or just unbolt it, take general x,y,z dimensions, and the rest is just a matter of knowing the density of the washer fluid and its a done deal.

Sorry guys, just went and looked and it seems like the washer fluid bottle will be a royal PITA to get to and the capacity isn't listed in the owner's manual. Maybe if I get REALLY bored one day I will pull it out, but I am not committing myself to that one.

haha, no worries, theres a slightly simpler way...empty it...see how much water goes into it till its full...done. You guys are silly. haha

^What he said.

I also checked the owner's manual, didn't find it.



Also, if you end up changing the brakes, can we get a weight on the rotors and calipers?

Yes. I will weigh the calipers/rotors when I do my brake fluid & pads before my baseline road course test coming up :).

Any significant weight to be saved by going to an aftermarket radiator? I know you track rats will save lbs anywhere thats feasible. Koyo or Misimoto et al make some sweet ultra light weight radiators for the 350z....Wonder what the stock radiator weights:pedobear: hint hint:tup:

Stock radiators are rediculous light, or at least they were for the 350Z. No I will not take the stock radiator out unless I have an aftermarket one to put in its place. :) I am working on that though so hopefully soon... :)

On the cover page, i noticed the weight of the stock sport tires are as follows:

Front Stock Bridgestone RE050A (245/40/19): 29lbs (13.15kg)
Rear Stock Bridgestone RE050A (275/35/19): 33lbs (14.97kg)

According to Tirerack (reliable?) they are

Front Stock Bridgestone RE050A (245/40/19): 30lbs
Rear Stock Bridgestone RE050A (275/35/19): 30lbs

Not a huge differnce, just currious which one is correct.

Also, found these tires on the same site, seem to be very nice and save weight to boot.

Front Pilot Sport PS2 (245/40/19): 26lbs
Rear Pilot Sport PS2 (275/35/19): 27lbs

Other's thoughts?

^^

Someone mentioned that...but on Bridgestone's site it says the weight I put up so I figured I'd go with the manufacturer.

Im going to take as much weight out of the front as possible to get closer to 50/50 :) Radiator, bumper, hood, battery. Might get a lighter battery and send it to the trunk.

Mike as soon as you have KW V3's available for it, hold me a set please.

Will do. :)

The flimsy looking stock rear camber arms got weighed today. Probably not going to get any lighter than that with aftermarket stuff, but here you go...

at least the after markets look much nicer..

And stronger! Not to mention they are adjustable. The SPL Rear Camber Arms came in at 5 lbs.

I had some SPCs on my G37.. now slam that baby ;]

please dont slam it...

Alrightt we got stickied!

well, replacing the seats with 13lb frp's, two piece rotors, wheels, aluminum race calipers, maybe the hatch with a CF one.
not to mention aluminum drive train mounts. lighter CF driveshaft and carbonetics CF clutch kit (350z one weighs 25 lbs for entire clutch and pressure plate assembly)

then just tack on headers, Titanium Test pipes, Titanium Catback, Dual intakes, Tune. which would lop off another 30lbs+

and you've have yourself quite a quick car. a little noisy but fast and fun.

if money was no option people could have a 2900-3100lb Z with 400bhp

If money was no option, I'd prolly be in a GTR :icon17:

Eh, money no object people could have a 2500lb Z with 1800RWHP.

I'm pretty sure the driveshaft in the Z is already carbon. As far as a carbonetics clutch, thats interesting and will be noted when something is released, but there's easier and cheaper places to take weight off on. The problem of course is how far the average person wants to go on their daily driver.

I'm waiting for Seibon to make a rear hatch, roof and hood in carbon....that will not only reduce weight, but also lower the center of gravity. The Sunline carbon roof is only a cover that will just add weight sadly.

can the roof of this car even be replaced? the hatch may save some weight.. but sadly the hood only saves MAYBE 3 pounds.. because it is already aluminum.. at least this is the case on the G37 and the 370z also has an aluminum hood.. but every pound counts in the long run..

I was fearing that, good call thanks for the info.. its the same story on the STI... Might end up getting a vented hood for various purposes..

True, but obviously your money accounts for something. a $600 dollar hood saving you 3lbs will not be as good of an investment as investing that money in a performance part.

the reason i say carbon fiber driveshaft is because an aftermarket version will weigh less then the OEM one ussually

Thanks for the info.If someone ever plans on uping their hp on their car, would they need a different set of batteries other than the pc680? Or will that batter work fine?How comfortable are those seats?Edited by AK.

tvfreakazoid - To answer both your questions...

The PC680 works fine for high horsepower applications. My time attack 350Z puts down 700+whp and runs off a PC680.

I assume you are talking about the BRIDE Zeta III seats? They are very comfortable once you are in them, but I daily drove my Evo IX with a set of Zeta IIIs for a long time and it was a pain in the *** getting in & out of the car, or getting your wallet or cell phone out of your pockets. Not recommended for a daily driver.

tvfreakazoid - It is unnecessary to quote the long picture messages, if you are going to quote something like that, please manually remove the pictures from the quoted message before you submit them. It adds clutter and since the browser has to display the pictures twice, it uses up valuable bandwidth from whoever put up the picture.

Also, you don't need to make separate messages to quote more than one comment. Hit the little quotations with the + sign next to the "quote" button for the ones you want to multi-quote. Then on the LAST comment you want to multi-quote, you press the actual "quote" button. What that will do is make a single message with all the quotes you wanted...

Its just a little annoying to have to scroll through2 comments and 9 big pictures to see your message "Thanks for the info" and "how comfortable are these seats"

You could have just made one message saying " Hey DDM thanks for the info, just one more thing..are the zeta III's comfortable?"

That is much easier to deal with, doesn't add clutter, nor does it eat bandwidth and its not annoying for the rest of us. That having been said, you should reserve different font sizes for when you are trying to emphasize the importance of something..its kinda annoying that all your comments are bigger than everyone else's font... That might just be me though.

I am not trying to be mean, he is just unfamiliar with the workings of a forum and I'm just giving pointers..its his choice whether he will take it personally or as constructive criticism...

i didnt feel as if you were trying to come off in a rude manner... but i was about to do the same thing as you.. i guess everyone has to learn.. hopefully he takes it the right way.

Stock Catalytic Converters = 21 lbs.

That is one fat cat... yay!

What went in its place????

Mmmmm ya did you replace it? id sure hope so since those things are not fun to take off.. thanks again for weighing all these parts!

Yeah, they were replaced with Berk Technology High Flow Cats (11 lbs. for the pair). Will be posting a group buy thread, dyno results, etc. within the next few days. :)

awesome! ^

I would love to get high flows, but i think it would make the car too loud...

They don't make a huge diffference in sound, but a noticeable one. I will post a dyno video sometime next week so you can hear it.

Wow.. Stock cats are really ugly.

Danke!

Can you make a non dyno vid man? The Dyno whine really drowns subtle changes in exhaust tone.... You should make a before and after video...

I'm not really interested in cats....when you have catless pipes let me know hehe. Unless the is no real drop in performance between the test pipes and the high flow cats...
