hmm...I was thinking that the splitter might actually work better with that hole/gap there. I figure the air that passes through that hole would provide more downforce rather than not? Since the air would travel along the length of the rest of the CF board, all the way to the black plastic under-tray/cover
Also, I'm finally going to take the splitter for test runs on the track in another week. We'll see if it actually has any performance benefits =P
