It's a shame we can't get these in the UK. Gonna have to pay a lot more for the powerflex ones

No where. Bore them out with 12mm bit. Or reuse the sleeve that your shocks come with.

Can someone describe how these mount on the shocks? Which parts go where

You can order them from FCPEuro, price is similar. I got them there

I've checked that the top mount nuts were tight. I did not remove the shocks from the lower position during installation. I used the black Monroe washers instead of the silver OE "cups" if it matters.

Yep I notice this too on harder bumps. Perhaps this is why BMW made the stock ones super soft. The car feels fine but I do feel like these transfer more of a thump on harder bumps at speed. I have KW V2 coilovers and solid subframe bushings too which I guess contributes to this.

katsooba did you ever find out if they fit? getting a slightly used set of V3 and not sure if they come with their own proprietary rear shock mounts or reuse stock style - then it would be a good idea to go with these monroe. thanks in advance and sorry for waking the dead old threads
same question for the lower mount 907985 btw

btw Mpow3r_UK and other EU friends: check below links.. seems monroe is using some other part numbers here, for the individual parts of this kit? not sure if that would be all included in the 907984 kit.

So anyone else besides maddmatth and freedomfries experience this with a stiffer suspension or coilover setup? about to change to a V3 and wondering if I should go Monroe shock mounts in the rear or not? what subframe bushings are you two running to get the full picture? not sure if the V2 is adjustable but have you tried dialing it in compensating for the stiffer bushings (shock and subframe)?

[maddmatth]

I have AKG Motorsport SF bushings, the red 'race' ones.

Yes V2 has adjustable rebound damping, softening that more than the default setting makes the car too bouncy for my liking.
The 'thump' is pretty minor, not something I would consider a problem. Actually I don't notice it anymore, either I've gotten used to it or something has settled.

[bbnks2]

Could the thump be the rear struts banging off the bump stops due to soft rates?

[renizer]

Ok, received them to go in with my V3 this week

Update on the noise as I think I've figured out the cause. I believe the source of my noise were the loose bump stops bouncing around. Instead of using the Monroe washers, try using the stock "cups" that secure the bump stops in place.

I also painted the cups since they are known to fail from rust

[juld0zer]

It's a shame they don't include a basic leaflet showing the intended order of assembly. I've also got a knocking noise from both rears on corrugated roads. I omitted the supplied thick washer and just used the stock cup. I will try adding the thick washer on top of the cup to see if this eliminates the noise whilst retaining the bump stop holding characteristic of the stock cup.

The washer does feel about 1mm thicker than the cup. Perhaps i could also grind down the old spacer/collar 1mm?

Any update on this?

Did anyone get back to you?

Any DIY guides out there?

[simpleM3]

Wish I would have read this thread before impulsively buying the Monroe kit last night. Any proven or verified solution to preventing or eliminating the the noise?

thanks

What's the deal with these? I just ordered a set of Bilstein B8s and need new shock mounts.

They make it stiffer and less bouncy in the back I believe. I have B8s paired with these that I'll be installing in the following weeks

Isn't the monroe disk supposed to sit underneath the OEM cup (item D) on the image below? Some people decide not to use the monroe supplied disk and just use the OEM cup originally on the vehicle, but are people using both?

I am still battling this issue. Actually quite fed up with the noise as these are supposed to be an OE-like replacement part and in no way are they sold as a sporty replacement so I am surprised there are not more complaints about them but I suppose they are also a rather unknown product.

I want to keep the benefits but reduce the noise, so I will persevere. They are silent on big bumps and dips. It is only high frequency small bumps which cause a knocking noise from the rear. This is with Monroe OE Spectrum shocks. I expect different brands with their different damping characteristics will cause the noise under different conditions.

The noise can be reproduced by removing the top nut and bouncing the rear. Obviously futile for fixing the noise but just to demonstrate what I am experiencing. I seem to notice it only from the right side.

So far I have tried the following:
- Install supplied black washer in place of the stock cup
- Remove the shock dust boots completely
- Reseat bottom of shock in Lemforder bottom mounts
- Applied thick felt tape to tapered bottom section of the shock where it sits in the bottom mount
- Compared height of stock sleeve with Monroe sleeve. No difference. Inner diameters are also almost the same.
- Shorten the sleeves at the top to allow more compression of the rubber bushes. I chose to do this after separating the upper bush from the upper nut/washer assembly so I could see how far the sleeve was from the washer at rest. This caused more harsh knocking noise. Possibly because the stiff rubber bushes (versus standard foam) could not be compressed any further by the top nut
- Lengthen the sleeves using washers to minimise the gap between the top of the sleeve and the bottom of the top washer. This has so far produced the least noise but it is far from silent. Without the top washer/nut on, there is roughly a 1mm gap to the top edge of the top bush. I'm not happy with this solution as the top nut does not engage the nylock. All this testing has been done with the rear parcel shelf, trunk trims and rear seats completely removed. I am confident that with the rear fully assembled that the noise would still be audible as it is thumping against the body.

Does anyone with Powerflex or Dinan rear upper shock mounts have any feedback on this issue? The stock mounts don't seem to be compressed much either. Not as much as shown in another post IMO. At rest, it looks like no more than 2mm gap between the top of the sleeve and the top of the upper foam mount.

These bushings aren't producing whatever clunk you guys are hearing. You either installed them incorrectly or you didn't secure the top nut tightly enough (most likely). Installation is pretty straightforward...

It sounds like you aren't torquing the top nut correctly... I have at least two-three threads popping out the top of my nylon locking nuts. Torqued to spec. Car should be on the ground when tighten the top mount. Have someone use vice grips or something to ensure the strut isn't spinning when you try to torque the top nut down...

There is almost no way to install them incorrectly. I have torqued the top nuts down also when I originally installed them as if they were stock mounts (28Nm). There is adequate thread when they are installed like this but the noise is the worst. I have tried rocking the car before torquing, ballasting the boot with batteries and people to ensure the piston rod is fully up the sleeve before tightening.
I have only added washers above the sleeves as a test, which tells me there may be too much pressure on the bushes.

I really wonder if the Dinan version makes any noise. If it doesn't then I might cut down the lower half and make my own version of the upper washer.

rubber bushings don't make noise though
