has anyone seen this type of wheel for sale? are there modern replicas? trying to find some for my 75.

 

Pretty sure they're not GM and likely long out of production.
You might try a google search for reproduction wheels and start surfing whatever sites pop up,might get lucky in the used market on ebay etc.

 

Not any GM rim I can remember. GM iroc wheels are 5 spoke. Some look like 10 spokes but that is how they are painted. That looks like an 8 spoke. That looks like a real race car. They could easily be made to order magnesium rims not mass produced. Heck they may not even be DOT approved. They tend to have custom widths and offsets and even diameters. No telling if they would fit a stock Camaro even if you could find them. With those flairs the backs could be 12 inchs wide or more and they would likely hit your leaf springs.

 

Well put,that's a real IROC race car for sure and the wheels centaily would not fit a stock Camaro,finding that "style" might be possible but doubtful,maybe something similar.

15” Minilite magnesium wheels

Based on what I found those are magnesium and the company is still around and they do make an aluminum versions. They are not mass produced but they are more common in the UK. They are not budget wheels. Seems like Porsha and MG sports both used their wheels as options. You can find the original race car ones but IMO Magnesium Wheels should not be run on a street car. They can catch fire, you would need a special extinguisher. Magnesium will burn and it burns at 2500 degs most steels melt at 2200 degs. That means if you have a fire on a bridge the rims can burn right through it. Your insurance will not cover that

There are Aluminum knock offs around.

I liked your picture and I was going to add it to my Camaro screen saver. I found a good pic from an auction and it listed the wheels name.
