The name "dry carbon fiber" is derived from its meticulous manufacturing process. This technique involves utilizing an impregnated piece of carbon material, known as "pre-preg," which is carefully placed into a mold and cured within a sealed autoclave. This method not only minimizes waste but also results in a lighter carbon version compared to the traditional "wet" method. Through the autoclave vacuuming process, our dry carbon boasts fewer imperfections, ensuring a flawless finish. When it comes to carbon fiber excellence, our dry carbon technology stands as the pinnacle of quality.
Elevate your BMW's aesthetics and performance with the superior AutoTecknic Dry Carbon Performante Rear Diffuser – a true embodiment of craftsmanship and innovation.
