This makes the car more planted on the road, providing better handling and control at high speeds, especially in performance-oriented driving situations.

UV and Weather Resistant Finish: The carbon fiber is coated with a UV-resistant clear coat that protects the material from fading, yellowing, and sun damage. The finish also offers resistance to weather elements, keeping the diffuser looking sleek and glossy for years.
