Seeing as I no longer have any good RF's til I wear a new one in and therefore can't test much, I weighed all of my Limited-Legal Metal Wheels (and MW-analogs) on my scale (finally found that calibration weight, so this is all fully calibrated and to .01g), and figured I may as well stick the spreadsheet on google docs and post the link in the relevant threads.
Source and/or mold is listed where known (for the metal system ones that are from either the starters or boosters I just listed the paint, can't be bothered working out specifics), I don't have any fakes, etc etc. If a part is noticeably worn, I mentioned that in the notes too.
I may update this when I get around to weighing other parts, though odds are I won't do much in the way of rubber tips (due to wear) or faces (due to the fact they're all within like +/- .02g of each other) even if I do.
I know most or all of this stuff is on beywiki, I mainly did it to keep track of my parts and their weights, there are also some molds we haven't got any real mentions of at least on beywiki, such as the one storm mold and my various rays, which I can take pictures of if needed. Obviously any and all of this data can be used for WBO-related work etc etc on the off chance it is at all useful.

Some interesting (to me at least) things I noticed:
The 0 Cylinder Rock mold I have is no lighter than my 6 cylinder ones (0 Cyl TT: 32.55, 6 Cyl TT: 32.59, 32.42, 6 Cyl Hasbro: 32.29), and I've worked out why - the overhang is slightly larger, making the MW taller. This conflicts with what is on beywiki, and I'll probably take photos to show it when I've charged my camera's battery up, and correct the article in the next couple of days.
My RB7 Vulcans are significantly heavier (by just over 1g) than my BBP-01 one, I vaguely recall knowing this beforehand so it might not be new info (though it's not mentioned on the beywiki article), not really sure where the extra weight is coming from but that's mostly because vulcan's shape makes comparison via naked eye difficult
Sol, or at least the mold I have of it, is actually the second heaviest Pre-Maximum Series Hybrid System Metal Wheel, behind only Gravity. Shame about the shape, though I might do some defense testing just in case, seeing as mine already has a scratch or two. Tornado is also really heavy, though it narrowly misses out on the 33g mark beyond which Vulcan, Sol, Gravity and Screw (and my heaviest Flame) sit.
EDIT: I'll have to do some formal defense testing for Sol once I wear in an RF. It's not as good as Earth, but it's nonetheless quite solid, a lot like Nightmare but better against things hitting from different heights (Nightmare is not so great at being hit from below). Could be worth looking into for anti-attack, seeing as it's heavier than any of the other defense wheels I have that can KO MF-H Gravity Perseus (STA) B: D (weak launched).
EDIT 2: Eh, seems okay but still doesn't seem like it has enough defense to be a great anti attack wheel, while Libra, the most suitable wheel for it, can't do anything to spin stealers. Bah.
Screw is heavier than any pre-maximum series hybrid system metal wheel and with the heaviest CW I own, a 3.5g Kerbecs, comes out behind only Libra of all my Limited-legal Metal Wheels and Chrome Wheels (with Samurai). Of course, Kerbecs is a horrible CW for screw, and Screw Pisces with my heaviest Pisces is a little lighter than Virgo though still heavier than any Gravity Perseus (Stamina) I can make with my parts.
My Hasbro Burn is about half a gram lighter than any of my TT burns, rather than being heavier - curious as to whether the idea that hasbro's was heavier was based on actual weights or people assuming the engraving had been filled in and thus the wheel was heavier.
My Leone is lighter than my Virgo, and significantly lighter than the 38g listed on BeyWiki, much more than any feasible margin of error, too.
Also, I played around with Poison today, and honestly unless Torch or Hyper are somehow even less useful, Poison is the worst wheel in MFB by a solid margin, I can't even make it KO Earth Bull AD145WD reliably, though admittedly my non-mint RF's are all well past prime now. The only wheels with worse Attack all have much better Stamina and Defense, and the only things with worse Stamina or Defense have much better Attack.
Edit To Avoid Triple Post: Updated my Spreadsheet with Clear Wheel weights (as well as Samurai).
Some things I noticed and felt mentioning:
All of the Perseus CW's are extremely light, the attack versions only being beaten to being the lightest CW's I own by a very light gemios.
Kerbecs is, as is generally well known, the heaviest CW by a significant .2g margin. Unicorno II comes in next for me, just ahead of Bull, though if Bull has sizeable stickers that I didn't apply maybe that could tip the scales in its direction (literally). IIRC Ingulit found his multiple Hasbro Kerbecs to be no heavier than Bull, so they may have altered it, as the verdict from my weights is pretty clear.
MLD (Absorb) is heavier than Samurai, which is supposedly one of the heavier chrome wheels.
There are fairly large weight differences (~.1g in some cases) between some of my identical-origin Clear Wheels, for some reason. Considering they were weighed consecutively, this isn't due to my scale freaking out or anything either.
Some of the smaller CW's such as Orion and Horuseus are actually around the 3g mark, which is decently heavy.
Leone II is lighter than its predecessor.
My opaque Pisces is significantly (.3g) heavier than my transparent one, despite both being Hasbro. Some of the details look a bit fatter, which I guess may be the source.
EDIT 3: Updated again with Tracks and Tips. I could've sworn my two GB145's were around the same weight but they're actually .2g different. Also wear seems to have almost no effect on the weight of rubber tips (though I haven't measured any before and after significant wear), in some cases my worn tips are heavier than my mint ones :\
Oh also, X: D is hella heavy, R145MB (my heaviest track and tip combo) comes to 6.23g, whereas X: D weighs in over a gram more at 7.26g. Shame about the self-KO issues and all that.
EDIT 4: Updated with my new ZG parts weights. Chrome Wheels are in with the MWs and Crystal Wheels in with the Clear Wheels but I might split them off if I feel that works better, not sure yet. Also A230GCF is slightly heavier than X: D, though A230 is awful so it doesn't really matter.
Just realised I forgot to weigh divine chimera's parts so I'll do that in a little.
