I think if you look at "most" if not almost all the different seats out there you will find just one hole that should be wide enough for the straps to be away from each other. The separation of the two straps is what is important. It pulls the two straps to the side and leaves room for the family jewels. Also the two straps are sewn into the harness hardware so there is no way to get them through two holes without threading them through the seat before attaching the belt and the seat to the frame. Not only that it would be a bitch getting the seat in and out because the straps don't come that far through the hole to attach to the harness. You also would have to undo the webbing each time you took the seat out. I can almost guess you haven't attempted to do the webbing yet. Can you imagine how far your legs would have to be apart to do it that way?? I can't remember seeing two holes on any seats. Evidently there are some out there, or your tech guys would not have said you need them. Lots of luck on doing it that way, cause your going to need it when you try to do it that way.
Personally, I prefer the 5 point harness. 6 point is very messy, takes a long time to get together, and grabs in all sorts of places. :shocked:To update this thread, I spoke to Schroth and they said their 6 point is designed to work with most racing seats that have a single sub belt hole.
One thing I've found is that although there are general guidelines for anchor point angles and things like that from sanctioning bodies, it's important to follow the directions of the harness you purchase and contact them for guidance on details that aren't specifically spelled out in their instructions.
That's the first time I've heard or read someone preferring a 5 point over a 6 point and saying the 5 point was more comfortable and the 6 point was the harness that was "grabbing stuff".Personally, I prefer the 5 point harness. 6 point is very messy, takes a long time to get together, and grabs in all sorts of places. :shocked:
