Under the front on mine(style is a little different on the 05?)...the OEM dam is about 5" above the general undercarriage. This area under the engine and trans allows air to directly hit the oil pan and trans pan and assorted "stuff"...likely causing a lot of turbulence to the rear. Once past the engine...things look pretty smooth...except right at the back near the bumper....but the bumper is above the rest of the undercarriage...so it shouldn't catch air much. *After looking at it again...guess things are pretty sloppy in front of the rear axle too.

Might install some kind of deflector in front of the tires on both sides....thinking of angling them so the air is routed out to the sides.

As far as weight...it isn't real light....maybe 15 lbs or so. But unlike plastic it won't deform with heat....and is strong enough to handle snow...etc. 1/4" plywood might work OK...but it's hard to find it with outdoor type glue.

I'm going to close off the upper opening in the front like you did...and maybe some of the lower area temporarily during the winter.

Actually installed it...no issues on a 65F day with the wood getting too hot near the cat and exhaust. It does decrease the ground clearance by maybe 1/2" or so at the back.
