Are these OEM Zanardi wheels?

[skafia]

I was led to believe I was purchasing 2 brand new rear Zanardi wheels but now I'm starting to question that after a closer inspection. Here are my findings:

- Color is identical to OEM wheel (including perfect match to center cap)
- All markings on the front of the wheel are identical to OEM wheel EXCEPT: OEM Wheel has "RG256", other wheel has "RG256A"
- All major stamps on the rear of the wheel are the same. 785C and SL0. The other numbers vary (confirmed with another Zanardi owner).
- Center cap opening has the same diameter, but the other wheel has extra metal on the backing, preventing the OEM centercap from being pushed 100% flush.

I know that the Mazda Spirit R has the same style wheels, but I do not have any closeup pictures of the front and back to confirm if these are Mazda RX-7 wheels. Also, I'm thinking the SL0 is a specific NSX part number, but I could be wrong. Anyway, I do not doubt that these are BBS wheels, and they are definitely not the RGR wheels, I'm just shocked at the very subtle differences in the centercap hole. Any insight would be helpful. Thanks!

They came with these BBS centercaps that fit perfectly.

Here is the questionable wheel with the OEM centercap. It sits very loose and not flush against the wheel. I believe if I shave the plastic tabs on the caps down a few mm it would sit nicely.

Bump, because this is an interesting thread, nobody's replied yet, and it's opened up hope/curiosity that there may be a BBS "same as" Zanardi wheel option out there somewhere.

Agreed, that would be so good to know!

SLO is NSX specific part number, base on that I would same it is Zanardi wheels.

Weren't the OEM Type-S wheels similar? It could be those.

The Type-S would have come with Honda center caps so that could be the difference.

Very similar to the NA2 Type S-Zero wheels. The wording "SLO" is of Honda derivation and used on literally dozens of parts throughout the entire Honda line.

interesting......what kind of center cap did Mark figure would fit in the smaller aperture?

I thought SL0 (zero) was purely NSX? This is the pass code to charging special NSX Tax

it is,here is an old post from parts guru Tim Poliniak on another site-

Decoding Acura part numbers
Here are all the vehicle codes I can remember offhand:
SL0 - NSX
This tells what kind of car it fits, or the first car it fit when originally created, in the case of parts that fit multiple cars.

yes,unfortunately the NSX tax exists for many parts...
