My Geo Metro Air Dam Mod - Fuel Economy, Hypermiling, EcoModding News and Forum

I made an Air Dam from a new bug shield that I purchased at the local thrift store. You can see more pictures in My Albums.

What do you think of it?

I think its a smart idea and the clear looks good too. Let us know if you get any increase in FE.

Interesting. I wonder what effect that concave front will do in terms of the possible gains.

Very nice. I like the look of it. Yes, let us know if you get FE from it...

If you take another bumper, cut it in half and flip it upside down, you have a neat custom air dam.............

I have never in my life seen a ricey metro. Congratulations.

the clear dam looks neat - hopefully since you mounted it close to the wheels you won't break it on anything!

I too am interested.

What about closing off some of the air duct for the radiator with clear plastic?

Some of you have commented on the "concave" shape of the dam...I'm thinking that the forward rake will help channel the air to the sides because it also follows the curvature of the bumper. If it were straight across, I'm sure it would create considerable drag. In any event, we shall give 'er a try and see what results it produces. I was just giddy at how well it turned out considering it was meant to be a bug shield for Ford F-250 Super Duty, F-350 Super Duty and Excursion...lol

I really like the clear look too, and plan to do a grill block and make turn signal covers to smooth the bumpers' aerodynamics with similar material. Headlight covers for the "buckets" will be soon coming as well. (still trying to figure out the dim pass light problem, though.)

Thanks for the kind words so far. I took it off because I'm still in the middle of tracking my mileage increase with the new XFi cam grind and don't want it to throw off my calculations(either direction). I have some trimming and rounding of the edges to do yet anyway...

those do function nicely. I used a chunk of rubber conveyor belt with an aluminum 90 for an old subaru. I could bump into things and it let flows more as speed increased. (very tough nylon rubber).I see these custom on many cars. I can't seem to find more of that stuff...what ashame. I'd make another one...
