Threaded fasteners (the lugs) are meant solely to provide clamping force, that is the wheel to the hub. Work a threaded fastener in a bending load and sooner or later, after enough cycles it will fail, just like bending a strip of metal back and forth in your hands. The mentioned mating of the flange on the hub to the wheel does far more than position the wheel during torqueing, it transfers the WEIGHT OF THE CAR TO THE WHEEL AND HENCE TO THE PAVEMENT. Threaded fasteners are never intended to bear this weight. Why is no Honda (NO OEM for that matter) wheel ever supplied with those silly rings, because "lug centic" is a crime against threaded fastener NATURE, and it is not nice to fool with threaded fastener NATURE. It is so aftermarket wheel manufacturers can make one wheel that will fit many cars. That is why I blanch continually on many of these forums when someone asks if something will "fit". That being said, it is all theory (albeit correct--my single seat formula car racing days and threaded fastener sales career give me "cred" as you kids call it) and I know of no one whose wheel has fallen off because they have a plastic ring between wheel and hub. However if I ever bring my 5th (last) Gen Prelude to a Dragon event, with its "lug centric" Kosei wheels (I bought it used) and I fly off into the trees after a wheel departs, at least as I go through the trees I'll know why! SORRY FOR THE RANT, don't even get me started about wheel offsets, wheel bearing loads, scrub radius, WILL IT FIT???
There are very few wheel truly made for the S2000. Such a wheel would be:
1) hubcentric (front and rear)
2) have steel inserts so the OEM ball type Honda lugnuts can be used
3) OEM size (17x7, 17x8.5)
4) OEM offsets (55mm, 65mm)
some additional nice features could be:
1) forged monoblock
2) Made by Enkie
Such a wheel does exist. TR Motorsports F3

I regretted my high horse theory based post the instant I hit the add reply button. Thanks to TubeDriver for a nice response. I wouldn't require the ball seat inserts (but it would be a plus for sure), and if these centering rings were made of steel or aluminum, so that the weight of the car was hanging on the hubs not the lugs, even I could relax. I've never seen these offered for the few sets of A/M wheels I've owned, but I'm sure they could made up by any machinist. Remember, I have not even taken my own theory based advice on my own Prelude, but if you look in any race car preparation books, they would not even discuss the merits of hanging the car on the lug studs. I guess I get so nuts when I walk the softball field at the Dragon and see the unbelievable amount of money many of you have put in these fine cars, only to overlook primary engineering principles because it will really look cool, or "fit". Maybe TubeDriver's wheel recomendation will excite this cheap old Polack to change to 17's on his 01 so I can buy real 245s again.
