What is the centerbore diameter on my original IROC-Z wheels? (IROC-Z 350tpi 1987)
Is it 2,862 in?

Technically, the hub is 2.780. The center hole of the Iroc rims is made to be hub centric and fit somewhat snugly on the center portion of the hub so that the wheelstuds to not take all the lateral pressure of the wheel when mounted. Hence the opening is just a td larger so that it is not a press fit and can be put on and off the hub easily. It should be at most about 2.8 from casting imperfections and wear.
Rims don't have to be hub centric, but are easier to mount AND much sfae to drive aggresively on if they are.

I want this wheel to fit my camaro...
Everything seems to be working, but it stands "No hub centric" Do you thing that it may work with centric rings?
