It would help if you give some context/background such as your experience w AC and which car and track and existing hardware and setup.
Here is my force feedback setup in CM, using T-300rs. I think the control panel level was 100% on all, (not sure about damping). Take it with a grain of salt, I've only accumulated less than 6 days total. My favorite tracks are Norschleife, Laguna Seca and Mt. Akina. Still learning to drift but can do donuts on Skidpad a bit. I think my setup is alright. If I remember correctly increasing the min. force to 5% help a lot when I was looking for the setup. Good luck.
