Ok a few questions first. Where do you get a hood like that and do they make any Fiberglass or CF ones? and second wvat rims are those on tve first pic with the red lip and third what lip is that on the GTS with the lights flipped up?
I know I am a little late on this thread, but why all the fuss over fiberglass hood scoops?
If you want to do this yourself, make one out of aluminum sheet metal!
$15 or less in metal + a cheap bending brake ($40 or so at Harbor Freight I think it's called in the states - an analog of Princess Auto in Canada.) and a pop riveting tool + rivets will yield you a custom looking hood scoop that's functional (though you might want to body fill or something the cracks to avoid turbulence from air around them) and totally doable.
Cut a hole in the hood for it, make a nice cardboard cutout pattern and trace on the metal. Be sure to leave tabs to fold the metal into shape and rivet it together as you like. You can make it totally functional and it will look cool. You can further fill it up to shape it a bit and paint it along with the hood if you'd like (I prefer bare sheet metal myself, however)
You could even go as far as to create a hinged butterfly flap in the intake hole that is driven by a servo and relay sensor from your throttle cable (think throttle position sensor from a nitrous kit - wire it up so instead it triggers your flap to open at WOT)...or if you can think of a way to bridge the cable so it's totally mechanical, that would work too I'm sure.
Sheet metal is real easy fun stuff to work with. It's cheap, and Aluminum doesn't rust. You could polish it to a beautiful shine if you choose not to paint it, and you don't need a welding machine to put it together in cases like this.
Good luck, and post some pics if you make your own scoop!
