spam bots...

eventually they are removed once reported just a bit of a lag time...

and especially now with AKs Family emergency...

thanks for reporting! :tup:

you could best get involved by actually owning a z...maybe...i dont know...call me silly...:bowrofl:

?

nm...it was a spammer asking how he/she/it could be best involved...

Does anyone know the weight of Stillen's headers and intake? Can anyone find out? IT would be really helpful if anyone could tell me..

Base/NISMO Seat with integrated SRS airbag = 42.4 lbs
Airbag assembly from SRS Seat = 1.6 lbs
NISMO Cat-back 'H' Pipe [Midpipe] = 17.2 lbs
NISMO Cat-back Rear Muffler Section [Can] = 35.2 lbs
NISMO Cat-back Front 'Y' Pipe [bolts to cats] = 13.6 lbs
Base/NISMO Headunit/Radio = 2.6 lbs
Rear Under bumper Charcoal Filter Cover/Shield = 0.4 lbs

Charcoal filter is kinda a wild card, but I had to take it off to make room for my passenger muffler can from GTM, Here's a picture

And here is the NISMO CAT-back that I weighed

Rear muffler section, Midpipe or H pipe, and Y pipe that bolts to the cats.

Just joined the forum and was happy to see this thread already here. Thanks for all the info so far. Just wondering, aren't the doors and hatch on the 370Z aluminum? I thought I remembered reading that somewhere but can't seem to find it again...

You are correct. Doors and hatch are aluminum..

i looked through the entire thread and didn't see a weight for the stock hood. i was getting rid of mine (crashed/bent but intact) so i weighed it at the recycler and made a good $5 :) weee!

The bare stock hood (no latch, weatherstrip, etc) weighs 16 pounds. not sure if you guys need proof. i can scan the slip and post a pic of the f'd up hood, if needed. just lmk.

jason, thx for going to the trouble... + rep

Anyone thinking about some Carbon Fibre parts?? I was thinking about a CF hood until I hound out the CF hoods weigh around 12 pounds and the Z's aluminum hood weighs 16 pounds. 4 pounds isn't that important for me to spend 500 dollars on it. I don't want to replace the hatch due to weight distribution. CF hoods for the 370z aren't out yet (I think)...Well yeah, any other carbon fibre products that could make a significant weight difference??

i like this thread

Anybody see the new rules for the T2 Z34 regarding SCCA? Ya'll better start putting the weight back on if you are going to run. Screwed. :eek:

it opened for me :confused:

Did you weigh the factory Nismo rims? or does anyone have the weight for front 9.5 & rear 10.5 Nismo rims? not the S-Tune, the ones on the factory car. :tup:

give me until next week when I powdercoat them and I'll let you know. I have heard it's 22 lbs. from Nissan, but not sure if that is front, or back, or what

Thanks, that would be great :tup: I'm considering picking up a set of these. I would think they the are lighter then the factory sport wheels, at least I'm hoping.

Cobra has a whole bunch of seats that are lighter at 8.2-9.5 kg. These seem to be much lighter than Recaro.

Hey guys, got some great info on aerodynamics. APR performance has their front wind splitters that give added traction and downforce. No idea about weight savings, but I do know that you can send APR info about you bumper and they will send you a custom wind splitter designed for your car. About $340 and $850 for a honeycomb splitter made from carbon fiber, fiberglass, and nomex honeycomb. The honeycomb splitter is stronger and is very light. The other cool aerodynamic part that has come out is the Evo-R rear diffuser. The diffuser should work with the front splitter and the underbody to create good airflow and suck the car to the ground for added downforce and stability at high speeds. The diffuser looks like it was designed for style, but it does have aerodynamic effects. $389 for the rear diffuser. I really like these offers and want to get them. I, however, do not want to buy a bigger wing pack to work with the diffuser and splitter. I want the added performance from the wing, but I really cannot have a bigger wing. The problem with that is that the standard wing is not designed to work with diffusers to maximize downforce and airflow. However, that is not a big issue. The other thing is that the Z does not have a really flat underbody to maximize airflow, but it looks sufficient. I like the packages for the diffuser and the splitter, but I'd like some input from you guys.

