Installation
Adhesive installation using pre-applied automotive tape, so no drilling or permanent modifications are required. Most installs take around 1–2 hours plus curing time, using basic hand tools; thorough cleaning and degreasing of the surface is required for optimal adhesion. Intermediate to advanced skill level; professional installation is highly recommended, since carbon fiber requires careful handling and precise alignment for the best fitment and finish.
Before You Install
Please inspect the spoiler and confirm the carbon weave, finish, and fitment before installation. This spoiler is backed by a 1-year warranty against manufacturing defects. If you have a fitment question, contact us with your year and model and we'll help confirm compatibility.
