So if I think back to 02 when I went to my first Daytona 24 I can remember (and I have pictures) of the race cars with the big flat wings, with two supports underneath propping them up.

Now, when we look at race cars, the supports are IN FRONT of the wing and then sort of gooseneck over the front to attach to the top.

WHY?

What benefit was found in that design?

Im not debating it, Im just genuinely curious

Here's a pretty good primer to get started with:

The short answer is that it is more difficult to keep air attached smoothly to the bottom of the wing than the top, and this is pretty instinctive when you think about trying to push air vs. pull it. By putting the mounts on the bottom, they can trip up this senstive airflow and cause it to lose effectiveness more easily than mounting on top.
