Breedt RMM Opinion after install and removal

[boyracer]

hmm. I took the stock one, hacksawed out the big end bushing and replaced that one only. so the factory small end is still intack and the hollowed out big end is history. best of both worlds, and cost was like 50 buckish. just saying, bob

What exactly did you replace the big end bushing with? Sounds like you may have replaced the hollowed out bushing with a solid one. What material was it made from?

Thanks

Maybe look into the mountune/Cobb mount ? Are you going to sell this ?

 

[DP03]

Cobb here. Just like stock. No break in period. Looks like the Cobb wins the consensus so far on this thread.

I seriously could not feel any vibration increase over stock.

 

[boyracer]

bobmax, with a yellow colored bushing. I believe the purple ones are harder yet. powerflex sells them. bob

I'm gonna pick up a Cobb mount this weekend. I don't mind a little extra vibration at all as I can tap dance the motor off the fire wall pretty easy in my 2016 . My 2005 srt4 was making 300 hp and 332tq at the wheels with solid boomba mounts. That baby shook like a sob but it didn't bother me much.

Interesting. I have the Mountune RMM but have been reluctant to install it, partly because it makes me nervous but mainly because I haven't yet experienced the notorious firewall slam. Enjoy some spirited driving but I try not to slam this puppy into gear if I can help it. I'm sure that once/if I experience it, I'll probably change it out immediately.

There is no possible way for the engine to hit the firewall with all three motor mounts installed.

Now that I have driven about 600 miles on it and then taken it off. If you are into making your car the most uncomfortable car you have ever driven, you should install the RMM. Anyone on this forum who tries to tell you otherwise is full of themselves.

This thing, locks down the motor and it transfers every vibration back through the car. Everything in the car was shaking and everything was vibrating. It was like having a large cam installed in the car. As a daily

While I respect your opinion and experience with Fiesta ownership, I have to disregard some of your review. Firstly, 600 miles isn't nearly enough time or mileage to give a fair evaluation of a rear motor mount. Most mounts require at least 1000 miles of break-in, or even more in some cases before they will calm down. Secondly, I experience NONE of the vibration like you are experiencing. Everything was shaking? When? At idle or past that?

The difference between with and without, with, traction is a little better. but, maybe not, with the RMM on the car, I laid down a strip of tire marks over 30 feet for the first time since I bought the car. Without the RMM, I am unable to lay down that 30 foot skid mark. That seems to tell me, better traction without it.

I believe this is a sign that the rear motor mount is doing it's job. You can deliver more power because you aren't experiencing any power being lost by movement of the engine.

I want to give my input on this subject, as I have a Breedt rear motor mount as well.

I feel the Breedt RMM has been given a bad rap here. As mentioned, not many people have this mount and I feel that has to do with two things. The first, is that Breedt does almost no advertising. They have a forum prescence but only on select forums and rarely post, mostly showed up after releasing their mount and then disappeared. Breedt is also not a performance company, but a machining and tool design company who happens to make a few automotive products.

Secondly, I feel that Cobb is such a big name performance company that naturally, more people will purchase just from that alone. And they do a lot of advertising as well and participate in the community.

Now that that is out of the way, I also don't feel that any particular mount is "bad." Every mount has a stiffness or durometer rating. With higher durometer is more harshness and most companies with the higher ratings don't necessarily claim their mounts will be good for daily driving. Some mounts get a bad rap because some people may not do the research prior to purchase and just grab a known name brand or a mount their "buddy" bought.

Concerning the Cobb, they claim a stiffness rating of 68A for the large bushing and 85A for the smaller bushing. I couldn't find the Mountune RMM stiffness rating on the product page. I was particularly interested in the Breedt mount however because it comes with a 40A large bushing, which based on my research, is the softest rated bushing for a Fiesta RMM on the market. CP-E is stiffer than Cobb as well as the Boomba I believe.

I like the idea with the Breedt that you can switch to a 60A bushing (which is included) if you want a "stiffer" experience or decide you will be racing more. It also is better in the long term because like anything, bushings eventually will fail, so on the Breedt you can take it apart and replace the mount when it gets warn. You can maintain it, while you would have to replace other mounts entirely. I opted to stick with the softer pre-installed 40A bushing as I wanted as mild of NVH as possible. While it has the softest bushing rating, keep in mind there is no smaller bushing, the mount is solid billet besides the large bushing. I feel this may slightly negate the lower durometer bushing, however the smaller bushing side is typically the side with the most movement on the stock mount, so this makes sense as to why the manufacturers above put a higher stiffness bushing on that end of their mount.

