Looking at the diffuser wall stabilizing rod. Where does it attach to? Surely it isn't doing anything sitting in the wall only and not extending up? Or is it just a strip of stronger carbon/titanium (idc what they are using) that they are running inside the carbon.
There's no attachment as such to effectively brace against another structure.
Essentially it's a tube built into that sidewall to stop it flexing ftom top to bottom, the principal "stress" load is cantilevered vertically off the top plane of diffuser component.
Integral "tubes" like this are often used to enhance structural support when no immediate other attachment can be logically employed. Made by lamination in giving that detail, often with a foam former or similar put in place to give that integration while laying up the structure in manufacture.
It will allow a much thinner and lighter material in that wall overall, with this detail to mitigate against that lightweight structure bending how they don't want it to.
In comparison, a front wing structure will incorporate both hollow sections and simple curved planes that do the same but as part of their curved design incorporating this property. That rear diffuser wall, being essentially flat, doesn't have that as native design and so needs this additional feature to complete.
