Yeah, I'm paranoid, so I'd do the panels in plastic (which are still dangerous at speed), but I'm not worried about orange4boy's design. All told, I see 6 bolts holding that down.

They are rather scimitar like now that you mention it.

Actually, one of the reasons I am using steel and aluminium as a base for my mods, other than looks, is strength. Everything is tapped, threaded and lock-washered. My Dad is a little more cavalier with these sorts of things and it always made me nervous so I'm super careful about things like proper tie down straps etc.

I always cringe when I see someone driving with ten foot wood mouldings sticking out a window, or someone on the highway with a mattress tied onto the roof with strings going through the windows, one hand on the steering wheel, one hand attempting to hold down the mattress as it tries to achieve flight. Funny, now that I think about it, it always seems to be metro drivers.

Previa side shots coming soon...

I'm contemplating a 75% detachable boattail, but I can't devote the time to it right now and I'm going to start with the most practical step first: a kammback that does not require mounting any taillights.

I may not be able to resist the boattail for too long with all this encouragement/egging on.

On the other hand, if I use it as a marketing tool with my logo on it I may be able to convince my lady to let me have at it. The question is would it be good or bad PR? The media likes to take the piss out of anyone doing their own thing. Canadians can be daisy cutters.

Tuft Testing Kammback

Finally I had a chance to try out the angle of the kammback. It's at about 15 degrees in the picture. There was no flow separation at that angle. tufts were flat and pretty motionless. I tried it at more like 22 degrees and the tufts didn't seem to lift, but they wiggled side to side a bit. Hard to tell for sure without seeing from the side.



I think I will leave it at 15 degrees which looks better, is guaranteed attached flow and leaves me some rear view. I may redo the videos tomorrow.

Here is the video at 22 degrees for what it's worth:

Nice!! That's another good side of clear Kammbacks: you don't need to attach the camera on the outside
