I actually completely disagree. The bar was very well engineered for this not to happen. All of the forces being applied to the bolts are in sheer, and the steel is 350mpa CDW roll cage tubing. If the lower bolts (M8, 130mm long, grade 12) and the spacers are used, the bar physically cannot pivot downward. Also, bolts actually replace OEM mounting points of the support bar to the frame(strongest points of the car), zero drilling/modifying needed.

Here are a few photos in the raw of the actual connection points. You'll see that they do not go into the "support bar" which is very thin which is not recommended to support harnesses, rather they go into the actual supporting joints to hold in the support bar which are much thicker. Also, they bar goes back far enough to fully be prevented from rotating downward in the event of an accident, so all of this talk about it rotating around in the event of an accident, is irrelevant.

Good point about the anchors being off centered, I didn't even notice that.

The mounting points arent perfect but I think they are better than that of the robi bar. I say that because those points are designed to be load bearing points and should be safe in a crash. If the bar is safe is a whole other question.

Take a peak at the difference between the bar you posted and this one in the same raw stage. The bar is solid from end to end, and comes backward with sheer connection points focused on quality and safey.

That does look much better can't deny that.

I have no idea what you're talking about but that bar in the pic is a waste as there nothing holding the center from collapsing and again the robispec bar is not designed to be used as a harness bar because nissan did not engineer the mounting points to take a load like that. Anyone who runs anything besides a real harness bar mounted to a roll cage is a complete idiot and good luck living through a crash. I'm done talking about this retarded topic as it never dies.
