I have some ideas I'll post later, I've been messing with the Flow Illustrator and I have to say I'm not encouraged. It seems like the roundness or the roof is pulling down on the air pretty hard, and the roof spoiler isn't big enough to be effective and I have it out to about 10" now. I didn't think a half Kamm back would be needed. And, the big wing located at the base of the wind screen seems to smooth things out, however, there is still the issue of the air dropping too quickly and I believe it is creating a large low pressure area.

BTW: In researching the big wing Idea, I came across that Ernie Rogers guy, he's all over the place on his numbers, look into it, he has like 4-5 things out there and they all say something different, makes me a little worried.

The little ebay prefab roof spoiler would be I think worthless.

I'll put up a bunch of stuff soon.
