Works just fine with my Thrustmaster RGT, and it is playable at 50% FFB
The feeling is simply great, I feel the car a lot better, but I find the big bumps somewhat exaggerated and the little ones more or less inexistent, and I can't really feel when I'm running on the kerbs, which would make it so much more realistic, as they're supposed to be felt...
All in all, an excellent mod, and I hope you'll keep up the good work (and the LFS guys will check it out, too, hehe...).
