Hi Stainless
I looked at your seat belt setup and here are my thoughts for what they are worth. The general rule is the shoulder harnesses should be a minimum of 4" below the shoulders and should be as close to the back as practical. This keeps you from moving upward. And protects from neck vertebrae compression fractures. During Rocky's 2011 crash he came down right on top of the bike from about 6 - 7 feet above the ground at about 70 mph. I was right behind him and immediately worried about a compression fracture as his helmet only has about 1 inch of clearance on top. Within about 20 minutes after the crash he was totally black and blue from his shoulders to about 8 inches down his back but he had no neck pain. They obviously did their job. When I look at your setup it looks to me to not provide much protection from the helmet impacting the roll cage or from you moving back in the event the vehicle impacts on its tail. We use a 9 point harness but Rocky is in a much more upright position so I don't think it would be of much benefit in this case.

Mike, I appreciate your input... When we initially started the original builder had the belts designed to go over that upper bar, would not hold the shoulders down at all... at the first fitting the shoulders were at the center of that oval hole for the dzus.  So I thought this might work by installing a bar lower, but during this fitting I saw the same thing you saw, it looked like the the belt would hold the shoulder down, but the space behind had me concerned about moving back as well.  The belts actually attach very close to the spot you showed.  During the fitting I routed the belt without going around the bar and it looked better.  I told Ross I had a backup plan if the routing didn't work out...
One good reason for posting pics of all of this is so Members here can throw in comments... yours from experience mean a lot.  Luckily all of that is just tacked in... OK it's if tacked pretty well, I didn't want any to pop loose while we were checking the fit. 
A little rework on this just hit the schedule as next.  :cheers:

OK Kids, its been a while.  I did get the seatbelt moved forward to a better angle.  I will get some pictures.  Been trying to get back on this one, but motor building for the lakester has taken its toll on this project.  Of course those motors will transfer to this project as time goes on. 
I can also blame the new Harley project, but that's another story.
:cheers:

I mentioned somewhere I was back to work on the Liner... I'm installing floor/seat support, much like the lakester has.  It will help stiffen the roll cage and provide a solid seat surface when the seat sheetmetal is installed. 
Hey the photo attached... it's getting better Mike, keep up the good work
