Do I read that right? An SFI 16.1 can be used with any head restraint, SFI 16.5 I'm limited to only HANS?
Yep,
16.1 is the standard 3" belt. 16.5" are "Hans specific" and have 2" wide section where the ride over the HANS. Those belts are only allowed if a HANS is used. The 3" can be used with either HANS or not. I use 3" belt. I also got ones with FIA approval. The reason is that SFI belts are good for only 2 years before the "expire". If they are also FIA rated then you get to used them for 5 years. Most belts are good for 5-10 years if you treat them right so gettings with an FIA tag gets you alot more useful life from them. I spent $300 on a set of Schroth FIA belts a few years ago. Expensive belts, but very very nice. When these expire at the end of next year I will probably get another set of these belts.
