pair hubcentric wheel spacers 30mm

[batchman]

New, test fit only, believe to be H&R, bought from TireRack a few years ago. What you see is what I've got. These were not the answer for our setup but maybe you have something you would like to try.

Figuring $60 shipped continental US, obo. PayPal, check, whatever.

Best of the new year to you all,

I can't read the caliper in the 4th snapshot which would be the "wheel bore diameter". The bore of the adapter looks to be GM 70.3 so that would indicate the OD for the wheel bore might be an issue for a GM application using a GM/OE wheel. What is that dimension? You might confirm the 70.3 on the back-side of the adapter also.

Doh - downsizing seems to have hurt legibility - sorry 'bout that.

They do have a "GM" cast in, I'm not at home but will re-measure later.

Thanks/later,

BTW, they appear to be BOTH hub and wheel centric which is an important point.

Hub centric to a GM hub (70.3) but wheel centric to what? That's the dimension I can't make out in the snapshot. The back-side isn't actually dimensioned but if you assume it's a consistent bore throughout the 70.3 holds up. Hub & wheel is important but the wheel-bore dimension is important to someone that's interested. It will certainly make them easier to sell for the OP if he knows for sure. They're quality pieces for sure and there's a slight taper on the hub/back-side similar to an OE wheel. That's not done on all spacers.

If you look at the pics closely you'll see that there is an inner chamfer on the adapter to center it onto the hub. Additionally there is an outer lip on the wheel side. This lip helps center the wheel onto the adapter. So the adapter is now centered onto the hub and the wheel centered onto the adapter maintaining concentricity of each component. The measurement for the wheel centric should be the same as a standard GM hub. It's made to mimic the hub for the wheel.

Just realized I did measure the hub side at about 70.6 or .7 (a little hard due to the clearance at the hub face vs the adjust knob on the caliper), and they do "nest". So that would seem to mean no 80mm centric here.

HTH for now,

Ever figure out if they are hub and wheel centric for corvette
wheels?

Appears I've ended last year with a twist. In my defense I'll point out it was maybe 5 years ago when we bought these, I bumped into and took 'em out last summer and took pics, then a couple months ago re-sized those to be post-ready, and just now I have gone back and re-confirmed the following:

They are Chevy bolt pattern both directions, 5x4.75".

They are centric on the GM hub, measuring 70.6 or so on the hub side.

The snout, or wheel side, is 81.7 or so. They do not fit in the clone A-mold I had handy. They do fit in my CCWs, which I do wish the spacers I wound up using would support (those are flat).

Thanks for the watchful eyes, folks - wouldn't want somebody winding up with the wrong thing.

Best of the new year to you all,

As it came up in discussion, I am happy to offer a refund less shipping if these do not work out for any buyer. So you can test something risking only the transport.

Thanks and regards,
