so after a complete run around with custom rims i ordered, delay after delay, then excuses etc eyc, i'm again looking for an original set of wheels. Although not original, i have yet to see a Challenger sporting these:

another site member did a quick photoshop, and I think these will look stellar. 20x10 in the rear with a nice lip, and 20x8.5 in the front. Brushed centre with polished lip.
