IMO, an Alcantara covered steering wheel is nice when on the track. When you have gloves to go with it, they stick to each other nice and you don't lose your handle with the car.... had that setup on my old Civic track car. The bad thing that I hated with an Alcantara covered steering wheel is using it for daily driving. Not because it felt bad or anything, but because when your palms sweat, it ruins the material on the steering wheel and over time the wheel doesn't look at good anymore with 'wear spots' all over it or the material starting to shred up (happenned to me on 2 different Sparco steering wheels).
In an NSX, I think it would take away too much of the car, unless you had a full Alcantara seats, door panel lining, armrest cover, etc :biggrin:
