Here's the AutoTecknic's newly released Dry Carbon Fiber Competition Sport Rear Diffuser for the F90 M5. It's designed to mount directly onto the lower factory mounting location for a straightforward and swift installation.
Dry carbon is the highest-quality version of carbon fiber products that are produced. Dry carbon fiber's name comes from its manufacturing process. Dry carbon fiber is formed 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 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 fewer pinholes and virtually no air pockets in the carbon.
This AutoTecknic Dry Carbon Competition Sport Rear Diffuser comes with durable
precise
one-piece dry carbon mounting locations. The diffuser is made with our signature autoclave technology for the ultimate lightweight
high durability
and precise fitment.
