The 370Z Weight Reduction Thread

Will fix, I didn't do the math myself.

So the front wheel weighs, 23.2lbs and the rears weighs 26.8lbs.

Perhaps the scales are off, but Nissan did advertise these wheels as 20% lighter. Not sure which wheels they were comparing to, but that doesn't look to hold true from this info.

Will add this great info to the thread as soon as I am able to edit the first post.

On the bridgestone website, the 275/35/19s are listed at 33lbs.

^^^ Thanks for doing that sensi09, rep for you for being proactive. I was just about to post that info up as well.

What this means boys and girls is that a set of CE28's in the same sizes will probably save us around 20 lbs total. In 18's we'll probably see a 25 lbs saving. (Just a rough estimate, so plz correct me)

And those are what I am getting!! I am just giddy about the upsprung weight being gone....

23.8 lbs for a 19x10 stock wheel isn't bad at all.

Compare to 350z Stock wheel weights
Wheel Version___Front Weight___Rear Weight
Standard 17"_________23.26 ___________24.14
Touring 18" v.1_______26.56___________26.56
Track 18" v.1_________18.19___________18.62
Touring 18" v.2_______24.8____________25.8
Track 18/19" v.2______21.25___________29.50

Wow, those wheels are really light considering they are stockers.

[Skaterbasist]

We are overlooking one area of weight saving for the 370Z: those Akebono brakes.

Since alot of G35 guys ended up upgrading their brakes to the Akebono brakes from the G37, which are exactly the same as the Z34 brakes, they all had a first hand experience at how heavy those rotors really are.

A 2-piece aftermarket rotor would definitely help. Especially since that's all unsprung weight, which has more of an impact on acceleration than other areas of weight.

[RCZ]

My rotors are gonna go almost immediately and in their place will go a set of DBA 5000, I will get the weight of the DBA's in a min.

There are just wayyy too many wheels to list them here, it will consume the thread. Thats the only reason I havent put them up.

[frost]

50, that's pretty decent. Thanks for the effort.

[OMGWTFBBQ]

That IS a pretty fancy looking spare. When I think of spares, I instantly imagine steel hubcaps haha.

[Crash]

That's a heavy spare, but a light sub woofer! I'll be leaving both in. I'm some-what surprised they didn't use the space-saver spare like they did in my 300zx.

Love how we can drop 50lbs in 1 minute.

Cool for the dragstrip, but it will mess with your handling balance on a road course. For anyone planning on setting their car up for the road course, just make sure you remember to take the spare and tools out of the back BEFORE you corner balance .
