Thanks all for your responses thus far! I'll compile some names here shortly.
Just reminder to those of you mentioning the pre-sale, don't forget that price is only good as long as the contest runs, which ends August 7. If you win and have already purchased then I'll refund your money.
Ahhhh fine, if you guys just don't trust me then I'll end the pre-sale pricing on August 9th. That gives you two days to come to grips with the fact that you didn't win and you can still buy the whole thing at the discounted price of $300.
Oh yeah and here's pic of the cross bar setup. This bar is curved in order to offer clearance for drivers who need their seat all the way forward. Had to do this on these pre-production mounts before for the design was 100%. However the production mounts will have 5 slots so you'll be able to move a straight bar (no curve) wherever you need it to be.
What organizations allow mounting sub belts in this way? From my understanding SCCA requires them to be mounted to the floor, not the seat frame - this is consistent with our rules up in Canada as well.

That is a good point. I just checked the NASA CCR and there are no rules as to how one should mount their sub-belts. It suggests thru the floor with washers, but it does not require it. I've also never had anyone check regardless. That said, you raise a good point. Can you tell me what's required for your organization? It would be nothing for me to drill two or four more threaded holes thru the bar, where you could install yet more screws and washers thru the floor if you so desired. You'd just drill clearance holes from inside the car using the sub bar as a template, and add screws and washers thru the bottom of the floor. Piece of cake! I'm doing it!
Edit: Just checked into SCCA. Again, suggestions and not rules as far as I can comprehend. So, then I'll do what I said above. I'll add holes, and make up 2" diameter washers for above and below the floor with Grade 10 bolts. I'll sell this additional anchor kit as an add on for those who feel it's necessary or where required. Thanks again for the tip!

I am the one who specifically made the harness mounting bar request if I am not mistaken. I have not liked the floor mounting methods on most Corvettes. In my GT2 car I copied FatBillyBob and had some cage mounted seat and harness mounts welded in. For my Spec Corvette I made the request as Mark was designing the seat mounts. I think this is a super clean set-up and gets past the questionable hole drilling in the floor of the Corvettes. At 50+ G force I don't want to find out how strong the flimsy floor and backing plates are. Perhaps I am wrong, but I figure GM did plently of crash testing with their seat mounts and belts.
BTW - Here is what I cut and pasted from the SCCA GCR - Each seat (lap) and shoulder belt of the harness (5, 6, or 7 points) shall have an individual mounting point (i.e. 2 for seat belt and 2 for shoulder belt minimum). 6 or 7 point system anti-submarine straps may share a mounting point with one or both seat (lap) belt(s). The minimum acceptable bolts used in the mounting of all belts and harnesses is SAE Grade 5/Metric 8.8. Mounting hardware, including eye bolts, as provided by the belt manufacturer, may also be used for mounting belts and harnesses. Where possible, seat belt, shoulder harness, and anti-submarine strap(s) should be mounted to the roll structure or frame of the car. Where this is not possible, large diameter mounting washers or equivalent should be used to spread the load. Bolting through aluminum floor panels, etc., is not acceptable. Holes in the roll cage to accommodate the installation of the harness must be bushed and welded completely.
