Well after inquiring what info is required for an engineering report on my roll cage, the tech chair answered
"The SCTA does not have a design requirement for the cage structure and no cage structure can be considered safe.
The rules only give minimum requirements for material and sizes for the tubing. All cages where the hoop tubes do not run continuous to the bottom rail must have at a minimum 5 tubes attaching to the shoulder bar.
This is the requirements of the rules and has nothing to do with the strength of the design. Showing with analysis that the cage design is strong is not required as there is no rule to compare it to."
So I guess hacking into my cage and adding an additional bar that adds little to strength or safety... but another bar to be in rule compliance is my option. I thought I was in compliance with the rules with 6 total attachments but I only have 4 attached to the shoulder bar... so they say I need 5 since my front bar does not run continuously to the bottom frame rail.
So I started doing that... it is a PITA but I plan to keep playing in their sandbox...
