The sites really don't say anything about weight, but I'll keep looking for it...

very interested in weight reduction, here are my opinions:
-CF Front fenders, are the seibon lighter than stock?
-CF racing mirrors, they dont make them for the Z?

-How much weight will you increase in the front with a supercharger? :S
the intercooler, piping, water pump, etc...

*might* have power-to-weight ratio on your side.. :D

Im sure it will :tup::yum: :driving:

but any approximation of the weight added? caz it will be abit harder to balance it with the rear..

- CF front fenders: The stock fenders probably weigh 3-4 lbs. each so not much room for any major improvements there. The SEIBON dry carbon might save a lb. or two, but I can almost guarantee that their regular carbon ones are at best, the same weight. They are 10mm wider though, which is awesome.

- CF racing mirrors: Haven't seen any 370Z specific ones yet, but as reference swapping the OEM 350Z mirrors to tiny, non-motorized Craftsquare mirrors saved 1 lb. each side.

- Supercharger system: Expect anywhere from 60-100 lbs. probably in added parts/fluids.

Why would you want to balance the car at 50/50 when the car's designer put a small forward bias that was designed to give the car perfect 50/50 when exiting a corner under WOT?

Haha Josh that Gen3 for free sale came too late for me, I would have jumped all over that but went with the Berk group buy, oh well. C'est la vie.

so if the supercharger weighs 100 lbs, and about 9 lbs is equal to 1 hp, you only need 11.1 hp more to offset the weight increase?

For accelleration, yes. There's no doubt your car will accelerate faster with an SC. Cornering and braking will always be affected negatively by weight though.

Need some clarification from the first page, are stock cats 21lbs each or total?

Total

There is a product that could be considered for weight reduction...It has not been specifically made for the 370z, but Stillen made one for the 350z. It's an aluminum radiator...These radiators are lighter and more efficient than the OEM. It's currently on the Stillen site, so check it out and tell me what u guys think...

I was wondering why no one here talks about radiators too much. It was a nice mod in the Subaru community.

I don't think they are lighter than OEM. The OEM 350Z radiator is super thin with plastic end tanks. Incredibly light. Crap, but incredibly light crap. There's also the added amount of coolant which weighs a lb. or two probably.

Actually, if you're going to remove the a/c (race car or extreme TT car), an aftermarket radiator makes sense... OEM, the radiator and a/c condensor are basically fused together... ie no way to remove the condensor even if you pull the rest of the a/c system... so it is dead weight

I was thinking if you remove the a/c and stick in a radiator that is half the length but thicker you could stick a single turbo up front.:yum:

Thanks Mike and the rest of you guys,

I thought it would lighten it up a bit cause' that's the main reason I thought of buying it. Better cooling, less weight, better quality and I thought it would be the best, but I since it does not save weight, I'll stick with my oil cooler...

I was wondering if anybody had any more ideas to reduce unsprung weight in the wheel area. I've got my 18" volk ce28n, rays engineering wheel nuts (save about 750g altogether....yeah big savings), and will be getting my AP Racing big brake kit. The wheels and brake kit help the most, but is there anything else that I could do.

diet

Nitrogen in the tires? ;)

lol, yeah, I'm not sure how much weight I can lose without surgery...I only weight 140lbs, I'm pretty lightweight

There is not much more you can do in that area, maybe a coilover setup might be lighter but not 100% sure.

RCZ, some updates to your list if you want:
I am looking for aftermarket suspension and other parts but no one lists the weights on their website, will contact a few vendors and ask for weights.

~Berk exhaust:
-Muffler: 32.2lbs
-X-pipe: 12.2lbs
-Resonators: 8.8lbs each (17.6lbs total)
-Bolts & Gaskets: 1.2lbs
Total: 63.2lbs

~Fast Intentions exhaust:
-Whole exhaust with SS mufflers: 47lbs
-Whole exhaust with Carbon fiber mufflers: 41lbs

~Fast Intentions Long Tube headers:
-Whole piece: 21lbs (Per thread a recorded weight loss of 17lbs total)

nice addition

Here's another

Custom aluminum single side cat-back with Burns Stainless racing muffler and clamps... 15lbs

Whoa...nice

Great

so the Berk exhaust is about 20lbs heavier than FI?

Yes, of the exhaust reported FI is the lightest aftermarket, though I am sure some others are a bit lighter which have not been reported.

anyone have any info on stock brakes sport and non sport? sport and non sport rotor weights as well?

stock sport FRONT rotors supposedly weigh 30lbs a peice on the 370z, according to racing brakes
Two-piece rotor (Open Slot) - 370Z (Sport) FRONT 2009

Which is more than my 19" rims.

Damn, 30 lbs. Definitely have to look into getting a two-piece rotor.

I assume the drilled weighs less than 19 lbs slotted rotors?

negligibly less.

Figured it would be. Was assuming a little under a pound less per rotor.

Some stuff that I weighed, used a bathroom scale, may be off by a pound or so.
bc br coilovers 54 lbs / stock 55 lbs
HR springs 31 lbs / stock 17 lbs
ichiba 20mm ver 2 spacers almost 2 lbs

How much does the KW V3 suspension weigh?

KW V3 coilovers are too cool to be weighed, chuck Norris will drop kick your bathroom scale.

^Awesome line lol, I ask cus I'm planning on buying them & was wondering what the weight difference was vs. the stock suspension?

i had 2nd, 4th and the reverse gears removed.... reduced weight by about 8-10 lbs. I regret removing the reverse a bit, but im getting used to putting it in neutral, opening the door and pushing with my foot, so its not so bad
