Weight Reduction Mods-240z

Recommended Posts

I'm with Racer Z, I'd like to see the weights of some aftermarket parts. Then we'd have a better idea just how much weight we would be saving by switching to them.


When I had my Z completely torn apart for the bodywork and paint, I took the opportunity to weight a few items on my nice digital scale. Here's what I came up with for some of the parts on my '72 Z.


37.10 lbs


4.40 lbs

Cowl with styrofoam pad intact

2.40 lbs

Center valence piece

1.10 lbs

Right and left valence pieces, each

13.0 lbs

Right and left fenders, each

23.30 lbs

Left door, bare. No glass, window frame, door latch, mechanisms, hinges, nothing except the bare shell

9.70 lbs

2.60 lbs

3.50 lbs

Rear hatch, bare. No glass, weatherstripping, rubber, latch, lock or emblems

2.50 lbs

Right and left headlight buckets, metal, each

3.00 lbs

Right headlight bucket, original FRP style. Yes, they are heavier than the metal ones.

Gas filler flap, metal

Maybe your guys' last few posts could be stickied as a new thread or something, coz thats great info. My small contribution:


From 78 280z:


~65 pounds (bathroom scale)

Entire RHS door




I was thinking the same thing. Don't know how to sticky it. I guess a moderator would need to do that.
