I always thought the plain Carreras needed some type of lip, but I didn't want anything too big. I looked at many, but went with the GT3 design. Joel was very helpful on the phone and it shipped out and was received quickly. I was thinking I might have left it black, but my car is Basalt Black, and it relay doesn't match very well. I test fitted it on the car before I get it painted and took some picks. It feels and looks very sturdy, and fit so well that during the photos it is holding on by friction alone. Hopefully I can get it painted this week, and get it permanently mounted by next weekend. I wil post the photos when completed.
