    • Karbonius Composites delivers carbon fiber E46 3-Series doors that weigh 11 pounds each

      It is not always about adding power but also shaving weight where you can if going for an all out race car build. This definitely is a product for race builds as there is a safety tradeoff with these carbon fiber E46 coupe doors.


      They only weigh 11 pounds each and look beautiful too:










      If you are thinking the E46 M3 CSL had carbon fiber doors that is incorrect as it had carbon fiber door inserts. These will shave quite a bit of weight even on an E46 M3 CSL.

      Contact Karbonius Composites in Spain if interested.

      So how about an E92 version next?

        Factory e46 doors weigh about 93 lbs each so its a savings of about 164 lbs minus the windows and locking mechanisms etc. Definitely significant.
