Dude, you're insane. You ask everyone's opinion about the roll bar, then accuse everyone of e-thuggin'.. the simple fact that you don't know how the harness attaches, doesn't lend any credibility to you either! There isn't a single series in North America that would allow rear bars like that.. SCCA, NASA, ALMS, Grand AM, you name it. There are angle requirements for the rear bars and some specifically require the rear down bars to attach to the suspension pickup points or shock towers.
The point of a roll cage is to provide some cage or structure around the driver when the body crumples in a crash. If the roll bar attaches to the upper *body*, how does that work? Your bar looks like a nice harness bar that could possibly provide some structure in a roll-over. AI'm betting as soon as that car lands on its side, that down bar is going to bend inwards, allowing the mainhoop to collapse.
If you want clarification, check out the NASA's requirements for downbars. SCCA and everything else will be the same:

Page 61. Instructions on how to attach the harnesses are on page 59. Here's an example of a legal roll bar.. or should I say, you could drive on track in HPDE events all you want with that, but it'll never pass a race tech.
