Black Carbon Fiber spoiler molding trim kits are made of a flexible Black Carbon Fiber molding that you trim to length and apply end caps to finish the installation. Black Carbon Fiber spoiler molding comes backed with 3M adhesive tape so installation is easy and simple. Spoiler kits are not meant to directly replace stock items on your vehicle, but serve as an easy aftermarket add on. Kit comes with one 4.5 feet long spoiler that needs to be trimmed at the ends. End caps are included to add a finished look.
