Sub mounts like that are great for those with street cars wanting to run multi point belts.

If you are actually racing PCA Club Race rules state: "Harnesses cannot be mounted to the seat or seat rail. Mounting must be to the chassis backed by large diameter washers (if stock mounts are not used) or to the roll bar."

NASA doesn't seem to have that particular requirement on harness mounting, but they do reiterate: "Large diameter mounting washers should be used to spread the load. Bolting through floor panels etc. is not acceptable without required washers."
