This is what I observed on my Mobile Service visit: The 7 or so spoilers that Mobile Service pre-fit on my trunk lid did not fit correctly. Visible air gaps were noticeable on every one, with some a lot worse than others. Some gaps were so big, two nickels could easily fall between the gaps.
This is what I was told by the Mobile Service Tech: Forcing an improperly fitting carbon fiber spoiler to conform to the trunk lid is only temporary and it will eventually lift....The other issue is, there is no documentation of batch numbers on the spoiler or the packaging. They can't tell if the spoilers they are getting are old or new production batches.
I'm back in the waiting queue for the next batch of spoilers to arrive. I did get my Dual Motor badge though..which I didn't have installed.
