That's what I just installed, those and urethane trans mounts as well. Drove to work today and personally I think they're great, but I'm by no means a picky judge of NVH issues. There might be a bit more vibration at idle, but no big deal. BTW, my stock mounts were in good shape, I'll toss them up for sale if anyone's interested.

Can someone please tell me if these e28 mounts will fit a right hand drive uk E30 318is. My mounts need to be changed and i would like to run e28 ones like you guys but the part numbers listed in the above pages are U.S. Spec ones only and do not show up on my UK version of the BMW Parts Catalogue. Any ideas?

I've got some nice big yellow urethane mounts that are itching to get in there.  


Where did you get these from dude?

Gruppe:

Broke engine and donor engine side by side in the workshop. Hopefully  making one good one.

In the parts drawer, many parts replaced on the e30 M3 that really could  have been left in there  ;-)  

I've got a set of the 7 series hydraulic motor mounts (from my M3), which are quite  beefier than the M42 mounts (which I should replace, but are not cracked ...yet). This e30 M3 mount is about 1.27 mm taller. I want to put my  Sparco bar on top. Intake manifold clearance w/the original mounts was  not an issue. Before I try these mounts, anyone have any experience with  this particular setup? Any drivetrain alignment issues with that small a  height increase?

Also, I think the e30M3 flywheel (19lbs) is going to be a drop-in  replacement for the 28lb dual mass disc. We'll see when I strap the  starter back in there. The gears rings on both flywheels mesh perfectly.  I have a new 228mm clutch kit (oh well, can always buy another one, right?)

cheers!

Has anyone here had the (supposedly) infamous problem with the engine mounting ears cracking off of the subframe?  M20 guys have had this issue.  A stiffer mount probably is not something that would help ni that department.  After using these mounts on this car for 9 months I saw no cracks there, but who knows.


Yeah, i had this issue with the stock mounts. Which led me to change the mounts since the subframe was coming out anyway. After installing these mounts, the throttle actually felt more crisp (possibly due to the screwdriver syndrome). Anyway, i barely notice the extra vibration so i would definately say that this is a nice alternative to the stock m42 mounts.

just finished this mod.  i used the later green e28 mounts.  had to grind off the little tabs that are supposed to go into the slotted holes because the mounts sit reverse.  other than that it was a simple swap.  no spacers needed btw.  i do feel some vibration at idle like what has been described previously, but it definitely is not unbearable.  the mounts really stiffened up the front.  i can feel it on turns and acceleration and all out throttle feel is just superb.  i definitely recommend these when it comes time to do your motor mounts.

I just re-did them when I was doing my Z3 steering rack conversion.  If you snag a M10x1.5 die & die handle, you can add the threads you need onto the longer partially-threaded posts.  This saved me the hassle of dealing with 10 washers and whatnot.  Cut them down a little with a hack-saw and you are good to go!  When I get home, I will post up the pics of them.  My old ones were blows amazingly, but I guess it is to be expected after 3 years and being through a crash on my first car lol.

As for the mount tabs cracking off, I caught a number of cracks forming on the passenger side.  I MIG'ed that problem right up!  Pics to come!

Visit HERE for a plethora of 318iS stuff and some other randomness.  Would you say I have a, plethora, of pinatas?

Hi chaps, I'm just catching up on this as I have some pattern part E34 mounts and the steering shaft is knocking on the EM due to the engine moving too much and the Z3 rack conversion making things a little tight.

I just want to check, the mounts that you are suggesting are the US spec E28 528 engine mounts, 11811175735, taken from the first thread! The Euro spec part numbers are different so I want to get the correct part number before phoning my local BMW parts place as these will have to be ordered in so need to be correct...

Got prices on M42 mounts and E34 525i mounts as £58 and £33 each respectively, be interesting to see how the E28 ones match up.

Oh, and why don't people use M40 mounts? From what I've found they appear very similar to the E28 items...

The green ones are P/N 11811132793, sometimes they are not green, but they should be "heavy duty" mounts nonetheless.  The black ones are P/N 11811175735 and should be something less than heavy duty.

As for the ebay part, it does appear to be correct.

I just installed E24 motor mount ETK number 11 81 1 132 793.
They are huge compared to the M40 motor mounts and installing them was real pain in they ass.
When they were fitted I noticed that the engine leans a bit back more thus giving me more clearance to
the oil pan witch is nice.

But this also concerns me how will this effect my driveline. Does anyone have the measurements
of the stock engine mounts in height. the E24 mounts are 2.4 inch in height and when compressed they are 2.2 inch
Cane someone post the height of the stock mounts?
