Installation

Direct OEM-replacement installation using the factory mounting points. Most installs take a couple of hours including alignment, using standard tools. Intermediate to advanced skill level; professional installation is recommended, since carbon fiber requires careful handling and precise alignment for correct panel gaps and finish.

Before You Install

Please inspect the trunk and confirm the carbon weave, finish, and fitment before installation. If you have a fitment question, contact us with your year and model and we'll help confirm compatibility.
