Some superkarts have more balanced aero than others. In Racecar Engineering, Simon Mcbeath once tested two superkarts
in a windtunnel. One produced a good bit more downforce than the other. The one with more downforce also had a better aero balance. The one with much less downforce, produced it all at the rear, similar to your test.
In fact, I got the help from Simon. So, perhaps you're talking about the same data that he provided me.
It's not too much, but for me it's quite useful because I really needed a baseline to work with.
Later on, I will post images showing at what point I'm on my simulations and what problems do I have to face. Beucause know I'm in the point to add the endplates and 2 beam wings (because the central part needs to be free). And it is quite difficult to find the optimal configuration within the dimensions that says the rules.
With all the assembly, if I achieve more downforce, but the drag it is also increased and the lift to drag ratio (L/D) is more or less the same or a bit lower than a single wing profile with endplates, the final assembly can be considered a good design?
Another point is that my rear wing configuration is in free stream air. Whereas with the "external" drag added by the driver over the airflow over the rear wing, I think that the levels that I achieved will decrease.
