Thrustmaster t500RS settings for "realistic" or at least believeable FFB

[kai sch.]

Finally reinstalled my copy rbr after years it spend in a box put away in the Garage.
The time I bought it, it was simply to much for me, and I really sucked at it.
With time I learned a bit driving (a lot games come and go....and left me right now with Dirt Rally and AC which I love very much).
And on the forum there is always the comparisson (e.g. Dirt Rally) with a true sim (aka RbR) and so.......
So i remembered my still allmost unused copy RBR and installed it on my PC.
All is well, just have to learn to set up my 3 Monitors, load some mods to enhance perhaps the tracks and cars I can chose from.

But now my concern: I have a Thrustmaster T500RS, getting it to work was no big Problem, but now I ask myself how to setup FFB for that particular wheel, for a "realistic" FFB.
As I have learned some false settings will destroy the realism for sure, and even a nice wheel like the T500 will feel like a toy (learned it the hard way with AC, Dirt Rally and Pcars)

Can you help me out?
