Hub centric rings?

I've got TR Motorsports (tire rack) rims, ff10s. They were originally bought for a Subaru, I got them very lightly used at a good price. I confirmed bolt pattern, fitment, etc...all clear (literally, will add this to any questions of this).

Ive got to buy hub-centric rings to adapt them to my 12 si. Quick search on the internet said car is 64.1 for hub, my Mitutoyo (very high quality) digital mics say 64mm even. Zeroed out fine, and they measure 79.5 on the rim bore, which is what tire rack said when I asked them about the rim bore size...leads me to believe that my quick search was wrong and I need 79.5 - 64.0 hub bore adapters.
Any ideas or respone regarding my 64 vs 64.1 dimensions?

Thanks in advance, and please don't question rim size past the adapters, I only have questions about hub centric ring adapter size.

The 0.1mm shouldnt make any difference. Honda spec is 64.1mm and most hub rings will probably be offered in that size. If anything it gives you a little clearance. My hub rings always got stuck to the hub and were a pain to remove.
Make sure to get plastic ones. The metal ones are a disater.

Tire rack physically cannot look up just centering rings. They auto fill this information when ordering. Luckily through Google and other people reporting solutions for their issues, I found a part number so tire rack could sell them. *AL641*, these are 79.5-64.1mm hub centric rings. Around $18.00 shipped.
May be .1mm too large I.D. for hub, but if so I'll have the original rings for a Subaru turned down to 64.0. Local machine shops are backed up till Wednesday.
These are not a item you want oversized, as they center the rim to the hub. If there's wiggle room, you may break lugs or have vibration issues.
Plastic is fine for a daily driver, but not for performance applications. Ford actually places small amounts of grease inside the rim for the hubs to keep them from rusting together on the super duty, expedition, and navigator (probably others as well)

I hear ya on all of the above but I just highly doubt you could even tell the difference of 0.1mm?
My experience is on a daily driver in Maryland where we get salted roads during the winter. No way I would put metal hub rings on my car.
Glad you found the right ones, post up pics in the wheel thread once they are mounted.

Not sure if I'll tell the difference of .1mm or not, thats .050mm wiggle in either direction. That may be the clearance spec, +/- 50 microns is common for Honda at least from a machining standpoint. Looking at my wife's Tacoma, it seems to have a 50 microns of space around the hub. If it doesn't seem right when I put it together I'll have plan B and cut them to size.
We get snow here too, and I've worked on other people's car that required a torch to remove the rim. I just don't want to hit a pothole and think I'm deforming plastic.
I'll post pics up when it's finished, dealer has Continentals extreme contacts ordered. Wanted re-71R but couldn't get them discounted.
