in my '84 polo all three pedals feel as stiff as a non servo assited brake should!!
For a sim the throttle wouldnt need any ffb and the clutch im in two minds about... because some older cars i've driven you can feel very small effects through it but with modern cars i dont feel anything
the brake however would be good to have some ffb... for example when braking hard feeling the brakes fade would be awesome and make the sim a lot scarier. But also i think ffb would make it feel so much more like a real brake pedal simply because in a real car its not a spring that stops you pushing further, its the pads on the discs and the two have a vastly different feel to them.
So i dont think ffb in the sense of a wheel's ffb is a good idea as there isnt much to fb but a different way of providing the resistance is needed, possibly through a ffb-esque system
Having said all of that people with modern servo assited brakes shouldnt complain about lack of feel because those brakes arent exactly much better!! lol Go and drive a real car with no power steering, no servo brakes and no fuel injection just ordinary carbs!!
Yeah my Polo!!
