I'll try to answer a few of the questions asked:
The reason its not "full length" actually has nothing to do with the freedom panels, keeping those fully functional was just a bonus of our top goal which was low wind resistance/noise. As we moved the leading edge of the rack back from the windshield, wind noise was noticeably reduced. This rack can easily carry more than you should ever load a JK with so its really a moot point.
The rack sits about 2.5" off the roof and is 1.625" thick, so it adds less than 4.125" to the overall height when you factor in the curve of the roof is being taken away.
Keep in mind that the absolute goal with this rack was to make something that was, as we say "liveable", meaning its easy to live with and doesn't interfere with your life or your enjoyment of the vehicle. Our Tire Carrier had the same goal and its seems to be much appreciated. Lets face it, though the cool exo racks look great, (especially on a Rover which has a 65mph top speed and you can't hear the rack over all the other stuff anyway (and yes, I'll admit it, I love rovers too)). I wouldn't go so far as to say when I see one on a JK, I think "oh that person has no idea" rather I think "wow, that person wants that look so bad that they are willing to live with all the creaking, wind noise, reduction in mileage etc for something that probably gets used once a year if that." Racks are great for hauling bulky lightweight items, try to load them up with heavy stuff and they hurt performance horribly. That's something I'm not willing to live with and I think most of our customers or colleagues (like Scott Brady, Dave Yegge, Chris Wood) would certainly agree that Racks and RTT's have a place, but ideally not as a permanent fixture. We made this rack to behave as if it wasn't there because lets face it, they become permanent fixtures. That's why its lightweight extruded aluminum and that's why its sold without the top rail primarily. The top rail is really just for looks, but we offer it. The rack is far more useful as just a strong flat platform that is easy to put stuff up on.
