Update 03/10/05
At this point I decided to do some slight modifications to the exterior of the WRX.
I am going to install two products from APR Performance.
They are a CF Wind Splitter, and a CF GTC-200 Spoiler.
Here are some pics of the Splitter.

The mounting hardware and support rods.
And a close up of the APR logo and the Dry Carbon weave. 
Should be a fun install.
Now to the GTC-200 Adjustable wing.
This is another APR Performance part, and it is a very sweet piece of hardware.

Here are some shots of it at various assembly points.


My only problem with it so far is that the right side mount cannot bolt flush against the wing. 
It looks like the insert in the wing was not installed in the right location.
Hopefully this will be the only problem with this piece.
