I have a guide on how to do the retrofit here:
And honestly any time I want I can just tape off and plastidip the rear bumper to break it up where the finned portion is and peal it off whenever. That's why I did it all blue!
I have gotten so many comments already! If you ever thought wow my car looks like an old lady car...
lower it, get it tinted and get the 3d Carbon kit and you will be amazed. It looks so good in person compared to the pictures. Finally a car show worthy car!!!
