5 or 6 point seat belts???

[flotowngtm]

I already have the Tillett seats that are Hans compatible and will be getting a harness that's Hans compatible also as I have a bad neck.
Now I am not a racer so I really don't know what the difference is between SFI and FIA ratings. All of the belts that I have been looking at are either or. But what is the difference?
As far as the 5 or 6 point. I have read that a few tracks recommend 6 point belts if the driver is seated up to 30 degrees. But not required. Anyone have any insight to the differences between the 5 and 6 point? Besides the obvious.

The main differences between SFI and FIA ratings is the material used in making the belts. In my opinion the FIA belts are much better and are rated for 5 years service and the SFI are only rated for 3 years service by SFI and SCCA anyway. My favorite belts are Schroth and I am looking at 4 point for street use. The SFI belts seemed to always loosen up durring a race and and the FIA belts never did. SCCA required 6 point harness but I mounted the 2 subs belt at the same location.
