This is our newly released dry carbon fiber competition rear center diffuser for the F90 M5. Designed to mount directly onto the lower factory mounting location for a simple and fast installation.

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.

This JBSPEED Dry Carbon Competition Rear Diffuser comes with durable and precise plastic mounting locations and the diffuser is made with our autoclave technology for the ultimate light-weight, high-durability, and precise-fitment.
