Since your car is brilliant Silver (plain) I wouldn't unbalance the car with Black wheels. What about car colored wheels? They'd look awesome with the rim edge polished aluminium.
The Black would be too dark for your color (in my opinion) although Black would look awesome on a Grey with Black striped car. Ummm, maybe Dark stripes, tinted markers - like Jason Tiff's last GTS? I admit that the clouds did add to the pic of his car, but he has one of the best GTS pics around (of his silver GTS)
-Eh, Jewels???
