You can add some more rigidity by having us add a B pillar connection between the shoulder harness mount and the bar. Then it would essentially have the same strength as a roll cage from the hoop side.
The rear extensions go to the wheel wells on your car (Autopower) which is actually acceptable to SCCA as part of their cage requirements. You do have a little bit of flex from these wheel well attachments, but not as much as you would think
As your car is getting more modifications, you may want to consider adding bars from the main hoop to the rear shock bridge; although this is somewhat radical with cutting thru the bulkhead to do so. Another mod would be to install a X brace on the rear section to the hoop. This is not going to be fun as access with carpeting and a welded in main hoop is difficult
So what I have is still better than not having anything? OK. I wasn't certain, and honestly, had forgotten the vertical supports.

I'd like to see the other welding you mentioned if you have photos, or when I stop by for the suspension work.

Thanks, Dave.
