Default Help. What wheel is this?

I bought an extra set of track wheels. They are all 18 x10.5. Three of them are Speedlines from an 03 Z06.
The last one looks and feels the same, but does not say Speedline.

Stamped on the inside of the spokes are the following:

GM

F-12-13-00

USA RG G158

9593805

011102

The weight appears to be the same but the spokes appear to be SLIGHTLY thinner.

Any experts out there? Is it an Alcoa? Any knowledgeable opinions would be appreciated.

Cheers,
CV

Here's a photo of an Alcoa wheel. Alcoa's are not spunned aluminum like the Speedlines and weigh 1/2 to a pound more per wheel.

Default Bingo!

That's the one. Thanks Darrell. I am going to send two of the 4 wheels to Weldcraft to be Widened to 12". I think I'll use the Alcoa and one of the Speedlines as rears on my car and run the matching Speedlines on the front.

You're welcome! I wasn't aware that the stock wheel could be extended. How much per wheel does it cost and where are they located?

I've been looking at replacing my bent Classic CCW's.
