Squeaking/chirping sound after mods...

I see what you're saying. Guess I was mis-lead by the info on the site:

Slips on, over the car's wheel studs and indexing hub lip, keeping everything hub centric.

Sure, the spacer centers itself on the hub, but it's thick enough to make the wheel not center itself correctly.

If you want spacers, get some from Eibach, not some backyard engineer.

alright. thinking of going with a different brand anyways, so I'll look in to Eibach or Maximum Motorsports.

The noise hasn't come back since removing the spacer, just nervous to buy another pair and have the noise come back.

Go Eibach. I did a set on an Audi S4 and it rode great, no noticeable noise or ride change.

I disagree ... If you look at the pic on the link it looks like there is enough lip sticking out of the hub to properly align the wheel. Yes, it wouldn't bear as much of the load as the full lip of the hub would w/o them, but I don't think they are as bad as you think. I think the racing statement is more of a CYA thing...

Racecars run on small spacers like that all the time. Granted, they have stronger lug bolts...
However, I am just not a fan of spacers....

Took some pictures since their guy wanted to see if the part was warped before sending out another ( i had sent an email in over the weekend regarding the issue ). Anyways, here's how it looks. I guess I would assume the straight edge should lay flat with no gaps at all, but figure I should confirm before trying to atleast get it replaced so i'm not out money on wasted spacers.

I think the racing thing is a CYA also.

I spoke with the owner for Brembo50 a bit more and he is going to send me out a replacement. I asked him about the spacers being hubcentric and who makes them and he mentioned that the spacer IS hubcentric and he has a local company make them for him.

I have a private company do these locally for me. These spacers are hub centric because it fits over the original hub which allows centering with the original hub lip that sticks out

Tsb for rear brake rattle clips on page 9 of this tech section

My '10 track pack (same brakes as 2011+) did this and Ford wouldn't fix it. Glad they finally made a TSB to address the issue. Could be that and/or the spacers. Let us know what it turns out to be.

I'm not going to call BS immediately on the hubcentric issue, but something is fishy here. Look at these from Maximum Motorsports. They are NOT hubcentric. See how there is no hub? They look just like yours.

Now look at these from the same company. See the hub? I'm pretty sure it's there to fill that gap and prevent potential vibrations and/or situations like yours. The 20mm spacers I use have a hub on them and are hubcentric.

Also, were you supposed to run longer studs with these?

Just measured these and they appear to be 3/8 going off my cheapy stick ruler. I'm personally not trying to claim they are hubcentric, just only going off the info on the site and what I've been told by the company. I can try to measure how much of the hub is poking through the spacer to allow the wheel to center itself when I take the wheel off next time.

And no, they specifically said that longer studs are not required with these and they still allow for atleast 6 full threads.

They were rubbing on one side, but i've resolved that.

The noise is more or less a pulsating noise. The slower I go, the slower the noise and then it speeds up as I go faster. Double checked and the noise does increase slightly with brake pressure.

Thinking it has to do with somewhere in the rotating portion (wheels, rotors, etc) but no idea what it could be since i'm nearly positive nothing is rubbing. Possibly related to the spacers?

Open to ideas. I think tomorrow I might toss it up on some jackstands and let the wheels roll while I try to figure it out.

I had the exact same issue. I found out I had a bent axle. Ford originally said in had a glaze on my rotors. then my buddy Had the same issue and found out about his axles. I go to check mine and sure enough the same Thing

From the MM spacers without extended lip:
"Fits the unique front hub of 2005+ Mustangs."
"Not hub-centric; hub-centric spacers will not fit the 2005+ front hub."

sounds like 05+ front hubs are larger, and these are made to fit over the larger front hub but will never be hub centric bc the inner diameter is larger than the hub diameter.


Well, really this is right or wrong based on how you interpret what a "hubcentric spacer" is... does it mean that the wheel can fit centrically on the car hub over the spacer? or does it mean that the inner diameter of the spacer is matched to the car hub diameter... I suppose in reality it could mean either, so the term is somewhat ambiguous.....

In the case of the Brembo50 spacers (if they were flat) I would say both definitions are true. It appears that the spacer inner diameter is matched to the car hub diameter and it still allows some lip on the hub for the wheel to line up on the car hub as well. So I guess yes.

The more I think about it, you are probably right. After looking at some pics, my best guess is that the spacer doesn't need a hub on it if the existing hub is still doing it's job. You go with a bigger spacer, you will need the hub. So in that sense not having a hub on the spacer doesn't necessarily mean that it's not hubcentric.

But that's just a guess.

Yeah, that was the best conclusion I came to as well in regards to spacers with lips on them...

 

[jodadejss06gt]

My left rear is doing something very similar. I haven't had a chance to do any inspection of it. Def starting to get annoying though.

 

[riored4v]

well i got the new spacer put on over the weekend. fits much tighter like the driver side one and so far no squeaks.

 

[raptorman]

I had a chirping sound after puting axel back exhaust on and i used wd40 on the hangers and it went away,hope this helps ya...

 

[LTX]

I have that same sound coming from my front passenger.. riding stock though..

 

[weather man]

These are what I went with. Comes with new studs. Should be hub centric. No use report, since these are going on with all the other stuff. I went 7/8" in front to clear takeoff Brembo's and 1/2" in back. Using offset tire sizes. Mustangwheelspacers.com
