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.

Yeah the bride seats I got are just fine for me for DD. I made sure to get carbon kevlar seats that are still two piece and adjustable - opposed to 1 piece shells.

I forgot to let you sit in them wstar, I was hoping for an opinion

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.

I asked these guys to make a 370Z specific windshield but haven't heard back from them... maybe if they heard from a few more folks

SpeedGlass Racing Windshields - Percy's High Performance

May not be street legal, not DOT approved

[travisjb]

Scratch that....

these guys are hooking me up

Contact SHIELDS

They have three different thicknesses, and it is measured to fit the 370z exactly

It's not a bad price at all. What would be a recommended thickness? Or does it really matter. I would still drive on the road with it. I'm not DD but am a weekend warrior.

I'm thinking 3/8"s but going to ask around myself...

another reminder, these are not street legal

Nither is every other mod on my car. But I know what your pointing out though. It probably is a bad idea for me.

[travisjb]

it's your decision, i'm not trying to be preachy... really just for other people's fyi, so they know what they're getting in to if they do this... polycarb does not 'forgive' if your head crashes into it the way a windshield does - that's the key issue

[SPOHN]

I agree.

I received the following weight information from Seibon today...

Trunk: 16 lbs
Hood: 18 lbs
Fenders: 7 lbs each

... corresponding to these part #s

Trunk: TL0910NS370HB
Hood: HD0910NS370-VSII
Fender (each): FF0910NS370

... so now we need someone to weigh the stock parts... trunk will need to be weighed without the glass, if possible... or if not possible, I can weigh my rear glass separately

Not sure about the other stuff, but according to the OP, the OEM hood is 16lbs. It's already light because its aluminum I think.

All this CF **** is just for looks, no one makes them with weight in mind. Nobody ever posts the weights of their CF products(you have to specifically ask) because there is no weight savings.

I realize on the hood... I may end up just hacking up the OEM hood to get weight off and improve air flow

The fenders have the best shot of generating some weight savings... would be helpful for someone to weigh the OEM fenders
