Untitled Document RACING DYNAMICS carbon fiber engine covers are made by a autoclave and prepreg process rather than the normal wet process that many small shops utilize. True carbon fiber is made with a prepreg and then placed in autoclave oven which utilizes vacuum to form sheets of carbon fiber in a mold at temperatures around 350° F. Simultaneously the air is evacuated around the part and the pressure of atmosphere forms the part. This process allows carbon fiber to form into a strong and lightweight composite. Like most race car parts. On the other hand, wet carbon fiber is formed by using hand laid carbon fiber sheets into a mold then mixed with resin. This process generally allows air pockets to form in the carbon fiber material. This makes the wet carbon fiber structure weak and also is susceptible to changes in temperature.

You can usually notice the difference between wet carbon fiber and dry carbon fiber by looking at the surface of the material. Dry carbon fiber surfaces are smooth and don't show air bubbles. In contrast, wet carbon fiber is wavy and air bubbles are noticeable. Because of the molding process, dry carbon cost more to produce then wet carbon, however, since wet carbon fiber looses its durability over time, dry carbon is the best product for the long term.
Each dual cover BMW (E46 M3 & Cooper S which are 1 cover) sets come complete with billet aluminum mounting hardware and the RACING DYNAMICS logo in silver to compliment the black carbon fiber finish.
