... well sir you were right! I had an assumption. I have no clue why it just randomly started doing it. Maybe the last couple times I mounted wheels it didn’t seat right causing me to just notice it. The first couple times after spacer install I may of just got lucky and they seated fine. But now with aluminum hub rings. No more vibrations. Only at high speed 75/80+ braking from slight rotor warpage.


To everyone else, thanks guys! I’m pretty mechanically inclined. But I like to have opinions from others! Love this forum with my old Z and my current Z. Always helpful! Wheels are re balanced. Hub rings got my wheels centered. Alignment is good. And only vibrations I have is from my rotors being warped. But the vibration is a lot less when I brake. So I’ll be replacing those in spring! Stay tuned for the install as well. It’ll be posted on here as well! :tup:

Glad to be of help.

The day I put spacers on at 81k miles mine started just as the OP describes. So I guess it can be either it made wheel bearing issue more pronounced or the spacers are unbalanced from the get go. If it's the latter I guess there isn't a solution.

What style of spacers are you running? I am on generic 25mm hubcentric bolt-ons and I have no ill effects.

Same as you but +20's off amazon that others have used. Even ground all the lattice off the brake rotor hub from the wheel so they're perfectly flat.

Stupid question - do you have any interference from the OEM wheel studs on the back of your wheels?

On my 2011 I had bolt on 20's and in the front the OEM wheel studs just barely touched the back of the sport rays and created about 1-2mm of interference keeping everything from fitting flush. This is partly why I am running 25mm all around.... (because lazy)

I got Z1 10mm up front with extended studs. And Z1 25mm in rear with stock size studs. No interferences with studs/wheels in rear. All I did was add aluminum hub rings on the hub centric spacers and my issues are resolved! :tup:

Good thought, I'll check thanks.

i have the same issue at 70-80mph any other speed it doesnt happen, its really annoying , i tried new tires, balance, alignment . =\

I had this issue since the day I bought my car a few months ago but for some reason didn't bother taking it back to the dealer. I assumed it was tires out of balance until I started reading threads on here including this one. Which caused me to overthink it. It did it from about 68mph-80+. Got an oil change today and on an impulse told them to balance my tires too. Turns out the rear two tires had thrown their weights and were out of balance. She's smooth as anything now. The tech at the stealership also reset my TPMS sensor which had been on since I bought it. Cost me about $160 total with Mobil 1 synthetic oil. Pretty high but worth it to me. So if you're having this issue start with a tire balance then go from there!

Having the same issues
 

Did you get that issue fixed?

I just did new rims brakes & rotors having the same issue

Yes hub centric rings in my aftermarket wheels and it resolved issue. No issues since. Minus my rotors being slightly warped and shaking a higher speed / heavy braking and will be replacing them soon.
