Installation
Direct-replacement installation designed for the factory rear, with integrated LED wiring. Most installs take around 2–4 hours including wiring, using standard automotive tools; a vehicle lift is recommended for access and alignment. Advanced skill level; professional installation is strongly recommended, since carbon fiber requires careful handling and the LED wiring must be integrated correctly.
