That looks promising, reminds me of my Syms carbon wing for the STI and the current Oakley design porsche wing...
I see the square cutout of the piece you gotta remove to get to the adjustment screws, so that answers that question...
I gotta say the same thing as Seeyabud though... this looks a lot like an amuse wing with the center cut out and angled up a little.
Either way... looks very 1980's LeMans, which is a great thing in my book. Just needa refine it a little and hopefully make the center carbon.
