These are the front spindles for a 1998-2001 Hyundai Tiburon. This hub assembly only fits the 1998-2001 Tiburon with 4 lug wheels.

What is the bolt circle diameter? That could narrow it down for me.

Reason:
The hub size is 4x4.5 (4x114.3).

Okay, that helps. If you can, the thread pitch diameter on the lugs as well as the hub ring outer diameter (in metric, if possible) would help me further. There weren't too many cars made with that odd bolt circle.

Reason:
The diameter lug-to-lug (center hole to hole) is 115mm. The outer diameter of the hub is 141mm. The thread pitch on the bolts looks about 1.30mm.

Actually, it's the hub-centric ring I need the diameter of....the raised circular piece in the center, not the entire hub itself, and as for thread pitch, the closest it could be to 1.3 is 1.25, so that helps a little more.

Reason:
Sorry for the delay, but the hub center appears to be closer to 5.75" across.
