I seemed to have missed this thread, great discussion.
The past few years for me I've explored what is possible in my zed, it never ceases to amaze me just what our cars are capable of, I have a few mods but nothing too serious which allows some spirited driving. When on track the limit for me is getting closer but I guess my car could achieve more in different hands, my limit does change though as I get more experienced, there are corners on tracks that I have been to a few times that I will now take at a higher speed because I am more confident, the faster speed does not men that I am being reckless, I just know that the grip is there. Of course the limit for me (and most others too I suspect) changes dramatically from wet to dry conditions, I think I am fine with the level of my "limit" if it got any higher I would s@:t myself!
