I know this is me just being thick about subtle yet important changes that could have possibly come from the demo, but: The only change I see and feel regarding the change in physics is (extendedly) softer suspension. For example, the first race(s) with the Nissan Leaf have the outside wheels nearly bottoming out, with the inside wheels almost lifting. This does seem realistic and reasonable, and also explains the ability to get a bit of a slide on when you really throw it around Yet, I wonder if this could be replicated with GT5'S suspension settings...? Another observation I made is that the cars in the demo have progressively harder suspension (visually, with regard to the amount of body roll) in relation to their performance, which does seem reasonable as well. Someone please enlighten me about these "changes"
