This is our newly released Dry Carbon Competition Rear Diffuser for the F80 M3 and F82 M4. Designed to mount directly into the lower rear factory bumper for a simple and fast installation. This carbon fiber diffuser is made with our 100% true pre-preg technology for the ultimate light-weight, high-durability, and precise-fitment. AutoTecknic Dry Carbon Fiber Diffuser is both highly visible and highly functional.

Dry carbon fiber's name comes from its manufacturing process. Dry carbon fiber is formed by using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold, and then into a sealed autoclave to properly cure. This particular method creates the least amount of waste and forms a lighter version of carbon than the "wet" method. The autoclave vacuuming process of making dry carbon means that there are fewer pinholes and virtually no air pockets that form in the carbon. Dry carbon is the highest-quality version of carbon fiber products that are produced.
