Thanks have any experience or know anybody that does just curious of quality before purchase if you know what I meanI'm not sure about carbon fiber, however, www.vfnfiberglass.com makes a wide selection fiberglass parts for our cars. Front clips, rear clips, bumpers, hoods, deck lids, dashes and doors.
The doors are listed at 13lbs ea. They are out of Addison IL.
Here is that thread I believe: https://turbobuick.com/threads/weight-reduction-list.105295/page-2My search isn’t working, but there is an excellent thread on doors, weight savings.... it is very thorough and precise.
