On my car the front wing itself is not so much the problem, as the front wheel suspension members. They all have separation on the top and are the real cause of cptot loss of the cooling air.
if only one was allowed to angle these a couple of degrees...
It happens the same with my car. Also to lower the sospensions (maybe 50mm) would help.

So, the last round is upon us.... and I never really felt like I got anywhere with the car... too much time trying to sort out that damn cooling! Indeed, the biggest change on this last version was also to the sidepods... the "top vents" are now removed again, and the internal "double-decker" ducts (maybe the eagle-eyed amongst you spotted them last time) in each duct are now adjusted, and visible through the cut outs in the side of the sidepods...

The only other change is to the diffuser profile... now featuring two "expansion zones" as spotted on some of the front runners...

The wings are clearly at least 30% down on downforce compared to the front runners... but I didn't change the front because at the moment the COP is too far forward, and I didn't change the rear because I am hoping the sidepod change will improve the rear wing downforce without requiring any changes to the wing itself.... time will tell...

What's the purpose of the double decker ducts?

Well it’s really just the result of adding a single long guide vane in the duct behind the heat exchanger... I think it looks like you had one there for COTA too (?), but mine is much longer, and inside a longer sidepod... so it effectively splits the duct into upper and lower portions... the reason for the longer sidepod is to try and limit the interaction with the rear wing...
