Seat belts

[ike84]

Ok, I need insight here.

For whatever reason, I've become paranoid that my 21 year old seatbelts aren't up to snuff. So I'm looking at options for replacement.

I realize the discussion of 3 pt, 4 pt, 5 pt, 6 pt is a long one and I don't want to start a debate about the pros and cons of each. What I'm really looking for is what is the safest option for a road car that sees WOT and a lot of curves.


OEM stuff is all 3 pt and allowed in a lot of racing applications.... But there is no safety rating on this stuff for racing, no age limits, and Porsche doesn't use high grade bolts for our seats or seat belt receptacle (hell, the receptacle is bolted to the seat rail which is an absolute no in most organizations!)

There are aftermarket 3 pt replacements for sale from China that are certified to EU regulations but not NHTSA or DOT. What's the deal with these? I'm skeptical.

Has anyone ever used the "3 pt" racing style (essentially a 4 pt where the shoulder straps converge)? It seems like these are gonna have the same issue as 4 point belts - submarining.

BUT - fia now certifies 4 pt harnesses?!?! What is up with that? I know schroth makes the 4 pt ASM systems that are DOT approved (and stupid expensive!) But I was surprised to find 4 pt cam lock models from sparco in their "competition" line that are FIA certified. Are we not worried about submarining any more?

Currently all my driving is street driving and I don't have a full cage, so I know that 5 and 6 point harness are really out of the question for my application. Maybe one day when my free time doesn't always come after the kids are in bed lol...

Anyway, all thoughts and experience are welcome and appreciated
