Diff bushing

[Eydreeyun]

I'm having trouble picking up a brand between AKG, Revshift and OEm z3m diff bushing. Both Z3m and AKG's street bushing is 10$ expensive than Revshifts and I looked for reviews on Revshifts and none of them are differential bushing reviews. Also why I'm considering Z3m is because I'm getting the m3 offset bushings and have a shop press it, should I just have them press the diff bushing all in one? I hate noises in the car, car is daily driven.

if you have the time to hold off for 3-5 weeks, look up user "Lencas" on here. he makes bushings in polyurethane & Ertalon. The polyurethane comes in 75d and 90d, I believe. 75d will be more stiff than oem but noise level shouldn't be very noticeable, if at all. He makes quality stuff and beats pretty much every vendor out. Downside is he's across the pond so it may take a little while to reach you. I will say that I'm certainly happy I waited. If youre really worried about noise and don't have much time to wait, then just go oem. Have the bushing pressed in by the shop. It is pretty easy to break the diff cover if you don't do it properly.

Yeah, I can wait. I'm still waiting for the coilovers to come. So what kind of bushings did you get? how are they holding up? I know its a wear part, but I need reliability to last for year or two.

I just put in a Diff with an AKG poly bushing.

I cant say I notice any difference.

a year or two? it'll last a hell of a lot longer than that. I went Ertalon, which is extremely stiff. Noise does not bother me. My diff bushing is actually a delrin one from VAC. Only reason I bought it from them is bc I bought finned m3 diff cover from them as well and had it pressed in... Plus Lencas wasn't around yet. What I did buy from him are:

Ertalon control arm bushings
Ertalon rear subframe bushings
90d rear trailing arm bushings

all were produced very well.

Although I've never used it, Lencas looks like a good product. I went with the Powerfelx diff bushing. and it slipped in by hand

[Eydreeyun]

Yeah, I went ahead and ordered the bushing from him. About the longevity, I was looking at a site called bmw.e30tuner.com, He state that the bushing he used wore after a year or two and it gave slop in the rear.

Edit: I'm looking at his control arm bushings, does Lencas squeak like AKG's?

There are no reviews of the Revshift bushings yet because we just released them a few weeks ago.
Ours is $50 with free shipping. So, you probably still paid more by going with the lencas stuff. Also, we mold the bushings ourselves which allows us to control the curing process to ensure a high quality part. The polyurethane we use was formulated by a world class laboratory specifically for automotive applications. Lencas buys chunks of urethane off the internet and cuts them down on a lathe. There is no proper quality control or engineering there.

[Brandon12V]

They don't squeak at all. but I didn't buy urethane cabs. I bought Ertalon.

Get the solid rubber Z3 one.

[Eydreeyun]

Yea I thought about that, but an easy slip on bushing is what got me. Limited time gets in the way =/

Yes, it is true. That is why his thread is titled "e30/e36 machined bushings".
