I've drilled in mine alloy wheels made thread inside and screwed in my aluminium discs.
Here is a video of them on youtube http://www.youtube.com/watch?v=W1dwPQ37FlA

holypaulie - I hope you don't mind I copied your vid post (from http://ecomodder.com/forum/showthrea...eels-7405.html) into this dedicated thread. It's threadworthy on its own!

You don't have a fuel log... what kind of fuel economy are you seeing? What difference from stock?

Nice !!!

Please do let us know what kind of FE changes that you see !

Thanks for posting the video. I love what you have done with the car - great use of the hood vents.

Pretty slick. I was definitely thinking about the front wheel well partial covers/extenders that you have on there. As long as the tire can turn, with suspension compression, they might as well be a mm away from the tire, right?

Hi Paul,

I really like what you've done, too! I'm envious of the color match you have, and your fabrication skills are commendable.

I wonder how the front wheel skirts could be made from (slightly) flexible rubber/plastic?

I'm with the others, the mods look great. Do you have any internal ducting for the cooling system?

Not a problem.
Stock MPG City: 27 Hwy: 35
Present MPG City: 32-35 Hwy: 40-45 at 55-60 mph (hot summer 45-48 MPG)

At the full wheel turn and full suspenion there is about 4 mm clearance. I've never hit my skirt though even at the speed bump.

Here you will find more pictures of my cooling setup http://ecomodder.com/forum/showthrea...nt-6543-2.html

How do you have the rear skirts rigged up? Good stuff!

Thanks
I've cut 1" wide, 1/16" thick and 2" long metal strips and bent them 90* on vise. Next drilled bracket directly to inner edge of wheel well with self-tapping screws. Painted and sealed with waterproof glue. Finally screwed in skirt again with self-tapping screws. There are 4 brackets to hold tight and safe wheel skirt.

Have you considered adding a small duck-tail spoiler to reattach the flow on the back of the car ?
I notice the hybrid has a small duck-tail spoiler.

Perhaps some tuft testing would be useful.

I was thinking about about it, but I've heard it doesn't make big difference.

There's really not much else you could do without significantly more radical modifications; perhaps the rest of the underside could be smoothed over. Very clean work, I like it better than stock. I'm inspired to try this on my car. Have you tuft-tested your hood vents to see if they work the way they should?
