Full under body panel for 10% fuel efficiency gain. (about 20% aero drag reduction)

There's no way this will work. The increased drag of the attached jackstands on the ground will more than compensate for the lower drag of the belly pan.

Tom, you so FUNNY!!!

Hey hey! Don't 'jack (stand)' this thread!

My biggest concern (because I have so much rus- err - weight reduction) is that it would hold in excess moisture, thus leading to extra weight reduction.

I suppose if you triple-sprayed it before putting this belly on, it might not matter as much.

Nice. Yes, before and after numbers anxiously awaiting.

i've thought about this also. not the full belly pan but judiciously placed small foils/covers over or in front of suspension components in the airstream. potential problems i'd think about with the full pan treatment: engine cooling. where does the air entering the radiator now exit? becoming airborn. the right speed, the low weight, the gust of wind. you've surely seen a news clip of a hydroplane boat flipping?

How close is that to touching your exhaust? Your not worried about it melting through are you?

[Bert]

I hope you can figure out a way to keep good records so as to compare before and after. Great idea.
You might chuckle about this but dimples on golf balls create a boundary air layer that allows for more efficient travel. I wonder if thoroughly working a Festy over with a ball peen hammer would make it more fuel efficient.

Awesome! I've always wanted to do this
