These things rock. Much stiffer then original, and didnt have to cut any tabs to fit them. Mechanic did say that they were a bitch to line up with the motor though. These things make the car feel more crisp and the throttle feels tighter.
I also had a ton of other work done to it such as upper and lower oil pan gaskets, cracked subfram was replaced with a used one that was also rewelded to reinforce it. and valve cover gasket was changed. These things could have attributed to the crisp feel but I doubt it. I think these mounts are the main reason for the crisp feel and tight throttle.

Do you know what model E21 they are from or what the part number is? Any more comments on installation?

Awesome, I'll opt for these when the time comes around.

The part number is 11 81 1 175 735, not sure what model they are from though. ordered them from bma and they were pretty damn cheap. Sorry, have no comments on the install since I didnt do it myself. I would've but had a shitload that needed to be done and didnt wanna lie under the care with nothing but a jack supporting the motor. Anyway, all my mechanic said about them was that they were a bitch to line up.

According to http://www.realoem.com that part number is for engine mounts for the E24 6 series and E28 5 series.

Maybe that explains why your mechanic had a difficult time installing them??

Thats the part number I used at bma and thats the part number that kowalski gave me on another thread. I'll try and locate the thread and link it later. Either way,he got'em on and they work.

How often should these be replaced? I have the engine out my car and am thinking I should add this to the list of things I should do and buy.

were they green? maybe they were m30 mounts.

I wonder how the e21 mounts compare to the m30 mounts

did you notice much added vibration?

nah they're black.

I have heard that the M42 mounts are filled with silicon or something to absorb vibration. Hence real pricey compared to a chunk of rubber.

bump, i need to know the answer to this

ak96ss · « **Reply #12 on:** May 03, 2006, 01:28:22 PM »

What I want to know is what it did with the engine - is it higher in relation to its previous position, lower, the same? I have that darned Sparco bar that I want to install, but I don't want to notch/grind my intake manifold to get it on.

i believe the proper E28 mount is 85-88. the mount must be green to fit properly...the thread needs to trimmed a little bit so that it can clear. i had a mechanic install mine and i forgot to mention that they needed to trimmed, so it was somewhat of a pain to install, still do-able though.

*EDIT*

they must be E28 535i mounts!!
