Anyone running AKG Aluminum Differential Mount Set or 75D Poly?

[M3only]

If so, why did you switch and was the result? Was it worth the upgrade over OEM?

Anyone running 75D? If so, I'd like to hear your experiences as well.

Thanks!

im listening too.

I used the AKG differential mount kit.
I then used OEM rubber subframe mounts and thought the increase in NVH would be be barely noticeable. I was wrong.
My car is now street only and I have regretted using the Al/poly mounts.
To me, the increased vibration is not worth the increased accuracy of the geometry.
AKG have disclaimers about using the Aluminum and harder durometer poly materials on a street only car, so it is not their problem.
I do use AKG poly on my track car and I'm fine with it in the correct application.

Is recommended 80A on street right?

but.. i must say the red bushings are very atractive even down the car...

I'm running AKG 95A black subframe mounts and AKG 75D diff mounts, no real increase in NVH in my opinion.

I also installed AKG black engine and tranny mounts, those definitely increased NVH.

Ill be buying 75D for all my rear bushings.

I have a buddy that DD's his S/C'd M3 with 75D and hes had no issues other than increased NVH.

I'm using the akg alum. mounts on the diff, and OEM rubber on the subframe. Best compromise between the two I thought, feels great. Was expecting to feel some nvh, but nothing changed, good ol M.

Thanks JayJaya29,

This is a route I've been thinking about going (purchased 95A FCAB), but of course, having the option to go one better crossed my mind when I read a number of positive reviews on the Turner Aluminum/Delrin set up. Surprisingly, there are not many reviews on the AKG aluminum diff mounts out there.

My car is not DD and I'm trying to set it up (short of gutting it) that will produce the best results for auto-x. Still deciding between the 75D RTAB vs OEM with limiters. So many decisions.....

FerM3,

Are you currently running AKG 80A RTABS too? Since you're always doing auto-x's, what's your opinion of them?

[jayjaya29]

I'm running the black 95A AKG RTABs, the fitment is perfect but I'm not entirely thrilled with their performance, there is credence that with the RTAB location its either spherical or OEM rubber, poly doesn't work.

Car rides great on em, its super planted, but have a lot of issues with lift-off oversteer.

[KnudsonsM3]

My car came with powerflex Rtabs. They've held up fine. Ill be getting 75D later.

Some goodies, hopefully I can get these on soon and try them out.

Very nice! Seems like a nice go between the aluminum differential set and the 95A set. Did you consider the 95A set?

Poly absolutely works as it does with thousands of other owners who use it there.

Yes I did consider the 95A until I got a DD.
