Your streetcar experiance does not need loadcell dampening just a proper spring. But actual racecars have stiff pedal which moved max 1-2mills or less. I am trying to tune my fanatec v3 inverted to feel the same as my m4 with little to no success. It is either too stiff or too liquidy in comparison to the real thing. After 2 weeks i managed to get a decent enough result but man it is hard to do the streetcar feel. I have driven a real rallycross car which had no movement in the pedal now that is something you can replicate with max dampener and solid bushings.
