I am sure if you raise the front wing a bit you will enhance the diffuser. This is why I said the diffuser angle is too aggressive. Such shape would work if there was more airflow to it, so I would either make it less aggressive, or raise the front wing
No way keep the front wing as low as possible. Esp. because you have to get more front downforce. One easy fix will be to have the sections infront of the front wheels flat (and as low as possible).
I think it is not as simple as that. In the ground effect area, having a front wing effectively killed airflow to the underbody, and therefore killing downforce (or suction, depeding on how you call it). We don't have an airfoil-type underbody here, but we have a diffuser which is what an airfoil shaped underbody is basically. Try to remove the front wing and you will increase the suction at the diffuser. I don't think this can be questioned, or?
However, it is true that he is lacking front downforce, so by raising the front wing he will most probably lose ground effect on the front wing.
As I said, to improve the diffuser's efficiency, I would either make the diffuser less aggressive, or raise the front wing. Modifications that can easily and quickly be tested by RicME. You can even send me the files and I can simulate them on my computer if it saves you money from using amazon server. With regards to improve front end downforce, Machin posted some solutions to try as well.
Machin is spot on with modifications tho. Try 1 thing at a time!
