Ever heard of this mod? Anybody did something like that?

I want to install a belly pan on my 99 Acura EL (same as Civic Ex sedan in US) and should this mod be worth, it would have to be installed before the undertray.

Facts and opinions will all be welcomed.

There are no low-drag cars that use it.My opinion is to ignore it.For any infinitesimal gain you might achieve,it would cost you a fortune to develop it.
