See....now you're thinking. Glass is so heavy....that hood is already too weighty. Aluminum would be so nice. Look at the front hard. You can visualize the airflow (at least I can) A WRX scoop is only gonna work, if it's at least six or seven inches forward of it's usual position. Looks kinda weird. The ducts works better, but don't look a dramatic, a big plus is, they can be turned to work as extractors as well. Carbon is fine, you just gotta paint it ( unless you are GM, and can afford the 2000 a gallon for the special clear used on the ZR1 carbon) Someone did carbon fiber inserts a while back, with and without WRX scoop. It was pretty much a mixed ending, but the ones I saw, looked good on my computer screen. Those molds already exist out there somewhere.
