I have a few aero questions.

So I finally did the aero template and these were the results





So I have a few questions about that and some that are unrelated. Anyway here they are, first did I use the template correctly?

Also is the spoiler going to affect anything? I was wondering because it seems like the back end is bad enough that it shouldn't make a difference. I also don't want to take it off because I think it would make a really good mount for a kammback idea I have.

Now the unrelated questions.

Is it better aerodynamically to have a grille block in front of a plastic mesh kind of grille or does it not make a difference either way?

For wheel covers would having them on the inside of the wheels work as well as on the outside like you usually see?

And finally (for now) is smoothing out the back end of a car (like in the area with the spare tire well on mine beneficial without a full belly pan?
