Ostensibly, there are these little black plugs that are available that are used to fill in the holes in the bumper if you take off your License Plate
. I read somewhere that they are black rubber or plastic, and work perfectly. However, I haven't been able to find them at this point. If someone knows, please let me know. I found some company that makes them for Porsches specifically, but not sure about fit, price and what you do about color, etc.
I took my own wing off last week, and I LOVE it, to me it looks way better without that fake piece of crap that has no aerodynamic value whatsoever (stock wing has no laminar shape nor does it have the proper angle of attack, both of which would be necessary to provide downforce as does a real spoiler).
I read a post from a guy a few months ago, who also took his wing off. He was the one who mentioned the little plugs for the holes, I believe. He also said that as far as the pegs were concerned, he left them alone. That way, should he change his mind, or want to sell the car, he can always put it back on. I kind of agree. I saw a wingless Celi on the freeway about a month ago, and had to catch up and get within about 20 ft before I could see the pegs. I figured if it was that hard for me to see, and I was looking for it, the average person won't even notice. Yeah, obviously it would look better totally clean, but as someone else mentioned, if you do that, you can't change your mind later.
