Wtf is this big rubber spring loaded black rubber block on the driver side just under the intake box, in the wheel well?

Im trying to route my Boosted 6266 kit but the charge pipe hits this and sits way lower than I want it to.

Do we need this? Wtf is it and wtf does it do?

i tried to google 350z rubber block and got nothing. Shocker right?

And no I don't have a pic of it. Hopefully someone will know what I'm talking about with that vague discription.

If not I'll get a pic when I get home tonight.

You got an HR or DE? I just pulled my intake off this past weekend on my DE and did not notice what you're describing.

Right where your box is, under the sub frame. Look again you'll see it. You have to look from below or from the wheel well side.

its literally a rubber block behind the wheel liner.

I'm trying to figure out what u are talking about but maybe this will help.


Is it the block in the yellow circle?

Its just out of frame on in this picture.



But the little black plastic thing in the bottom center of the photo. Just below that is this huge spring loaded rubber block.

Ive done my share of taking apart and I cant think pf what you could be talking about... Maybe its a leftover piece of the car that smashed into yours...

Here is an under shot of mine

Is it the thing mounted on top of your brake caliper?

You trolling us or what? Why would you post a picture that doesn't show the thing you're talking about?

Otherwise, the only other thing I can think of being there would be a steering bump stop. Or some kind of sway bar bushing. Would be great if you could take a photo of it in the frame. Otherwise we are all just guessing here.

It's a chassis counterweight. The front one is exclusive to the ZR whereas all Zs have two additional counterweights towards the middle (near trans mount or incorporated into it) and rear of the chassis on the opposite side as the front one.

Do not recommend it's removal - but it won't hurt anything too badly - as it is there to "correct" the chassis harmonics so as to isolate the car from inherent road noise, bumps, grinds; and, due to a change to a more "natural" or "neutral" harmonic frequency, it also helps to reduce chassis flex and helps a bit to smoothen the ride.

Work your intake around it.

Not sure it if this was an intended design element or "a fix to a funk up after the chassis was built and tested"; but it was put there by Nissan Engineering so you can trust it (at least to a degree and moreso than home hacks who think they know better.)

EDIT: It should be noted that this is NOT exclusive to Nissan or 350Z or even just cars. All (or many) mfgrs use such "tuned mass dampers" in a wide variety of vehicles, machinery, etc. Nothing unusual about them.

Another one of Nissan's Z33 R&D outcomes.

How tf did you figure that out Mic?? Impressive

My alter ego persona's name was Claire B. Voyunt.

Nahhhh, I commented on this same one a couple years ago (I think in the threads noted above somewhere) after doing some research on "the big black box".

But I remember this as a young man.... my dad was a Naval Engineer and on one of the tours of a particular battle wagon he'd overhauled, he gave me a lesson on "harmonics" (owing to their use of same in ships and their subsystems), explaining it in as close to layman's terms as he could. Like anything else, none of it made sense until I was in college and took physics (or some such) where frequencies and harmonics came into discussion. Then, be like..... "Ohhhhhhhhhhh, nowwwwwwwwww I get it."

And Pops didn't think I was listening.

Now every time I see a tuning fork (not s'much anymore thanks to digital tuners), I think of Pops. Hahaha.

I'd like to leave it but I think it's interfering with my turbo kit and why the charge pipe is touching the steering rack


Might have to go. Don't think Sasha planned for that damper

If you are installing a turbo, it's not much of a concern
