Shelf Spoiler ...
 

Hello -

What do you think of this (Ikea? :p ) shelf-spoiler? :

It *appears* to be about 14.7 degrees from rear-window top to the end of the shelf, which would be good for aero (right!?!?!?).

Sometimes you get lucky?

I have envisioned a much nicer looking version of this many times...
maybe he's an aero savant.

Of course I can't find a pic now but I remember browsing through a Corvette parts catalog back in the early 80's they had a rear wing that had two little indents so you could set your drink down near the outside corners. LOL Wish I could find that picture.

Did it look anything like this one?

OMG that is soooo cooool! You can see it's a trick pic from the safety pucks(?) he put between the legs and the paint.

He should have done more typical pictures "in the world" for laughs.

I thought that shelf was for downforce, to keep the trunk from opening while driving?

And of course you have somewhere to do your ironing when you stop.

It's an aero device / it's a diaper changing station!

I like them.They push the body closer to the streamline flow pathway.
The car pictured could also use a shelf mid-way up the backlight and also extending back until it intersected the imaginary streamline flow pathway.Like Ford kinda did with the Sierra concept and Merkur XR4Ti.
They create the locked-vortex that the outer flow skips over as if it were a solid surface.

What about a little lip spoiler on the roof? Would that do anything or just look goofy?
