getting too edgy to feel what the car is doing at and over the limit.
First i tried different combinations of TD strenght, AC FFB gain and in-car gain to tone the main strenght to a good level.
Turning down TD strenght felt wrong, even tho general strenght was better, i lost dynamic range and details and it just didnt feel right.
In the end i left TD strenght at full power and adjusted AC FFB gain to such a level (only 10%) that the average in-car gain is around 100% to have the widest possible spectrum for in-car gain.
My next problem was to town down spikes and holding forces while not loosing details. That was a bitch and costs me the 3 weeks lol, Granite Devices not really being helpfull here with documentation and explenations what all the filters and settings actually do, how they work, when to use them and even worse how they react to each other.
I would have loved to use RC filter OFF but no matter what other settings i used my wheelbase made metalic clanking noises so it had to be at least on 1.
I also liked RC filter 5 and 7 but both of them lost details in one way or another. I could counteract that somewhat with higher damper/friction/inertia but then i lost details somewhere else and the wheel got sluggish.
After settling on RC filter 1 i tried to just play with damper/friction/inertia but i couldnt get anything good, anything over 10 felt terrible and below i had too much spikes.
Then the static force reduction but same here, forces went down but so did the details, so off it is.
Then thanks to Andrew 
i went down a rabbithole with the Ultra Low Latency Mode when i tried his settings which looked promising first but after testing some different cars and settings it also just felt just wrong (sorry, no offense).
Then i went down another rabbithole with the AC and CSP gyro, the different strengths and the Direct Input Effects. I should note that i never used any gyro with my old Thrustmaster TX, i tested it again with my SC2 just to be sure but went back to no gyro at all in the end because it just distorts the FFB imo.
But this lead me to test the DI effects for themself and turning DI effect Damping from 0% to only 5% finally took the edge of my spikes and gave me the necessary damping without taking details out of it as it happens with normal damping.
Finally something that feels good with all my test cars with only changing in-car gain where im between 72%-115%.
I test with GT86, M235i and 1M stage 3 on the Nordschleife but with my own setups. Also tested the Shutoko S14 because thats a very soft outlier which i play with 115% in-car gain now.
So happy i can finally just play and enjoy that wonderfull wheelbase instead of getting frustrated by terrible FFB. Next game is BeamNG - NOOOOOOO 
Here the settings i use now, maybe its helpfull for someone else who’s not happy:
) screw up the damper implementation and vibrate like crazy when the car is not moving… so I had to had this value to allow to turn the damper off, or reduce the effect.
