The unilug aspect is another reason I'm a bit turned off on the Cragars as well. I've had them on other cars and was always worried about them loosening up thus constantly checking torque.

I agree on the polished, dark colored cars look best with shiny wheels.
I'm hesitant though as this is going to remain somewhat ratty looking, I wonder if it would look a bit out of place with nice shiny wheels vs. the as-cast finish.
