My video on bellypans (and be warned, I don't like coroplast):

If you want to use it for test purposes, at least wrap the edges with your favorite tape to seal the corrugations.

Thanks for the tips guys! Julian, that is an excellent video!
The coroplast is definitely short term for testing, or at least until I can get the funds to use some sort of sheet metal. I'll be sure to seal the sides when I'm done fitting it.

A lower rolling resistance is often underestimated, but it makes a significant difference, especialy in heavier vehicles.

Holy ****, that underbody looks like an aerodynamic nightmake in stock configuration.

Maybe also consider a different vehicle for daily driving, yours will never be efficient.

I have thought about putting some LRR tires on my old rims and saving these snow tires for... snow. Just haven't pulled the trigger yet. My daily driver is actually my Corolla. My problem, though is that the car is too small for me and is physically hurting me so I need to start driving this, hence the need to improve the MPGs. Back when I was driving hundreds of miles a day, I was using the Corolla, but now that I'm down to about 40 a day I need to bite the economy bullet to save my health!

Thanks for the tips! At this point getting the proper support is my biggest issue...
