The 370Z Weight Reduction Thread

[Shamu]

I haven't removed anything and have my Nismo down to 3160 lbs with about 1/4 tank of gas and spare out. just upgraded a few parts.

Aluminum hat rotors, Berk HFC, WedsSport 18 wheels, braille battery, OSGiken LSD, JRZ coil overs

Maybe I missed it in the thread but how much does stock flywheel and clutch weigh?

Do the chassis dampers really work or are they dead weight for a track car? How much do those things weigh?

Is there nonfunctional weight that you can pull that won't greatly impact function of a daily driver? Looking for weight I can pull from front of the car mostly.

How much does stock Nismo steering wheel with airbag weigh?

Is the glass in the stock windshield the lightest you can use? Is there aftermarket glass that is lighter?

Really depends on your comfort limit for a DD. You've already done a lot of the easy things. Random recommendations that may or may not suit you:

*) Lightweight racing seats. Pretty expensive, but they reduce weight and also generally lower the center of gravity. Some of them are comfortable enough for DD use, although I'm not so sure about really long road trips.

*) If you don't care about audio, you could remove all of the audio stuff as discussed a few posts up.

*) Windshield washer reservoir can be removed to take a little weight out of the front passenger corner. TBH it doesn't weigh a whole lot though, you'd get nearly the same benefit just emptying it out and leaving it dry instead of lugging around a gallon of water up there.

*) There's a heavy metal weight on the underside of the rear lip of the trunk lid that can be removed. It's just there to balance with the struts to make the lid easier to open/close with minimal force. It's under the plastic and pretty easy to reach.

*) Switching to a set of straight braided brake lines (like CZP's) removes a bunch of factory mounting brackets/bolts/etc for the stock brake lines. I don't think I ever weighed it all, but it's a few lbs of unnecessary unsprung weight.

*) If you're not concerned about emissions testing, the FI Long Tube Headers cut some weight vs stock manifolds + cats.

The flywheel with dampner is about 30.9lbs from what I read elsewhere. On avg. a aftermarket flywheel is about 17lbs due to it doesn't use a dampner. Course you'll get more chatter. But who cares?

So far as glass I know a couple guys have used Lexon glass. It's defiantly lighter. You'll have to read up on it so far a durability and all. This way you can gets some tear aways.
