Is there any aftermarket company who makes lighter doors for our cars?

 

i've heard of fiberglass door skins, dunno how much that would help

 

I've been trying to contact k1-styling about their EVO II Kit. It has lamborghini'd third gen doors, but I am inclined to believe that they are not using OEM doors. If they did give the doors a weight reduction.... it would be freakin amazing.
