well i know for a fact that weight a lot less then factory parts.

the doors weigh 13lbs each.

as for the rest, unless i go weighing each part, the only ones i can be a little skeptical of is the front and rear bumper skins, being that the factory units are not that heavy to begin with.

but fenders, trunk, doors, hood, for sure..

cowl is prolly the same, dash is much lighter mine is 4lbs stock is MUCH MUCH more then that, center console is prolly close to a wash also.

again i dont think i lost 500 but im sure i lost closer to 250-300.

if i count taking out the HVAC, blower box, all the insulation, carpet, all interior, A/C, P/S, 5mph bumper supports, about 60lbs in extra wiring, ect. I am positive i lost over 500lbs.

however gained weight back in the 12pt roll cage, added chassis bracing, ect.

the stuff i had made by no means is junk, but they are not dry carbon either.
