Roof Rails ?

[stratman59]

Jonny,

I did a google search on roof rails and don't remember the exact site.
I think it was Robert Yates Racing doing wind tunnel on 1/2" and the 3/4" rails.
The 1/2" had less drag but the 3/4" was bettr at keeping the  car on the ground.
I thought the same thing as you.

Charles,

I think I'm right about the Yates story on roof rails. I read so much on it that day.
You know i have CRS.
Just what i remember and i save it on my old computer but will have to get it back out to see.

I have not read the Yates information regarding the drag imposed by roof rails but remember their function is to "trip" the air when your car is side ways to reduce the lift on the roof panel caused when the air it traveling across it side ways, helps keep you on the ground so I would certainly go with the 3/4 inch regardless of the probably small additional drag they may impose.

I've seen a couple cars where they come from beneath the roof surface.  No flange (?) sitting on the inside or outside.  Sure looks cool and gives a bigger surface on both sides, but is a lot harder to install.
