Stainless Kammback for Previa.
 
Just finished this today. At this point It's still a roof and sides extension but I'm adding bigger panels soon. I can't wait to try it out. I have to find some rubber moulding for the leading edge on the sides where it touches the paint.

The pieces are all totally detachable and no holes were drilled into the body. I used existing bolt holes and bent stainless brackets to attach everything to the back door. I tried to get around 10 degrees slope and will gently curve the panels to get optimum taper. I plan to make the panel over the rear window plexiglas so I will be able to see and do tuft testing easily.

Thats a very nice bit of craftsmanship. Well done. Does it save much fuel? Improve stability?

Here are some more of the brackets.

It was a PITA to get the stainless to bend in just the right shape but nothing a good hammer couldn't sort out.

I'm hoping I won't get any flutter at speed. There is a small gap which will go away when I find a moulding. In the meantime, some foam draft seal should do the trick.

Ollie,

I haven't had a chance to test it yet. Will do soon but probably no a-b-a.:( At least not yet.

I was gonna mention the gap later on, but I was betting you\'re already on it, and you are.

Took the van to town today. Too soon for data but coast down on a regular run was about 5-10kph higher than before.

I did register a lot more LOOKS than before. Does that count for anything? I preached the Ecomodder gospel to a few interested people too.

Fantastic work :thumbup:

I\'m so ashamed with my uglyback... :o

Please, keep us informed with your feelings and your improvements :turtle:

On the road today with the new extensions. Coast down is definitely better. I got up to 120kph in a spot where I usually only hit about 105Kph. Mileage stayed the same but I was using A/C today.:o The egg is a greenhouse crossed with a magnifying glass. Where can I get those mesh seat backs in Vnacouver?

I can\'t wait to add the kamm panels. Wait, what am I doing here typing when I could be modding?
