This rear diffuser is AutoTecknic s newly released dry carbon fiber product for the G8X M3 M4. The diffuser is designed to mount directly onto the lower factory mounting location for a fast and straightforward installation. Manufactured using 100% genuine 3K Twill-Weave (2X2) Pre-Preg Carbon Fiber with our signature autoclave technology, this diffuser is finished with multiple coatings of high-gloss UV-resistant clear coat. Following the weight-saving principles of motorsport ideals, we utilize the autoclave vacuum forming process to produce this lip with superior strength and fitment.

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 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 vacuum (autoclave) to cure appropriately. 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 Performante Rear Diffuser comes with durable and precise mounting clips and is made with our autoclave technology for the ultimate lightweight, high durability, and exact fitment.
