I just got my charger last week, and have put over 1000 miles on it so far, lol. The other night, I totally floored the gas and spun the tires and upon takeoff, I noticed a loud vibrating noise in the rear of the car. Any ideas? I tried it with the traction control on and with it off, and it still does it. Also, with the traction control off, has anybody tried just laceing the gas, and will the tires spin, or will it just hook up and go?
