Is the schroth Profi II 6 point harness with the 2 inch lap belts SCCA legal? If so does anyone have any experience with it? Is it better than the 3 inch lap belts?

I just replaced an older set of Schroth belts with 3 inch lap belts with new 2 inch belts. They are big improvement. More comfortable. Easier to get tight.

Dusty, did you run your 6-point sub straps through the same holes in the seat that the lap belts go through, and then snap them into the lap belt eyelets? Is that legal?

Legal and often preferred.

So you're sitting on the sub straps? Why is this preferred?

I have run 6-point belts both ways. Both have their pros and cons. I understand the rationale behind 7-point belts now. I preferred the subs going to the lap belt anchors because they really hold you very well to the seat. The only thing that's a little weird is that when braking hard (and I imagine in head-on collision) it feels like they lift you a bit...or allow you to lift rather. The 6 point config attached to the floor doesn't feel as secure but the lap stays better located. I think a 7-point with subs going to lap belt anchors and a single anchor doing under the seat would be best.
Finally, the biggest problem for me was that my seat was mounted directly to the floor so it was very difficult to mount anchors under the seat. Some manufacturers tell you to mount the subs to the floor only. IIRC that is why I had my last set mounted like that, they were Schroth Profi-II also.

I don't really like that idea personally. If you're upside down with both straps going through the lap belt holes, it seems to mek that both the sub and lap belts can rotate upwards, loosening the shoulder belts and the roof is a bit close to your head for that.

Question, I tried to mount the snap brackets for the lap belts and the sub belts to the same eye-hole bolt, but you can't fit two snap brackets on the same eye-hole, which came with the schroth kit. Can I get ones with bigger holes anywhere?

If you mount both the lap belts and sub straps to the same location what hardware should be used as it doesn't seem to allow you to mount two snap brackets to one eye-hole?

Schroth sub belts should go to the floor. They have to be very short. HMS Motorsport can help make up very short sub straps. The intent of the sub belt is to hold the lap belt in position so it cannot ride up. As mentioned earlier the sub going to the lap belt mounting point does not hold you in place as well during a roll over.

Yeah I actually purchased the belts from HMS and they are sending me new hardware to hard mount them under the seat through the floor (for free might I add, thanks guys). Let's hope I can get it all done in time for Friday's tech inspection at the NJMP Driver School.

Use the story and picture on page 43 and 44 of http://www.hmsmotorsport.com/docs/Competition_Instructions.pdf for mounting the sub belts. A real pain to get set up. Watch the way the webbing is routed and don't be afraid to send pictures and ask questions of the HMS guys if it does not make sense when you are swearing at the car doing the install.
I had to open up the seat hole to not interfere with the straps. Don't forget to make sure there are no sharp edges where the belts go through the seat. I also bought their under-floor mounting pads.

the 2 inch belt is specific to the Hans device. there is a warning label on the shoulder harness

The 2" lap belts have nothing to do with the HANS. The narrows shoulder harnesses are HANS specific.

I just installed those belts in my car. After using them for the weekend I will never go back. No more wrestling around trying to get in your car. The lap belts and shoulder straps can be tightened with 2 fingers and released just as easy. The other benefit is that you can get the belts very tight if you like. The belts are a bit pricy but well worth the money.

Whoops, my mistake. I re read it and missed the lap part. I do have the 2 inch Profi on all 6 straps and like it for the adjustment ease. Promise I will read more carefully in the future
