This mod faithfully emulates the famous gear whine of this amazing car. It ACTUALLY pretty much gets it right. Automatic high rating from me, then!
Only things holding me back: the odd folder structure (which I changed before installing), the off-throttle gear whine ramp-down could be a little louder and richer, and the underlying engine note could be a little more vicious and have more growl to it. But pretty good overall!
