A) go around the seat but rather through it
B) should not be bolted to the frame and any belt angle past 110 degrees is unsafe (as in the belt passes through the seat then angles around the shoulders into the lap of the person)
C) have the bracket bolted more than 30 degrees of angle from the location of the belt going off the bracket.
These setups fail to meet B and possibly C but I cannot see the brackets.

These belts keep you from going forward in a crash if you crashed like this the unibody frame plus the way your body would move would crush your spine. it's been proven before in many tests and there is an article in PAS magazine about it maybe 1 year back.

Seat belt mounting, I believe there should be a cross bar in the roll cage directly behind the drivers seat at the hight of the holes in the seat for the seat belt and the shoulder straps for the seat belts to be attached to that bar. A few years ago a race car I was pit crewing on had a large impact into the side of a bridge and the impact was enough to tear the seat mounts out of the floor and because the seat belts were mounted a distance away from the seat the seat was flicked lick a whip and the driver suffered massive head injuries when his helmet was smashed against the pasenger side of the cars main roll hoop.
The shorter and the straighter the belts the less stretch and whip can be generated.
I also believe the top of the seat should be rubber mounted to the cross over hoop so that in a rear end inpact there is at least something to take the forces on the top of the seat to prevent it getting torn out of the floor and whipping backwards. This did happen to another driver I worked with and he died from his injuries in that crash.

These should be illegal harness monuts but I know that's an official D1 car so I guess they let it slide (no pun intended) or maybe the Japanese are less concerned about the drivers dying.

Floor mounting is ok. Mounting the belt on the strutbar is ok as long as the angle is 10 or more degrees. OEM FD strutbar wont do.
But i can agree that those angles look a little extreme. I wouldent mount it that way. FIA recommed no more that 45 degree, but at least 10.
