I have been looking at getting a spoiler for my 2006 NC and was undecided between the carbonfiber vs fiberglass you are offering. I noticed that you are switching to urethane instead of fiberglass. Which would you recommend and why? And do you know when the urethane will be available? Currently i am leaning towards carbonfiber since it is available now and i dont plan on painting the spoiler i end up gettihg, but i can wait for the urethane based on your recommendation.
