Exotica Carbon is now producing carbon fiber parts for the Gen 1 and Gen 2 Vipers. These door sills are 100% carbon fiber with 3D printed attachment points. These are not overlays on the factory parts but true carbon fiber pieces. They save 128 grams over the factory parts and install just like your factory sills using the same screws and caps to give the most factory look possible. The parts are 4 layers of aero grade carbon fiber in 2x2 twill weave carbon made in the USA! The parts also have a UV protected clear gel coat and three coats of automotive PPG 2021 high solids clear. They are then hand sanded and buffed. The 3D printed parts are epoxied on the back and come ready to install straight out of the box. Includes a right and left sill.
