I have had my srt6 at top speed which in my car was governed to about 158 mph and had a friend in there with me and it was so stable he didn't believe we were going that fast until he checked the speedo for himself, so stable that it surprised me. But I was on a straight stretch of empty fairly new road as well. But as far as feeling light not at all but the srt6 also has that big wing in the back and I'm sure it did its job.
