Coroplast Front Drop Chin Spoiler
 

Got a couple 4 foot by 8 foot pieces of coroplast. Finally got to install my front drop chin spoiler on my Escort. Only took about an hour to complete and I'm hoping to improve my MPG some. Already had EPDM wrapped around the lower front bumper. Think I'll need to re-inforce the spoiler at the bottom with some thin metal though. Plan on building a belly pan with the extra coroplast, some better wheel covers and possibly a rear deckled spoiler. Where should I go next to see maximum gain?

And here are the wheel covers:

That chin spoiler looks really nice. I'm thinking of doing something exactly like this on my truck in the near future. I could see you needing to reinforce some, wind can do some seriously pushing at 70mph.

Reminds me of my first attempt... ;)

Yer definitely gonna need to build up some support on the bottom. That Coroplast is gonna fold quicker than a beginner at Poker. :(

Looks like you have or soon will have picked most of the low hanging fruit.

Unless you put on a full boattail or a serious Kamm-back, you've done the big aerodynamic mods.

(Passenger) mirror delete, if it's legal ?
Deflectors in front of the rear wheels ?
Deflector in front of the windshield wipers ?
Boattails aft of the wheels ?

Not sure if I'd call it low hanging fruit - but a smooth belly pan seems to be a good thing. See the suggested mods list in post above.

So far as I understand, a belly pan is usually done without a big front snow-pusher as you so excellently built.

Yes! A Kamm back is exactly what I had in mind. Keep looking at the back of the car wondering how to go about doing it. Already have the passenger side windshield wiper off. Think I'll start looking for a convex mirror to mount inside on the passenger side so I can delete the outside one.

If you'll be doing a tail it's extremely important to have the best quality airflow getting to it.
Looking at your photos,it looks like a rocker panel cleanup,flush with the outside of the tires and a full rear wheel skirt would help.
'basjoosing' the front wheel openings as on the AeroCivic would be good.
As to the tail itself,a receiver-style trailer hitch is a great way to go.You can already purchase sturdy,lightweight cargo carriers which just slide into and pin to the hitch,which becomes a perfect platform from which to fashion the tail.
A trailer light kit, electric umbilical ,and license plate relocate complete your legal requirements and safety.
If you want to go extreme,a trailer will allow a canoe full of savings.Parking challenges will reserve this one exclusively for the longer forays out to Wally World.

Something else you might want to consider fer that open slot in the cover...building a duct between that and the radiator so the airflow is smooth and direct. You might want to round the edges at the opening... ;)
