Default Fitting Advan RG-D2 with NB Sport brakes?

While having seemingly lots of tread, the tires on my TiG MSM are beyond *** (can't even recall the brand - we'll say 'not well known' - from PO and likely pretty old), and while it's kinda fun spinning everywhere, it's not what I'm looking for.
Searched until my eyes about bleed and then some at this point for a light, decent wheel with a machined lip, as I can't quite get into the all-black on a TiG (although they're gorgeous on red cars). Was ready to buy the 6UL w/machined lip from FM, but no longer available,e and they and 949 said it's a one-off/no more to come. Have gone through a small bunch of wheels I'd found, either being discontinued or in some cases, unknown manufacturer I don't want to roll the dice with, while even 15x8 Beryllium 6ULs(which don't thrill me on a TiG, but would rock w/machined lip) are OOS seemingly until towards the end of the year.

Came up with the Advan Racing RG-D2, which I can get in 15x8 (will be mounting Conti ECI 205s..), apparently weigh around 12.5#, although Yokohama (parent of Advan) and most vendors have no clue... in either a 35 or 28 offset.
Trying to get Advan/Yokohama to answer 'will these clear NB factory sport brakes?' and they want be to magically come up diagrams for them, as apparently sport brakes weren't a thing in Japan?

So - can anyone confirm if either the 28 or 35 offsets in 15x8 will clear sport brakes, or does anyone have a magical source of diagrams for the sport brakes I can send their way?
Kind of big $ on rims to have them not fit or need spacers, especially when unsure can return 'em if they don't clear.

Checked out the mellens service manuals, no go there RE: dimensioned drawings.

Try reaching out to Rev9Autosport. It specializes in Miata JDM parts and he might know. His volk and fender flare pics, for example, are often accompanied by specs against offsets and such.

Yeah, so after contacting numerous vendors (Rev9 included who had some good info, but with shipping costs coast to coast somewhat killed it for me), one vendor with a solid price (still like $1500) but arguing with me stating they only came in 35 offset AND weighed 19# in 15x8, I tried to reach out to Advan on FB, and finally tracked down their US distributor.
Facebook was a joke:
1. How much do the RG-D2s weigh in 15x8 fitment?
2. Will the 28 offset clear Miata NB factory sport calipers?
Response: "I don't know, need to see the wheels in hand"
Ok, are you or are you not Advan Racing? WTF?

US distributor send me a bunch of measurements to get, but all communications was slow as molasses. Finally took a ton of measurements, pics, sent it all off, and meanwhile the US stock dropped to zero, so 4-8 week wait. Maybe.
STILL waiting on an answer a month+ later, so basically - I'm sorry you guys can't provide simple info and don't seem to actually want to sell your wheels or provide anything resembling customer service.

I might consider rolling the dice in the future if they ever show up in stock in the US, both otherwise, F them altogether as a company - not a good experience at all trying to get info from them.

Which is too bad, as I like the polished lip look on a TiG.
6ULs OoS until whenever, so went to Dekagram 15x8x25 and Conti ECS. Flow formed, light-is at ~12.5#, and finally ****-canned the 'Carbon Series' rocks and Racing Harts on the car when I bought it.

I have a MSM with 15x8 +35 and 205-50-15 ECS. They're awesome - I think the wheels were around 12.8ish when I weighed them? My instagram handle is @fly.mx5 for photos, should be enough on there to help you decide.
Brake clearance is plenty, I'm looking into BBK's and don't have much concern.

edit: didn't realize you already bought different wheels. wish I would have seen this post last month :(

Yeah, all good.
Claimed/semi-confirmed weight is like 12./5#, so 12.8# still close enough vs the one vendor arguing with me about them being 19#.
Was also trying to sort through going to there 28 offsets vs the 35s, thinking the 28 would give more clearance inc case I do a BBK later down the line, but overall dealing with, or trying to, both the mfgr + US distributor when I could have bought them and had in hand in a week to OOS for 'who knows?'/coming from JP...I'm good saying screw Advan for at least a year at this point.
Will check out the pics though, as I did like the wheels in general, just the company and distributor is seemingly crap.
