Body accessories and styling components modify a vehicle’s exterior appearance and, in some cases, aerodynamic properties. These parts are installed on the body – including fascias, rocker panels, hoods, and roofs – and are typically constructed from materials like ABS plastic, polyurethane, carbon fiber, or aluminum. Installation often involves direct bolting, adhesive bonding, or utilizing existing factory mounting points. Many components integrate with or replace original equipment, requiring precise dimensional matching for proper fitment. Aerodynamic pieces, such as spoilers and diffusers, are designed based on airflow analysis to reduce drag or increase downforce. Protective accessories like mud flaps and side guards utilize durable materials to minimize damage from road debris.
