My only worry with that is the use of hot glue.
Too many times I have seen that stuff just fall off of whatever it was attached to.
Maybe an epoxy would be better.

ah yes, well the problem with using an epoxy would be that it would be near impossible to get the epoxy off of the car... one of the reasons we are using hotglue is that its easy to scrape off if we make a mistake or a design change... but yes, I see your concern...

That's pretty cool! What were you planning on using to cover them?

FYI, you're going to have turbulent flow at the rear of the skirt where it curves in to meet the lower bumper cover. You can clearly see this in the tuft test vid I made of my car's rear skirt: http://ecomodder.com/forum/showthrea...etro-3692.html

If you want to take it to the next level, "blend" the rear of the skirt into the lower bumper. It'll make a small, but real improvement.

I see the video that you have up, but you don't have any evidence that fairing would actually improve the situation, but from what I see, it looks like I could just add that after the skirt is done.

Question: I have about 3/4 of an inch seperation between the wheel and the metal cage, should I have done more, or less? What did you do?

You're right - I haven't tuft tested the before/after with the additional "fairing" aft of the skirt. I'm just making what I think it is a pretty safe assumption.

I think 3/4 inch is pretty good. You want the skirts as tight to the wheel as practical. Mine are about the same (actually the driver's side is tighter than the passenger side one, just from slight differences in my construction).

You could try something similar that would instead of creating down force push the air coming out of that indent away from the side of the car.

I don't quite understand what you're proposing... could you draw something or possibly point to something somehow? or otherwise elaborate?

bad idea, pushing air away from the side of the car promotes turbulent flow... adn increases drag. this is especially bad at the front of the car because the vortex of turbulent air will only get bigger as it goes to the back of the car.

Here is what Binger is talking about, the doodads on the sides :



They look cool, but I agree with Tourigjm that they are not appropriate for MPG.
