Aero-wizards,

I'm pretty sure the idea here is for the rear edge of spoiler to meet the template curve. Right?

How about the slope of the spoiler, and it's front-to-rear dimension? Is any part of the spoiler that is forward of the template mostly inert, with little or no effect? Or is it helpful to extend it forward to or near the rear glass - that way very little air will flow into the cavity below the spoiler.

Going past the template line would be bad, right? Tuft testing should show turbulence there??

And, how about sloping it downwards? I think on a "normal" spoiler, that would cause unwanted lift . BUT if the forward edge is at or near the glass, wouldn't a downward rear slope help the flow reattach more smoothly?

Thanks!!
