-
UV-Resistant Coating: The diffuser is finished with a UV-resistant clear coat to protect the carbon fiber from harmful sun exposure, preventing fading, discoloration, and ensuring that the diffuser maintains its high-end, premium look for years.
-
Lightweight & Durable: The lightweight nature of prepreg carbon fiber reduces overall vehicle weight while offering enhanced durability. This ensures the product can withstand everyday driving conditions without compromising performance or aesthetics.
-
Protective Function: Besides enhancing the car’s look, the rear bumper diffuser also serves a practical function by protecting the rear bumper area from road debris, dirt, and other potential hazards that could cause damage.
