I've seen a lot of structural modifications done to old Porsche 911's, but never some of the things he is doing. I say BRAVO, good work.
The one issue I didn't see him address is the weak spot in most cars, where the large holes in the side of the car are - called doors. Even more flex is Targa and Convertibles with no top to arch over the doors and complete a box shape.
Normally in so-called full roll cage these issues are addressed.
Falling just short of a full roll cage are rocker panel reinforcements that are often triangular in shape from foot-well zone going upward to middle part of B-pillar.
When a car "folds in half" it is the area around the doors that "give it up" and allow the occupants to be crushed. Stiffing this area stiffens the chassis considerable but comes at the cost of ease of entry and exit.
I can only guess that the author of the videos knows this and is doing modifications that allow a stock look.
