I've made an app that shows you what your FFB is doing and suggest a gain setting to avoid most of the clipping. The SLS is a little special, since it can generate huge forces, but there's not much detail. I think they have some sort of "powersteering" filter built in, so the cars with power steering are pretty dull.
I'll release the app later today, got some more refinements to do on it.
