I understand what you're trying to do.
I ended up buying a 2nd set of 5-spokes from another ZL1 owner
and getting them black powdercoated.
Then I had my dealer swap the original bright wheels with the
black powder coated wheels.
I will sell you my bright 5-spokes and you can do the same thing I did.
It may not be the cheapest/easiest solution for you.
