I think that black satin would be the better choice. I photo shopped nightrunner rims on a mineral grey and it became to much of the same thing.
with black rims there is contrast. Feel free to take a look in my garage; there is one picture of my SRT in winter setup. The winter rims are oem SRT rims in satin black. (since that picture the head lights are nightrunner ones)
For a bolt statement you could try red (same as the 2006 srt badge) and paint the calipers black...
Orange rims would contrast the mineral grey as well...
I'm in the process of changing the color of my summer wheels (also OEM SRT). I thing i will go for polished and then give them a clear coat with a certain (that i still have to figure out) % black in the clear coat. So to say to get a deep polish shine through the blackish clear coat, or something close to that (it's difficult to explain...)
