How safe is this method of mounting 4 point harness?

There are 2 bolt holes behind the plastic covers that are meant for seatbelts in the rear of EDM/JDM cars wich had OEM 3 point seatbelt options.
But how safe is it to bolt a bar in between those points?
I now have my belts mounted on the point where EDM cars have the OEM backseat seatbelts,....but the mounting is a few degrees off centre of the seat.
This might be a good alternative....

Keyword here is spine compression. What you have going is fine for auto-x where you don't plan to hit anything. Though I would never get in that car like that. And a strut tower bar is not a structual member, those bolts are tiny and weak, and the bar is even weaker when being pulled in a fore aft motion since it was never designed for this.

Would you be willing to tow your car with that bar? Could you jump on it without destroying it? If the answer is no, don't mount a harness to it.
cant you put the harness where the rear seatbelts attatch to???
i mean that is a stong place
and if you have sparcos or somthin in your car you dont have to worry about spine compression
am i right??
