MS3's possibly the worst Engine mounts

[BoostisLove]

They're terrible, every time i hit mid-high boost and then let off throttle, the whole engine jumps. I know that this has been stated before but maybe i broke one of my mount already? or is it really just this bad?

 

[Olestra]

I'm quite certain there are 3 years worth of threads on this subject. I could be wrong though.

 

[Stavesacre21]

Unlikely, considering how the new gen has only been out for about 4 months, tops.

Same engine, but so much is different that I find this to be a valid question.

As for the mounts, what are you noticing? The sounds? the feels? We're had hit or miss clunking/thunking threads that have been going around for something that's still unidentified.

If it is a mount, get it in the shop ASAP. The first gen did have a problem with motor mounts (if i'm not mistaken...could be the MS6 i'm thinkin of). Regardless, if you're in doubt, get it checked out to see if it's normal anyway.

If you are indeed talking about the thunking sound, welcome to the club. It's not all that great of a group to be in tho (homework)

Mounts between the two vehicles are identical.

If you want the best of both worlds between the softness and daily driveability of the rubber and the response of a urethane, our motor mount inserts are a simple installation and function beautifully.

Well, it's simple... the more free-play in engine mounts, the less vibration / shock will be felt in the car, thus a smoother, quieter, more "luxurious" ride. Or vise-versa. Take your pick.

I'd think that if you beef up the engine mounts to a significant degree, you will definitely feel it in the car... for better or for worse. I'd think that tighter mounts will add a little more "bite" to the feel of the car, might be nice in terms of performance vibe, but will increase vibration and general "jerkiness" (like when you throw a sloppy shift, etc).

I had two motorcycles once, very similar to each other, same engines, one had solid engine mounts, the other had rubber engine mounts. Each one had it's strengths and weaknesses. The one with the solid mounts did "feel" a bit quicker (even though it wasn't), because every move you'd make was that much "sharper" feeling, very "immediate"... but this bike DID exhibit extra vibration and jerkiness which was not welcomed for long trips.

The one with the rubber mounts clearly yielded more of a smoother, more "cushy" type ride / feel, very comfortable, but it was obvious that the engine was a bit "detached" from the bike when you'd be pushing it hard. The engine felt a tad bit more "removed" from the situation, less "bite". But, this bike was wonderful for long trips, I ran it 8600 miles in 2.5 weeks one time.

Again, a matter of personal preference. Have no comment on the MS3 yet as I still have not yet "beat" on it. I am not noticing any problems with it though, engine feels good. It may be a bit on the "soft" side, but for me, daily driving in traffic etc, this may be a good thing.

The issues with the 07's mounts was the bolt backing out and sheering off. the physical mount was OK. There were some mounts that failed but that was due to stupid modding. As for the amount of play in the mount DailyDriver hit the nail on the head. It's a compromise. More compliant mounts equal less NHV into the cockpit. This is what the aftermarkets for.

Problems with the transmission bolt continue to even 2008.5 model's. Lots had them back out. SO glad I got my TRZ installed.

I installed these inserts and I am very happy with their performance.
You can feel a small increase in the vibration of the car but nothing too significant. Great improvement.

Yes, the first gens had a very bad problem with motor mounts. I would actually reccomend the TRZ dogbone rear motor mount. Very stiff and drastically reduces the wheelhop, bad mount problem.

Polyurethane is stiff enough btw.

Sorry to drag up an old thread, but I'm assuming these are an automatic warranty killer? Then again I don't rely on the factory warranty all that much with new cars unless it's something blatantly wrong.

The MS3 2010 has some good engine-rock that's for sure. I'd like to get rid of that.

Not necesarrily. Dealer didn't care about mine when I went in for warranty work. Most dealers should be cool with it, along with other minor bolt ons like an SRI, TIP, BPV... just don't go in with a FMIC, TBE, and tune and expect free work to be done on your car.

Makes sense, most probably wouldn't notice the mounts anyways. After watching Jason's (corksport) video showing how much play there is in the mount, I'm going to order these things on payday and install right away. I'm so not enjoying the engine rock in my MS3.

It's a persistent MS3 problem, apparently easily solved with the TRZ rear and tranny mounts. Smart dealers should realize that you're doing Mazda a favor by replacing the mounts, but then - not all dealers are really that great.

Hell, when I was testing a few different cars this time, I got salespeople that literally knew NOTHING about the car they were trying to sell. The Kia salesperson knew NOTHING about the Soul, for instance.

 

[JS + MS3]

I'm getting the CP-E 75 RMM next week! :woot:

 

[JS + MS3]

and yeah, some members over at MSF.org pulled their stock mounts and they were bad.

Mounts between the two vehicles are identical.

The tranny mount is different. The transmission has a little 'tooth' that slips up into the new mount. The new mounts also have less rubber and some of what looks like cast metal around the bushing through which the bolt goes.

The rear mount is identical, and any aftermarket mount should fit the new model.

That's affirmative GhostRider. The Rear mount is the same fit in both gens. I've seen a solid mount installed on (2) 2010 MS3s

 

[spotch]

Are the mounts on the non-speed 3's the same as the weaker 1g mounts? I'm wondering how long my 3i's mounts will last.
