There are a few companies that offer replicas of that wheel without the high dealer cost. Check a local wheel shop to see fi they carry the O.E. Replica brand wheels. As far as trading that is pretty unusual for shops to do, used wheels aren't always easy to sell at a tire store. Try listing your factory stuff on Craigslist, even include that you'd like to trade for SRT wheels, there may be someone who has a set that needs tires, but wants to switch to the less expensive 20's.
