The 370Z Weight Reduction Thread

wstar · 06-13-2011, 02:08 PM

Minor update on lug nuts. Top post lists the stock ones as "3 lbs". On my kitchen scale the sport package ones (are they all the same?) come in at 76.5g per lug nut, which is 1.530 kg for the whole car, or 3.366 lbs.

Muteki's open-ended tuner nuts come in at 25g (1.1 lbs total), and the closed-end ones at 60g (2.64 lbs) (per mfg specs).

It's not much, but every little bit helps

How much weight do you think you could gain by changing body parts to dry carbon fiber parts such as the hood, fenders, roof, etc...

RCZ · 06-13-2011, 04:27 PM

^ Not much.

It makes sense and I guess that's why Seibon does not advertise it's parts weight because they barely offer weight reduction over stock parts.

Yup. Good example: Varis semi-dry carbon hood, OEM replacement shape. 6 lbs lighter for $3.2k

6lbs is not worth 3.2k... unless of course you are rich, and building a real race car.

Would be cheaper to lose 6 lbs off your own body weight

the average cost of liposuction starts at 2k. Lol.

RCZ · 06-30-2011, 05:29 PM

^ running a few miles works too.

Equinox · 06-30-2011, 06:09 PM

^ well if you're blowing 3.5k on weight reduction already, I figured 2k for more lost weight is better. I suppose free is cheaper too.

Well it is 16lbs of rotating mass so yes acceleration will improve slightly.
Rotor, wheels can be big helps when cutting weight as they are also rotating mass.
