E12 drivers side motor mount?

[Grover]

It's time for me to replace my motor mounts and I'm looking for something a bit sturdier than stock. I've read that an E12 5 series mount can be used on the driver's side (this may even be what Ireland sells?) Does anybody have personal knowledge/experience with this? Yes, I know I can go with urethane, but would like to stick with rubber if I can find something a bit beefier than the stock ones. Thanks in advance.

E12 works E30 works But the best of the lot is ,,,,,,,,,the original BMW part.

Tim. Thanks for the reply, and I understand many folks desire to stick with stock parts. However, I'm curious how you define the "best" choice. My car puts out considerably more power than a stock motor (2.3L, ITB's, etc..) and I want some sturdier motor mounts that will help to reduce engine movement related to this increased power. Thanks again.

I think what Tim means is that the 'updated' 2002 part is virtually fail- proof-

it's designed with metal interlocks that can't come apart, unlike the hockey-

puck the thing shipped with.

Actually, I found it was stronger than the mount to the block-

after installing the updated 2002 part, I then broke the mount.

Some were made improperly, and have a propensity to fail.

Unless you want something quite stiff for performance reasons, the updated

one is plenty stout for all sorts of abuse.

Does anybody have any experience with a strut from the top of the engine to the inner fender or strut tower?

If so, how well does that work vibration-wise?

[TobyB]

I could never find a stout- enough location centered on the top of the head-

there are brackets that attach to the 6mm valve cover bolts,

but those didn't seem strong enough in single shear.

I know some people have used them...

Many of us with s14's run the stock mount......on track. A new stock mount will work well for your car.

You can stiffen up a stock mount by bending the tab down.

When I used to Solo 2 a lot (prepaired on slicks) I used the updated engine mount (rectangular one) and installed a hard rubber shim between the ears to dampen the mount under acceleration load even more. I just found a piece of hard rubber, cut it to size and used epoxy to hold it in place. This was over 30 years ago and it held up just fine, if I remember correctly it's still in the car. It did not increase the noise or vibration much but with the hard suspension mounts, stiff springs, Webers, header and non stock exhaust I'm not sure I could have noticed any difference.

Part of the problem is the rubber on the new OEM driver's side rectangular mounts is much softer than what it once was.

Why is it so hard (sorry - bad choice for a word) to have a stronger version of the stock 2002 engine mount that does not create more NVH but dampens the engine movement better than the original?

Certainly the rectangular (later) driver's side is better than the round (hockey puck) old type, but there has to be a better way. The AKG mounts that Marshall Lytle installed in his M2 were HUGE and HEAVY.

VW of Brasil (or Brazil) years ago came out with their own HD version of the stock engine mounts for air-cooled vehicles. They were simply a different durometer rubber than the VW of Germany parts.

A quick internet search brings up Darrell Vittone's (VW Inch Pincher driver) company offering water-cooled VW/Audi mounts:

Here is a newer HD engine mount set from CB Performance for air cooled VW's in CA.

Just saying - not necessarily complaining.

I believe your mounts are made from polyurethane - not rubber. Would like to see someone come up with a different durometer rubber mount that fits the M10 engine.
