Sorry Nonamex, past few weeks have been a sudden rush with work travel. As of today I still don't have the studs installed but glad to hear you were able to get them installed on your end. Let us know which rings you end up with; I've noticed small vibrations as well.

I ordered Rays Volk Racing TE37XT M-Spec 18x8 6x139.7 20mm Bronze QTY 5 & Rays 6H L33 19Hex Nut & Lock Set - 14x1.5 Black. Delivery is set for around February of 2026. After speaking with a Rays rep they told me that there was no issues with the above setup for lug to stud contact and that stock studs were long enough. Anyone else if you have more info for me I'd appreciate it.
With OEM studs you will get at most 5 full turns, which is not ideal. You would want to get at least 8 - 9 full turns for safety reasons. More so if you intend to take the vehicle offroad.
I would guess that the majority of people did not install longer studs and just went with plug and play. I opted for extended studs and will try out the smaller hub rings with the center caps.
Another option is to CNC the lug hole to 14 mm so you can use ET lug nuts. That was an option I would have taken if I hadn't gotten the extended studs. Just make sure you go to a reputable machine shop with a CNC machine and not some guy with a drill. The CNC route is less expensive and less time consuming.
By the way, most if not all Rays dealers will say the same thing since they either don't know any better or don't care.
I am with @nonamex on this one, but it's up to everyone to research and decide what is best for them based on how much risk they can tolerate. My wheels don't arrive for another couple of months but I have my longer studs, required tools, centering rings, and center caps ready to go. I am also going to paint my calipers for fun.
Pictures or it didn't happen
Nice! Mine came today but haven't had time to check them out yet.

Thanks for the info but…...We need pics!
I just finished installing the Rays center caps with the 106 mm to 95.1 mm hub rings. It worked!
Removed the 112 mm to 95.1 mm rings. Here are pictures of the OEM studs compared to the extended ones as well as the finished product. Since I didn’t perform the install, there are no pictures of the extended studs mounted on the wheel.

Brah….that’s a sick ride. The Volks bronze and Nori green compliment each other. Making me second guess my color options. The hub rings you got are aluminum or polymer? Last night I went over the whole thread again and bookmarked all the links to the items mentioned. I’ll consolidate them in a post later to make it easier to reference.

Ran into someone I know who runs a parts shop. He had TE37s on his GX460 and we got to talking. Turns out he’s a Volks dealer and said that Volks is currently working on a version of the ZE40X with bigger bores that will accept M14-1.5 lugs at full engagement. Hoping some other dealers can check in with Volks Japan and confirm.
If they do, I will get their wheels. I hope they do and do it soon.
Thanks to everyone else for the info. Great discussion.
One of the reasons I haven’t pulled the trigger on wheels yet. I don’t want to run extended studs. Figure Volk/Rays will continue to make wheel sizes specifically to fit the LC/GX
IMO I feel like running ET lug nuts is not a great solution for aftermarket wheels. The ET portion of these lug nuts are very thin and some have had issues with that part breaking off.
If you look at the OEM lug nuts the ET portion is much thicker, if the engineers at Toyota leave that much material on the lug nuts to me it's a signal that you need more material vs less on the aftermarket ET lug nuts.
I think in this case ET lugs will not be needed since the M14 lug hole will allow Rays lugs to have more thread engagement due to better fitment.
I did notice the Rays lugs are very robust, more so than the Method ET lugs. Heavier and pretty thick compared to the Method lugs.

That would be good but I doubt enlarging the diameter of the lug holes to M14 will lead to more thread engagement (unless they're making the part of the wheel that attaches to the hub noticeably thinner) everything else being equal a M14 vs M12 lug hole will show a negligible difference on thread engagement
edit for rough math - I think it'd be about 1.5MM more engagement or one turn everything else being equal

Good points. Hopefully Rays does take that into account with the new design and does more than just enlarge the bores since the root issue is adequate thread engagement. Even if they only did enlarge the bores, wouldn’t “mated” lug nuts that had the correct length and thickness through the part resolve that concern? That said, my preference would be a solution that does not require any proprietary lugs.
Whatever they do, I think I’d feel better with running M14 studs rather than 2mm thinner studs.
