It really depends. For some YES, for some NOT. For me YES!
When you never drove with a Force Feedback Steering wheel, it will take many many hours of getting use to, then you should be able to match your speed that you made with a PAD, or even better.
For me it made me faster, because wheel is more accurate and smoother to Turn, brake, accelerate, etc etc.. as well you are able to feel the car with the feedback if car is or is about to over steer, under steer, etc etc.. a decent wheel adds so much to simulation and fun factor with a racing game, both for arcade games and sim games.
I would say give it a go..
IF you wanna buy a wheel, do not make any mistakes. Only 2 wheel companies you should buy and consider is LOGITECH or FANATEC . Never buy a wheel other then those two companies, some other cheap 100 dollar wheels are crap and will not make you faster and you will hate them.
