Here's a guy that did it with a Prius. Don't believe the numbers but he has a faily detailed look at it.

This is what one guy on the prius forum said.


I believe these numbers.

I don't think that would hold. I use disk magnets for the quasi-baby-moons on my steel wheels (see garage) and lose one every month or two.

Re: Hubcaps?
 

Could you show some close-ups? I'm pretty handy mechanically and sure I can do this. Cheaper than the damn moons and won't fall off!

I'd like to know what you did for centering, length of screws, etc. I'm sure I can find the pizza pans :)

And since I started this thread, I figured it was finally about time I should pick up some of those Cripe 14" disks. Like you, I only needed one set (in this case for my CRX), but since they are so cheap I ordered a 2nd set so I would have some spares (if I either lose a disk, or one is damaged).

Once they arrive, I expect I'll probably have to drill a small hole in them, so that I can have access to my valve stem (especially the visual marker I have on my stem, that lets me know when my air pressure is low). And I imagine they might stay on better, if I paint a little paint on rubber (which is easy to buy in a hardware store for a few bucks a small bottle) on the spring loaded teeth that hold them in place. But otherwise, I expect them to be pretty easy to put on. And I'll even get back some of the extra hubcap weight, as I intend to remove the existing OEM "center caps" from the wheel, before installing these new hubcaps. So the only "extra weight" will be the difference in weight between the new hubcaps, and the wheel center caps I'll be removing!

BTW: The forum post about the Prius owner (that someone else linked to in this thread) probably does put smooth hubcaps in perspective (as an aerodynamic mod). After all, around 1 MPG for a 50+ MPG car, is around a 2% gain from the hubcaps. i.e. enough to be "worth while", but small enough that it would be easy to miss the benefit unless you already have a high MPG car. And I wouldn't be surprised at all if that number is about right. However, either way, I suspect my car will look a little nicer with the hubcaps on, even if I don't get a (small but) noticeable FE boost.

Found a great article on do-it-yourself moons!

Very neat application of pizza pans! Think I might try this myself!

OdieTurbo -

Many I wish I had seen that years ago. Very clean design. Must look cool on the freeway too. I wish I didn't have alloys.

I'd drill & tap alloys to put smooth covers on - if I had alloys.

If only my VX rims had fit my Firefly. If only....

Alloys sure look nice, but I'd still cover them up.

MetroMPG -

I really don't like alloys to begin with. I like the ability to change "the look" of the wheels, and alloys just leave you stuck with someone else's design. I'll add it to the todo list. My alloys are pretty scuffed up, so it's not like they are worth much for resale.
