softest poly motor mount?

[BMWFanatic]

Whats the softest poly urethane MM for an e36?

I was thinking about the UUC or AKG black?

[Brent 930]

They're both 80A except UUC has more poly and is isolated. They feel just like fresh OE mounts.

[BMWFanatic]

how much nvh do you think the akg has over the uuc?

[jonmacs22]

Judging from how low your car is to the ground, I don't think that NVH from the motor mounts is what you are going to be experiencing.

Vorshlag motor mounts Chase.... LOVE MINE

Why soft urethane? Why not stock M3 engine mounts? Urethane mounts that are not through-bolt can tear.

Or the BimmerWorld solid rubber mounts (similar to the GroupN mounts)? I just installed a set of these a few weeks ago and have been very pleased with them.

I got these, installed last month, they will raise your motor about 3mm or more and the engine will still move almost the same, no NVH felt whatsoever, I wanna get stiffer mounts,

+1 poly melts and deforms with heat. It will eventually tear.

Stock mounts are the way to go for you. They last much longer and probably cost less.

I did notice the slight increase in motor height but I had a substantial reduction in motor movement and gained a noticeable (although not objectionable) amount of NVH. FWIW, I'm comparing to stock e46 non-M motor mounts on a motor making substantially more torque than stock.

Wait... what? Are you talking about bonded poly mounts, with the melting and tearing?



Our bolt-thru poly mounts don't melt, tear, fail, etc, well.... unless they are in a fire? Everything has a melting point, I guess.

They are not like the "soft" poly mounts, though (our E36 mounts use 95A poly for an E36 M/S-50/52). 95A poly is like giving "Enzyte" or "V1AGR4" to your motor mounts, permanently.

Just sayin'...

because i dont want to keep replacing them but i want something that will put the power to the ground but not have to replace every 3 years with little or no nvh.

will the uuc's eventually melt not like the vorshlag?

[ZimDoc]

Nothing is forever. All items you use alot needs to be maintained or repaired/replaced at one point.

I have a set of Vorshlag 95A motor mounts on there way and I'll be installing them soon!

Then UUC or Bimmerworld solid rubber mounts are the way to go. You still re use the heat shield so they shouldn't melt. UUC has a lifetime warranty for their mounts.

Vorshlag's will add some vibration vs. the ones I mentioned. You also re use the heat with them.

On my friends stock 330, the BW rubber mounts were so harsh he had to remove them. I have Vorshlags and they are pretty damn stiff, added a TON of NVH over my old crappy Irelands.

If you want something softish, I'd do stock M3 mounts. Or Vorshlags if you want stiff mounts.

Hmm... it seems the BW mounts are either too soft and have no added NVH, are much stiffer than stock with so little difference in NVH that my wife didn't even notice I had installed them, or they are so harsh they can't be tolerated. That's quite the range of experiences.

SiGmA, what transmission mounts was your friend running along with the BW motor mounts and how long did they leave the motor mounts installed? I noticed some added vibration at first that seemed to settle out after a few days. Did they also have a LW flywheel? Was the harmonic balancer ever inspected?

If NVH is a concern, stick with stock M3 mounts.

[dswads34]

I put the UUC's in my daily driver and didn't notice much (if any) increase in NVH over OEM m3 mounts . This was with poly trans, subframe, and diff mounts already installed, so my tolerance for NVH might be a bit different...

[Brent 930]

Corteco stock mounts are good, for say 60k miles. Only issue is they aren't solid. I rather have a solid mount of some sort and call it good for as long as I own my car without issues. Bad or worn mounts can cause serveral issues.

Hearing BW mounts are harsh is a first.

Ive had uuc black tme's for about 2 years now, do you have the race or black tme?

UUC red's (not the race version).

[Brent 930]

I have found that UUC bushings/mounts are more forgiving than most.

I believe he had the BW rubber tranny mounts, I think. He had the mounts on for a couple weeks at least. Stock flywheel, and the balancer appeared ok when we did the belts. No rubber coming apart.

Then perhaps he torqued his mounts down tighter than I did. It might also help that I've got my car set to idle around 900-950 rpm. My wife instantly noticed (...and complained) after I installed the Vorshlag poly mounts. She never even noticed the BW mounts.

[SiGmA]

His car idles at 650? I forget. Stock idle RPM. I wouldn't be surprised if he over torqued his nuts, he has done that before. lol. I thought I might have over torqued my Vorshlags due to the major NHV, but after loosening them, as well as talking to Terry regarding how much I torqued them, I still have NVH. Oh well in my car, I don't mind in the least. The car is "raw" lol.

Here are some pictures of what happens to UUC motor mounts. We took these off of a car today. As you can tell, the mounts both failed. There are less than 20 track days on this car, very minimal street driving.

BOTH sides failed on this particular car. When we got the subframe out, the driver's side top plate just fell off. The passenger side was plucked out using two fingers and minimal effort. The engine started moving, the pulley started pressing into the electric fan, which in turn pressed into the PWR 57mm radiator and killed it. This is the second time I've seen this exact scenario play out and the third set of these mounts I've seen fail with my own eyes.

Notice the pick of the top end plate... UUC not only doesn't use a through-bolt design, not even a J hook - it's just a bolt head plopped in urethane. These things have NO chance of lasting any appreciable amount of time.
