Hubcentric Ring size for ACS Type III

[EganM]

I've searched here as well as on google and came up empty.

I just acquired some 18" ACS Type III wheels for my M Coupe. The previous owner did not have hubcentric rings and/or did not ship them. I have no problem buying some new ones, but I have no idea what the size is.

My calipers do not fit in the wheels and I don't trust a ruler for such a critical dimension. I tried fitting the rings off my SSR's (which are stamped as 79.5mm) and they're too small. Does anyone know the exact size hubcentric ring I need?

I also have ACS Type III's. The wheel bore is 82mm and the center bore of the ring is 72.5mm. Below is the ring and bolt part #'s. Price is per wheel. Also the contact info for CEC. He is the ACS importer. GH
Front, 72.5mm Center rings and 12x1.5x27mm bolts: 3613 99250: $29.00

Much thanks!

I contacted Walter earlier this morning, but he needed the part number from the wheel to be certain (and I won't be home for a while yet).

I'll shoot this back to him and get them ordered.

While you have Walter you should ask him about your application. He will tell you what offset and tire size to use and if spacers are needed for your car. I would also note the offset of your wheels with the part #. People bitch about what ACS charges but at least they know what they are talking about. GH

Was that $29 for one ring or four?

[EganM]

All four.
