We all know that no matter how great LFS is, a computer simulation isn't able to give you the complete experience of racing a real car because of the absence of G-forces for example.

I just came across this: http://www.dignews.com/news.php?story_id=21292

I can't seem to find an official website about it. It's probably not going to be cheap and it's extremely geeky but I do think it sounds interesting.

Now, I'm not insinuating this has been the missing link in simracing (it's not aimed at simracing specifically), and that this will give complete realism, there's a chance it's complete "PS2 style rumble effects" crap, but I'm curious to know how this would feel
