Review: BMW Group N engine mounts - AWESOME!

Hello:

Today I installed a set of official BMW Group N engine mounts on my 2003 330Ci.

To get right to the point, this is one fine mod! These official BMW Group N engine mounts are outstanding! The only bad part is that they are expensive; really expensive - $978 for the pair...

http://www.turnermotorsport.com/html...D=11812224413N

These mounts have all but eliminated drivetrain "wind up". Nealy all the rubbery-nish during throttle on/throttle off has been eliminated. As an aside, I replaced all three of my differential bushings about 2K miles ago but was disappointed that I still had wind up in the drivetrain during throttle on/throttle off situations. In the case of the original engine mounts and bushings (58K miles), none of them showed any sign of damage.

IMO, there are no downsides to these Group N engine mounts, aside from the price.

There is a slight increase NVH (Noise, Vibration, Harshness), most noticeable at idle. However, it is in no way annoying.

Interestingly, the increase in NVH during full throttle applications increases the growl of the engine. This is a good thing. It's not bothersome at all. In fact, it reminds me of the engine NVH on my good friend's 2007 Porsche Carrera. All late model Porsches have this trait, and IMO it adds to the liveliness of the car.

The Group N engine mounts have most certainly added to the liveliness of my 330Ci, and I am absolutely thrilled!

In my experience, replacing the engine mounts was a bit of a hassle, especially the driver's side because the steering column and U-joint is in the way.

Other E46Fanatics suggest they jacked up the engine and were able to simply replace the mounts. In my case, I could not do this without removing the aluminum engine mount brackets from the engine block (four 13mm bolts).

Anyway, if you've got the money, I'd buy the BMW Group N engine mounts over any other offerings. I just cannot imagine any of the stiffer, non-BMW mounts being better than these.

These mounts greatly exceeded my expectations!

Scott

You spent $1000 on motor mounts? Seriously? I know they're nice, but the $150 alternatives are basically as good.

This probably isn't a good time to tell you about the Bimmerworld Group N knockoffs for $199.99 then....

If you look at any of Scott's other posts, he goes for nothing but the best.

And with a car as mint as his, I wouldn't either!

Thanks for another great review and info Scott!!

not to mention the fact that bimmerwolrd sells the real group N mounts for only $400. I've got the $200 knockoffs on my e36 and have been quite pleased with them.

Actually, I got the Group N mounts from Bimmerworld several months ago for their "below cost" of $400. I should have given them credit for this, but when I checked their website this afternoon I couldn't find them listed. This is why I included the Turner link instead. If Bimmerworld is still selling them, sorry Bimmerworld.

As far far as the official BMW Group N mounts go, I strongly prefer the real thing instead of knockoffs. Who are these companies making these knockoffs? Do they really have the engineering and manufacturing expertise the Group N folks have? Can you really produce a knockoff for a fraction of the cost of the real thing without it being an inferior product?

As TCK said (Thanks!), my car is absolutely mint and I am very discriminating and selective with what I do to it.

As far as the cost of the mounts; well, I was able to retire at 52. And then, I liquidated 100% of my stocks in December 2007 when the Dow was 13,800. Let's just say the high cost of the mounts wasn't a problem.

To all you young folks busting your butts out there.....work hard and be your own advocate. And most importantly, save your money!

I hope all you are a fortunate as me. You must understand, you control your own destiny!

Good luck! Sincerely,

Scott

Thanks for a great writeup, SLO Town. I'd always read your posts with envy. Especially when you are installing new parts. Everything you have been adding to your car has been top notch. Please keep the show and tell the next time you have something new. There are those out there who appreciate this.

Thanks for the writeup - appreciated. Aside from the performance benefits of improved engine mounts, curious about how the engine handles the additional stress now that its absorbing those excess vibrations...

Nice to hear, I've been interested in the responses from people with stiffer engine mounts on street cars.

I can side with you for the increased NVH at higher RPMs not being bad if it is similar to a late model Porsche. Noticeable, but definitely nothing irritating.
