e28 'Green' Mounts - BITE ME!!

[etxxz]

I broke them both in about 6 months and roughly 5000-6000miles... then again, those include a lotta track miles. maybe 4000 of those were street miles.

In any event, you can barely see from the picture, they are ripped almost all the way through on the sides. The fact that i can separate them by hand tell u something.



So, IE was nice enough to sell me some e28 'yellow' mounts :nice:
[notice what the letter says]


sometime later in my bat cave




Took em around the block and i could actually daily drive them. They are not as stiff as i thought...yeah its dirty down there, you don't wanna see me now..

when your neighbor's beard sets on fire, put yours in water..

Have you got any vibration from these?

How much did you pay for the mounts?

You should check out my solid aluminum mounts. Smooth as butter. No lie :)

I made my own solid aluminum mounts after swapping out my IE urethane ones.

Give it up Luis!

I may end up leaving the e28 Greenies in the Parts bin at work ;)

Congrats on graduating!

^^^ jaja all day!!

not as much as i thought really. i'm so used to my stiff suspension (450/550) this really didn't change much ex i like how solid my driveline got all of a sudden.

~$168shipped for all 4 though..

naaaah i just drove an e36m3 with solind mounts and it was pretty intense... maybe i'll get to check em out this weekend :mrgreen:

i could see how you could make them.. but some advice would be very appreciated man!!

[etxxz]

houston.. we have a problem!!

well, i take it back, i could not daily drive them... just yet. something is wrong. after 2000rpm the whole car will start vibrating... maybe not as exagerated as i describe, but its not normal, even with the stiffer mounts.

I got under the car while someone accelerated (in neutral), engine mounts are cool, no vibration. I put my hand on the (hot) engine, i feel minimal vibration = normal. I touch the tranny under revs and OMG its shaking right to left pretty badly.

Someone please tell me what is wrong. I read somewhere about preloading the transmission mounts. I can't seem to not pre-load them unless i torque them too lightly.

suggestions GREATLY appreciated as i gotta drive about 600miles round trip this weekend to and back from a track event. Thanks

I installed my IE transmission mounts without any preloading procedure, and it didnt cause any issues. Good luck!

[nando]

it will be interesting to see how those hold up. I've heard some not-so-great things about IE poly mounts, but who knows. hope you get that vibration issue sorted!

[e30s52]

I had the same problem with my ie mounts on the tranny. I just ended up getting the stock ones because I didnt feel safe with them not torqued down. The shaking gets really bad around 4500 ish right?

[etxxz]

actually, it gets smooth above 4500rpm, but between 1700 and 4000 there's even in-cabin resonance..

how do i fix this??! gee i still have the stock e36M mounts, i'll put them back in if anything

[e30s52]

Try the e36 mounts. Thats what I did and it fixed it.

[etxxz]

yeah, that's what i'm using. I'm gonna really torque them this next time. they better work. I'd hate to have to put the original ones in. they are still in good condition.

I had the same problem with my passenger mount after one track season. I will replace it this winter, but my solution is different than yours.

I am going to buy the AKG poly mounts that are made for the m5x/s5x swap. The advantage is that they are actually engineered to accomodate the angle of the e30 subframe and the e36 engine mounting arm, which obviously eliminates the twisting force applied to the e28 mounts when tightened down. I've seen a set of these on a swapped car and spoken with AKG and these mounts are the best option on the market in my opinion.

For a street car the e28 mounts are fine, just check them regularly for tearing. For a track car, the e28 mounts do not last. Although the akg mounts are $200, that's a lot cheaper than tearing an e28 mount on the track and putting your motor through your radiator. Just thinking about that scares me.
