[Doc]

Can anyone help me understand how the early 240Z could weigh approx. 2300 lbs and my 78 280 is around 2800?

I know the big crash bumpers didn't help but were is the rest of the weight and how can I remove it?

You loose about 200lbs with the removal of the bumpers and shockmounts. You can loose a little more if you remove the front valance and go with a motorsport update front and rear bumper. (Fiberglass)
Go with lighter alluminum wheels, loose the AC
The remainder is structural ie: larger frame rails, heavier rear end R200 instread of R190, larger fuel tank, raised rear deck to accomidate spair.
Also comfort issues ie: door pannel arm rest, carpet, springs in the bottom of your seat instead of webbing.
