Pickup air dam - too low? Jeep MJ

Hello all,

I have the opportunity to pick up a fiberglass SCCA-style air dam reproduction from the original mold identical to the below Comanche race truck for my own Comanche, with the thought to improve aero.

Now as I understand it, there can be disadvantages to too large of air dam that extends below the underbody contours/parts. Would the SCCA one significantly hurt the aero/mileage vs. the modified S10 air dam on my rig (image below for comparison of the above, sorry for the shadows), and is this SCCA dam more for downforce than for streamlining?

Additional info: The above home-brew air dam's edges curve around to cover 2/3 of the tire and not completely cover the frontal area of the tire as the SCCA style does. Also, the S10 air dam is vertical; it looks curved back in the image.

Thoughts on this? I'm still new at this, eager to learn.
