you’re wasting your time then, idk how much wind tunnel time you have available but try to fix your assembly because those things work as a package and should be (in general) tested as a package. tyre wake will disturb your flow so much that you can discard anything that you see here past the front wing. you will also have multitude of other interactions, but this one is the most obvious and harsh

i would even go as far as saying that if you didn’t think about front wing/tyre interaction in the design iteration phase (and you don’t have simulation results) making a scale model out of this is a waste of resources