First off, an APR splitter wont save any weight since you aren't replacing anything, you are just adding it to the car. It is a great way to get some downforce on the front end though.

The EVO-R rear diffuser is for looks only. It does not offer any aerodynamic gains. It does not extend underneath the car at all. A rear diffuser that goes forward underneath the car (towards the rear axle line) will offer aerodynamic advantages, but the EVO-R piece is not actually a diffuser by definition.

Also this is not the right thread for this. None of the above mentioned modifications will reduce any weight on your car since they are all add-on parts, not replacment parts. Start a good aero debate thread in the track/autocross forum :).

evo-r rear diffuser is cosmetic IMO... personally, i haven't yet seen a rear diffuser that is highly functional in terms of adding downforce

the ARP front splitter is an option, but you can get a much more durable splitter with more downforce through Robispec

i'm going with the aeromotions r2 static wing from forged performance... great mix of looks, track and race proven aero benefits, and has been fited for our car by the guys at forged... it is also upgradeable to their active motion system if you chose to do that down the road

haha... looks like Mike and I are singing the same song... agree on the wrong thread comment as well

Yeah, sorry guys, just got curious about aerodynamics, but do you know about a good aerodynamic rear diffuser cause APR don't make one for the Z and other places just seem to sell cosmetic pieces. What is so stylish about getting a diffuser?

I think you're missing the point here, the EVO-R piece, although marketed as a diffuser, is not a diffuser. It is simply a cover for that lower section of the rear bumper. It does not extend underneath the car, therefore it is purely "stylish". Functional diffusers are excellent, but unfortunately nobody makes one for the 370Z yet.

Mike, give us a couple months..we're making a carbon one :)

^You mean you guys are making an real funtional rear diffuser? Will it be available to buy in the near future?

I like the sound of this. Who is "we"?

I do as well... consider me in...

rcz, would you be willing to start another thread where we can share design input? perhaps you don't want / need any, but this conversation doesn't belong on this particular thread, and you are likely to get the input anyways! :)

Great thread guys.

Even if you could reduce the weight by 500 lbs under the minimum weight its usually an advantage for you reduce that weight and put it back where you want, lowering your CG, etc.... not bad news at all....

most of you have PM :)

Guys, new problem related to weight

The Z's hood weighs only 16 pounds and Seibon claims that their DRY Carbon Fiber hoods weight about 12 pounds. That's a weight saving of 4 pounds. I don't think I'm that desperate for 4 pounds......Any ideas guys?? (i.e. correction on dry carbon fiber hood weight or lighter hoods) I and probably the rest of us are still trying to get that perfect weight distribution. So hard though...

^thats kinda old news, my suggestion to you is to leave it stock. 4lbs is not worth $600+.

yeah, you're right, but man what else can you do to save weight, besides rip everything out.......

Check the first page, there is plenty to do.
~After market performance upgrades are many times lighter
~Battery, remove plastic cr*p, etc.
~Interior parts can be removed or replaced.
~Carbon fiber

Yeah, that stuff has been done, but to balance the car to 50/50 with the Z's actual weight distribution at around 55/45 or 54/46, you would need to move around 160 pounds and around 155 pounds if you really lighten in to around 3100 pounds. I wish nissan could have made the Z's transmission rest in the back like the GTR's. That would have helped.

This is a question that I don't think everybody thinks about, but does anyone have any info on the weight of aftermarket limited slip differentials (i.e. The OS Giken LSD that I want that has 28 plates, Quaife, Carbonetic etc)....?? The Z's differential is mounted on its rear axle, so it would be great if it was the same weight so that it does not add weight or offset the weight distribution....

I have the stock diff sitting in my garage... I'm willing to weigh it, if someone can go to the aftermarket diff websites and check those... stock is heavy i recall
