This is AutoTecknic's newly developed dry carbon fiber competition brake air ducts for the F8X M3/M4. Similar to the brake air ducts found on the factory GT4 race car, it's designed to mount directly onto the front bumper on the F8X M3/M4.
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 material. 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.
Note: Modification is required to the bumper prior to installation.
