Who makes these wheels? Any good?
I bought a used 2007 Z06 that came with what I assumed were stock Comp. Gray wheels. Tires need to be replaced and I discovered that the wheels do not say "Speedline" or "Italy" as I have come to know that genuine OEM Z06 wheels should.
I photographed the mating surface of the wheel and would like to have some opinions about the safety and serviceability of these wheels. I do not track the car, I just enjoy it on the street.
Thanks for any wisdom you may wish to impart.

Wheels for '06 MY and the first part of the '07 MY were made by Amcast (not Speedline). Do your wheels have, on the backside spoke portion, have "GM" on them, would look like it was punched in there with little round dots (not cast)?
I don't have comp grey wheels so I don't know the P/N, but I do have a set of Amcast/GM wheels, and what you show, in terms of the way the P/N is cast into it and the three letter code/date wheel/etc certainly looks like they were Amcast/GM.

Did a little bit of homework. These are indeed Amcast wheels. I have the same "9594356" in my silver painted wheels. I learned that this sn't the part number but a reference number. The code under "USA" is a way of tracking where they were made (factory location of the wheel).

Here's a picture of a set of genuine GM wheels I run on my Z06:
It's hard to see what the info molded into the hub area says, but I took the picture mainly to show the "GM" stamped into a spoke at the top.
Also, you can see a "GM" molded into the plastic on the backside of the centercap (both on mine and yours).
The centercaps are very often a dead giveaway to replicas - replicas usually don't come with genuine GM centercaps, and the replica centercaps have generic crossed flags instead of the Corvette logo. Of course genuine caps will usually fit onto the replicas and may be added to non GM wheels.
Anyway.....it looks to me like your wheels are genuine GM wheels.
