I made my own custom splitter and used the blowfish racing splitter bracket/tow hook combo. modded the lower grill to allow the tow hook and splitter struts plenty of room. I figured its just a normal lower grill like on any gt or v6 so I can always replace it later if I return the car back to stock.
I was looking to do this as well, but I have seen a few in person at car shows and they look to tacked on for my taste. If I was going to track my car and needed it that would be one thing. But I was going to do it for looks only so I decided no go...
