Howard Casto actually finished the FFB mod, however, he has not released it yet, as he has been sick, and also wants to add more content.
If you look through the thread, you can find data for FXT, which I believe adds rumble on Xinput wheels (don't quote me on that, not entirely sure), a couple of other minor tweaks, and he started replacing the textures with higher res versions when he just vanished off the forum.
