On that first picture, does the side mount extend up into the seatbelt hole? if so you prob need to chop it off, so the seatbelt doesn't rub on it. Otherwise looks good

I think your shoulder belts need to wrap back through the adjuster plates one more time. Looks to me like they're just run through once and then fed back through the harness bar loops. If so, they'll simply slide apart in a wreck.

Good to see someone asking these important questions. Props to you 
. It looks like you might need to tighten the sub belts and lower the cam position so the lap belts are more on your pelvic bones and the cam is about 3" below your belly button. But it's hard to tell from just a photo. Just make sure your lap belts are snug on your bones and not riding too high toward your stomach.
Also, those seat brackets are so so. The Hardbar style brackets are much stronger and probably safer.

As Bill said - Sub Belts.
Sub belt length is what locates the cam lock.
I've seen guys get a little sick to their stomach with the cam lock where you currently have it.

I agree with the camlock position needing to be lower. The lapbelt needs to ride lower on the hips.
Also agree with Matt on finishing the wrap on the harness bar. I would consider locating the straps on the harness bar somehow so that they do not slide sideways.
Also I would like to see the harness bar a bit lower but not much you can do about that.
As far as the lapbelt mounting points, you might consider running a piece of flat-stock between them.

I don't like the lap belt mounts.
You compromised the seat mount by drilling those holes, in turn your lap belts aren't really mounted to anything solid.
The sub belts need to be triple wrapped.

Yeah, I'm really not a fan of those seat brackets. I had similar ones in my old C5 and they were pretty flimsy. They have much better brackets with holes on the sides that you can attach the eye bolts that would be much stronger and safer.
What fastfatboy said is true, you drilled holes in the part of the bracket that is supporting the seat and connecting it to the car, weakening that support.

I have the Hardbar lap belt mount, also well built.
He ruined that seat mount, I would throw it in the trash...I would never trust my life with it now.

You should use the belt mount on the side of the seat mount for the harness lap belt. You have the belt mounted too far back and it isn't at the proper angle to your body and isn't entering the seat pass through properly. You do not want any folds in the lap belt as shown in your picture. Folds in the seat belt were one of the contributing factors in Dale Earnhardt's death. His lap belt tore in two right where there was a fold as it came through the side of the seat. A fold reduces the belt strength to the largest part of the belt that isn't folded. In your picture it looks like that is only 50% of the belt which means the belt strength is reduced by 50%. Installing your lap belts on the side mount so they can swivel will get rid of the belt fold. It also moves the end away from the seat since it looks like the belt bends around the seat back too much. You want that belt path straight from the mount to your pelvis.
The lap belt should fit across your pelvis not your abdomen. It looks like your lap belt is riding too high which is why the cam lock looks too high.
Send an email to the guys at HMS Motorsports in Mooresville, NC including your pictures and get their advice on proper fitment of the belts. They know what they are talking about in this area. They outfit all of the NASCAR Cup Teams with seats, harnesses and helmets. The new NASCAR seat has provisions for a 9 point harness which is all contained in the seat. HMS gets around $8K for each of the seats. If they tell you what you have is safe it is safe. I was just out to their place yesterday getting feedback on what I should do with my new Z. They are heading to PRI so may not be available to answer right away.

This thread is good. I'm planning on ordering seats, harness's, brackets, and ect here in the next few months.
The many threads on the buttonwillow incident redtopz mentioned has me rethinking my seat choice. According to what I'm reading, even a hans device doesn't protect the neck against a direct side impact. I think I'm going to spend the extra couple of hundred dollars on a seat with a good head restraint. Looking at the cobra evolution seat because the cobra seats fit me well and I like the open head restraint that provides adequate vision. I only put a few thousand street miles a year on my car but I feel with that seat I would have plenty of vision.

I don't know how you would correct it.... But you harness bar looks like it is too high compared to your shoulders. It I remember correctly Scroth recommends the shoulder straps be mounted horizontal or slightly below your shoulders. When the straps are mounted higher than your shoulders you can move too far vertically in a roll over.

The Tech Spec (SCCA) is actually straight back to 20 degrees lower than your shoulders (bar height).