My impressions have been good so far. Install was easy, fitment was perfect and the quality is great. At first, I was put off by the noise but almost within the hour it tamed down. Even a week after, I noticed a difference at how it calmed down. At idle, it feels like stock, even with AC on. There is a "sweet spot" where the vibration is worst and that is between 1000 to 1200 RPM where the dash vibrates. I'm not sure where your "excessive vibration" issues you mentioned are coming from. The main difference that I've experienced is engine noise. I feel that this is because of the increased resonance, the mount doesn't absorb sound like the stock mount would. So overall the engine is louder, but in a good way. It sounds more aggressive, almost like there was an exhaust added but the noise is from the front. I personally like the increased engine noise. It's not loud by any means, just more audible. As far as feel when driving, like most mounts, it does a great job at delivering power better and forcing you to pay attention to the wheel more, as the torque steer is more substantial.

I have taken a small road trip with it and driven everyday commuting around town for a few weeks now. I believe I have almost 400 miles on it. It seems to get more tame by the week, but I've been waiting for a final consensus because I want to reach 1000 miles before giving my final review.

If you want more info or detailed pictures of the mount, feel free to look at my install/review thread. Another member on here, [MENTION=762]BostonDriver[/MENTION], also has a Breedt mount and loves his.

You will have no regrets. Go ahead and install it. It was one of my first mods and I absolutely love it

Also, I like how you had the thread title changed after you realized you were wrong.

How old are you 12? Are you even old enough to drive a car? You like running you mouth hiding behind this forum. Nothing but one big fat purple people eater. If you don't have anything Useful to add to a conversation keep your mouth shut. I haven't changed any threads and until the company gets back to me I stand that the MAF sensor on the 2014 1.6 motor is more than a thermometer. I don't give a rats ass whether you disagree with anything I say or not. When you have the lifetime experience and have spent the money I have spent on modifying cars then perhaps you might be qualified to offer an opinion to me. Otherwise shut your pie hole.

A hack is someone using velcro on your sub install. Cat, kettle, black. Too lazy to do it right and make a kiwk disconnect mount.

I'm not sure anyone really has. The car handles fine without one. Maybe if your racing or motor-crossing then maybe there would be a purpose. As dyn085 is so keen to bring up on just about every subject I have not seen any performance logs showing that the rmm offers any real benefit. However if you spent !50.00 on a part that was suppose to offer benefit, and installed it, you would believe it offered benefit. No one on this forum has recorded any and I mean any type of chassis performance data to show without question that any rmm overestimate any true benefit.

Do you have the breedt rmm installed in your car? If not then I am not sure how you can dispute what I'm saying about what I'm feeling. At idle the entire car is shaking. Shaking like it has a cam on a 108 lobe sep. As for experience in this vehicle I'm not sure how you could dispute that either. At 166k miles, I know exactly what this car feels like with and without the rmm and I know it better than anyone else on this forum. if you are saying you have the breedt rmm installed in your vehicle and it is not shaking your car at idle, your fos. Everything in the car is shaking so much that you cannot see images clearly in the rear view mirror at a distance. the dash and stuff behind the door is rattling. Prior to installing the rmm the car was not making any noise anywhere in the car.

And for the others claiming you Have to break it in, that's like saying when you buy a pair of shoes you have to break those in too. that is complete bs. When you buy a paid of shoes they should feel good from the moment you put them on. If they don't you should not buy them. if you are having to break in a rmm. Then what would be the purpose? Once it breaks in its no longer offering the benefits it did the day you bought it. Rubber bushing wear out. So unless your installing an aluminum bushing, it starts to wear out from the day you bought it. in my case, 1500 miles a week, and I could not tolerate the bushing for 2.5 days and your telling me if I drive on it for 7 days, it will be supposedly broken in and everything will be great. Still fos. I don't mean anything negative by that comment, just stating a fact. It is not going to get softer in 7 days to the point that I can tolerate it.

