Bmw e30 m52 rubber engine mounts

[Corasdad]

Can anybody confirm only e28 m5 mounts fit or are there other budget friendly options

[82eye]

guess it depends on the definition of budget. there's piles of aftermarket solutions. garagistic, condor, ecs, turner, etc

edit : if you only want rubber your options are limited.

I am sure I have seen a post saying e34 mounts fit, are polyurethane mounts worth the cost.

I've ran the RevShift swap kit (green). In my current car, and prior. They're the only ones I recommend.

Not seen good reports for these with them not fitting properly, same with the condor mounts but it's good to get real world feedback

think the original recipe was e36 mount arms with e28 rubber mounts. a quick google shows garagistic mentioning the 535i mount. there's info here on the board on it.

edit : poly is a matter of preference. there is more nvh transfer with poly. a lot will depend on the durometer you chose and other things.

That's what I have seen, think I will follow the tried and tested

The e28 m5 mounts (the cylindrical ones) are what I use on my car. If memory serves correct studs are a little long up top, but have worked great for over 40k miles. Have used poly/solid motor mounts before but too much NVH and eventually went back to rubber e28 mounts for street car use.

I've seen people say E46 M3 engine mounts upside down. Don't know anyone running this combo, but might give it a shot at some point.

castro does it that way. they are hydraulic and come with their own set of fail over time. they also place the engine a little different and require some hammering on the firewall / trans tunnel to clearance.

Well thanks for that, good to know before I bought them and found out the hard way lol.

Running some older generation Condor UHMW mounts atm.
I'm thinking about switching to something softer for NVH and because I have some small knock adaptations in low throttle spots in my timing table that could be real or false, but won't go away with timing changes, and at this point it's just easiest to just chase the idea of false knock.

I also have some current-gen Revshift mounts. They look really nice, but it looks like they shift the engine over a bit, and my existing downpipe won't clear if the engine shifts further to the right.
Supposedly they 3d scanned the bay/engine and these mounts put the engine where it matches the M20 placement.

AKG are (or I guess were?) back in stock, I'd consider buying them also because I'd rather spend the money than re-do my downpipe.

I have a set of new cylindrical rubber e28 mounts if you would like them.

I currently runt he 70a AKG poly mounts and am overall happy. They have a little nvh over the m20 with stock mounts, but are not bad overall. I had the revshift 80a mounts and they were a little noisy and could feel a good bit of vibrations at idle and low rpm.

One thing I did notice is the revshift mounts made the engine sit higher (maybe 1/4-3/8") and it was rotated a little more towards the booster. With the AKG mounts I do not have any issues with the booster (e90 booster), but the exhaust is basically on the subframe.

On my S50 swap I am running green Hamburg Tech mounts for 15 years now and they still hold fine, they did collapsed about 5mm over this time, I added spacer washer. Part number is 11811132793

I run E46 M3 mounts upside down and the NVH is fine. The nice thing about them is since they're slightly offset it allows you to move the motor around a little bit by twisting them. Takes some fiddling to get them sitting right but they're a good option.
