I recently sold mine for just under $3000. I sold the wheels with the tires and tire pressure sensors, figuring that to break the seal to remove the pressure sensors was just setting up an opportunity for the tire guy to scratch or otherwise screw up a wheel. If you plan to put sensors in your new wheels, you'll need to buy the 4 tire sensors (Mopar P/N 52088990AC, list about $75 each) AND 4 tire pressure sensor nuts (Mopar P/N 52088961AA, list about $5 each). You will also need to have a Viper tech reprogram your car to recognize the new sensors.
I put the Sidewinder wheels on with Pilot Sports (non run-flat). Total weight savings (all four wheels & tires) was 40 lbs as compared with stock.
