I have the AKG ones. They are exactly like the second video. They are silent 99% of the time. The only time I ever hear them is occasionally at 62mph I'm right in the rev range where I hear a slight whine, but it goes away below and above that speed/RPM never to be heard again. Totally acceptable.

I love them and would buy them again if I ever had to.

Thanks amigo, that's what I want to hear. I'll be ordering as soon as I figure out 'from where'.

I ordered directly from AKG...

I'm all over the place on this one, but it's time to make a call on it as the diff is on it's way to MFactory.

What I DO NOT want my car to sound like:
E46 M3 3.91 diff and AKG bushings


Important note, those are SOLID diff bushings. Yes, I know. I'm listing this video as an example of what would be completely unacceptable.

What I think I would be ok with:
E46 M3 Revshift 95a poly differential and subframe bushings


95A diff bushings. Sounds fairly silent.
Important note 2: These are Revshift. They make M3 diff bushings but not non-M. Not super-helpful. How do these compare to AKG? That video sounds completely livable.

The evidence:
Polyurethane differential bushings - Fam thread 2014
Differential Bushing Refresh - Fam thread 2013
Akg rear diff bushing set - M3Forum thread 2012-2013

Lots of people complaining of diff noise on the internet, but a lot of it is apples and oranges, with other bushings being replaced also.


On one hand, I always replace OE bushings poly. I know what I am getting into in most cases, and have never regretted it.
On the other hand with if the OE are going to last 100k, I'm pretty fine with that if the 95As are going to be ridiculous.

If someone has the AKG diff bushings and can post a video, that would be great. Opinions are also welcome, but I know a few people (BP?) got them and hated them, but may or may not have gotten used to them by now.

Second question, where to buy? Who has the best price + quickest shipping to the east coast? Any vendors giving the hookup?

Subbed. Been wondering these same things for mine.

Subbed as well! If you do get the AKG, you should post a video of any cabin noise.

I'll try to take a video today of the whine I mentioned.

That would be great. Did you get a chance to do it?

No, my day got crazy. Aiming for later today (Sunday) since I just got home and it's past midnight.
