Making the hard top glass larger all around greatly reduced blind spots. I sat in a friend's 2010 model and compared to my 2012 it was noticeable.I never quite understood the change they made to the window real estate on the JK's 2011+ hard tops that did absolutely nothing to improve visibility. It was the tire carrier and the rear headrests that were the problem, not the windows.
I can't quite tell, but other than making that rear window significantly bigger, I wonder if they lowered the tire carrier at all. And I do not see a wiper up top, either.
