Six-Point's with OEM seats?
 

So are there any opinions about using 5 or 6 point harnesses with the stock seats?

:iono:

1) do not run sub belts around the front of the bottom cushion ; follow the installation instructions which will require a sub strap hole in the bottom cushion and sub strap bar under it

2) I'd go with Schroth ASM 4-points. This is what they used in the Celebrity Challenge FRSs at Long Beach

Agreed and I would not hesitate to use the Schroth ASM belts. Something to consider with the Schroth ASM (anti-submarine) belts:

Imagine the testing and "proof of concept" required for a product like that? A product that "old school racers" would naturally be skeptical of, and that Dewey, Skrewem & Howe would be more than happy to poke holes in?

Talk about an industry sensitive to litigation... it's a no-brainer to use them if the application works.

Just my opinion and not a guarantee of fitment or suitability for your intended application, etc. etc. etc... of course. :)

Are we talking with or without a roll bar/cage?

with a 4 point cage

...of course! ;)

Then I concur with what Sleepless said.
