Part of this controller being so uncomfortable is that the steering wheel is very hard to turn and is slippery. I took my controller apart to see if I could "loosen" the springs so it's easier to turn but it did not look possible once I saw the mechanics of it inside! I'm now thinking if there is a good way to rough up or make the steering wheel rubbery so you can get a good grip on it.
Also when I turn it, my car is full left or full right halfway through the turn so it is very sensitive. Is there any way to make it so it uses the full length of the turn, like an ATV adjustment?