 

[OffTheWall503]

You obviously didn't read my post, as I said a few times that I have the Breedt mount installed in my car. I do not experience any vibration at idle. Did you confirm you installed it correctly? The mounting bracket at the front portion has to be flush, and Breedt even states that in the directions. Did you ensure you torqued the two main long bolts at 50 ft/lbs? Improper installation can lead to unintended results. Take a look at the instructions and carefully read, if you haven't already.

https://www.scribd.com/doc/241919556/Fiesta-ST-Rear-Motor-Mount-Install

And concerning your post above...

1) Of course shoes need to be broken in; you mean to tell me you've never had a pair of shoes that started out stiff but softened up and conformed to your foot after wearing them for a few days?

2) 7 days isn't enough time either. I would say it goes by time or mileage, if you drive a lot of miles a day like you claim.

You seem to be the only one acting like you're 12, as you complete disregard others experiences with this product and bad mouth a product you don't fully understand in the process.

Improper installation can lead to unintended results.

And I did not read your entire post but...

Ok let's figure it out

Yes I buy shoes that are comfortable from the moment I put them on. Merrills

I avg 1500 miles per week. A week consist of 7 days. So which is it? Is it a time thing or mileage thing? Everyone here has said 1000 mile break in. I can do that in less than 7 days and do it every week.

Do you know what it feels like to be in a car with a 108 lobe sep cam? If you don't then the comparison means nothing. This would be a small ci motor. Like a 308. The higher you go in ci the more the lobe sep is absorbed. Everything in the car was shaking. Do you thing I just have it in for breedt and decided I would commit war against their business? What purpose would I have to buy the part type everyone recommended not brand but type and say it's junk? Not saying it's junk. It is a beautiful piece of machined aluminum. I wasn't experiencing any problems prior to installing a rear motor mount. But everyone said its a must have so I bought one. And I reported on how it felt. And I stand by what I said if you are running the stock turbo making 300 ft lbs of torque or less and enjoy the way the car drives you do not need to upgrade the rmm. It's an opinion. It's not wrong it's not right it's an opinion. Just like everyone else's opinion on this forum. Save dyn085 and data logging and a couple of guys who have spent stupid money upgrading this car who can say they have real experience in certain area and can speak on those areas it does not make them experts. It allows them to offer an opinion. Obviously there are somethings that are different in our two cars and there is a difference of opinion in what you call shaking and what call shaking.

 

[OffTheWall503]

It seems I am not getting through to you.

I am not experiencing this terrible shaking at idle like you are. And no, I'm not full of shit when I say that. You don't seem to be answering my question of whether or not you read the installation instructions and made sure it was installed properly.

I get it, in your particular case the upgraded RMM doesn't seem to suite you and your driving style. Some people will never need more than stock.

 

[dyn085]

I believe in another quote you made you stated that the engine never hits the firewall.

I don't understand why you quoted me to state that I've said the same thing before. The engine never hits the firewall, and I'll generally say that every time someone claims that their engine is hitting the firewall because it's a stupid pet-peeve of mine. It's pretty pointless for me to say it because anyone that thinks their engine is hitting the firewall should be able to clearly see that there's no damage to their engine or firewall, but I'll probably pipe-in anyways.

Why are you being so aggressive over an RMM discussion? Just because other people didn't remove theirs after two days doesn't mean they're full of shit nor does it mean they're as upset with it as you are. Vibration feel is a subjective discussion, at least it is in the way that we're using it, and just because you can't tolerate the vibration that what you feel doesn't make it intolerable by someone else.

And yes, an upgraded RMM needs some time to break in.

 

[Zerodameaon]

So you can hit 1500mi in 7 days, yet decided to remove the mount after less then half that? It's cool that you have a high milage FiST but that doesn't allow you to be a dick about it, especially when others have have done the same mod, and stuck with it for more then 3 days. You know what they say about opinions, I don't have to repeat it.

 

[frankiefiesta]

I don't think you know the car at all. Even driving it for 160k+

Insisting you are the most experienced when it comes to the car is a troll move. You drive it a lot.. Ok. Does ford change your oil and rotate your tires?

Stick to playing with sick speakers and awesome subs (cool dubstep brah) if you can't handle a little rattle when installing a STIFFER mount.
