I'm with the NJ BMWCCA at Thunderbolt yesterday and today.
Yes, even after modding the platic vent a bit, it still stuck out too far and I was getting rubbing at full left lock. I didn't want to leave it exposed just in case I ever kick up a rock or other object. So I went to home depot and bought a sheet of metal grating used for holding mud under tile. Cut a piece, spray painted it, and screwed that in place. No rubbing and it is rigid enough to offer at least some protection. Sorry, but I didn't take a pic of it. Its really nothing special.
