I'm soon going with the Full blown turbo kit, and on my BRZ I am planning on cutting the moustache/mouthpiece completely out to open up the front grill area for more airflow.
I found this part that I am planning on replacing the front cross beam with.
Not sure if it is as strong as the OEM brace, but it's something.
