2. Control arms move up and down, and make drag hanging in the breeze. Since Coroplast is flexible, would it work to tie panels of it to the control arms, that move up and down with the control arms? Such panels could be fixed at their forward (upwind) positions, and their trailing edges be tied to the control arms. Perhaps elastic ties could be used, to stretch a bit as the control arm/Coro fairing move up and down. This would make almost all of the car's underbelly smooth and flat. Properly done, Coro gaps could act as engine heat vents, drawing hot air out of the engine bay by Bernoulli effect, for less cooling drag.

Aluminum meshing would be an excellent idea, there is another user on here with a 2002 Infinit Q45 that is doing the same thing.
In terms of the control arm panels, I am picturing something like this in my head?
I was googling "alumalite," yes it says its very strong, light, and durable, however, the nice thing about coroplast is that its very flexible (and strong, light, and durable). Plus the pricing for a 4'x8'x 0.5" (thick) alumalite sheet is $545
The same size coroplast only costs $20ish.
As another user on this forum said, people always mess around with different build materials on here, but in the end, they all end up using coroplast because its light, flexible, waterproof, durable, and CHEAP.
