OZ hub centric ring on 1998 Audi A4 1.8T quattro

[vtraudt]

We have these OZ wheels (17") on our A4. Lost one of those aluminum hub centric ring (and other may not be in good shape anymore either).
the approximate hub bore of the wheel is 74mm.

Don't know the 'official' name of the wheel (does someone know?).

What is the CORRECT size of the bore?
Wheel hub is 57.1mm

Where can we buy them?
Part number? Price?

nearly all the OZ centering rings will have the size (preceeded by EFS) so you may have the part number needed if you have an original ring remaining... I'll have them at $5 each.

The wheel you have is the Hydra model for reference.........

This is what we found on the ring:

L-Z 5706

Also "patent"
the 5706 from above actually seems the diameter sign plus the number 5706

I've got an OZ part # L-57.06 specific to Audi with 75mm OD and 57ID in stock. Everything else is a 79mm OD, but no 57mm ID so no go there. Our part number is EFS75/57;
