I have only one problem with your mod and that is that red colour isn't the same with your mod like it used to be, so Ferrari doesn't look the same way like in original and the way IT SHOULD look. And not just Ferrari, of course, every red texture in game have some... darker look. It would be perfect if your mod could afect only scenery and not the cars but guess that's impossible.
Other then this "red colour issue"... I see no other problems. :)
