I have the Super Track Pack on my 2010 R/T with an automatic. I can testify (after what happened today); that it totally disables ESP. I drove down a new road that dead ends in a field. The road was dry. I nailed it and just about did a 180 before I knew what was going on. I hit the throttle again and ditto. I finally gave up and drove home nicely. If you have this feature, don't try it out on the streets, unless you want to but new wheels after you smash them on the curb.
