I was sold on the srt vehicles when I drove the srt-10 last summer. We had an animated discussion yesterday about whose car was faster and knew that we would be neck and neck. I have the 3:93 rear end. Does anyone know what rear end the automatic srt-10 came out with? That might be the real difference. I did blow off a Ford Lightning the other day. Its owner looked surprised that he did not have the quick acceleration that the challenger has. My g/f still thinks I got it for the hands free phone lol !
