1 new mount, 1 original that was still fine. (i guess only one of the mounts wearing out is somewhat normal)

still some shifter movement even without boosting on my untuned car.


i'd love the brace and a diff brace too but it's way down on my list of needs.

how do those side plates mount to the fender? it's not like you can get a bolt on the back...

That's not where I got it from

bigmack000

when its time for you to pull the motor that is when all the mounts and stuff should be done. i could never afford it before but i knew mine weren't the best put now that i am getting a rebuild. i will replace them and also get the brace cause that lil extra is always worth it the brace will jstu make the mounts last longer . oh yeah where did you get yours from ?

I got it from a guy named David Garfinkle, in Nashville, Tenn.

I liked his because the mounting plates are thicker and rod was custom made just for your car..

i dont think i have ever heard anybody claim that an ETB was their fix for a bad motor mount.

PEOPLE. . . LISTEN. . . nobody is telling ANYBODY to put this on a poorly mounted car. not one person has said, "my engine was shaking all over the place and i slapped this bad boy on. . . voila. . . its all better." everyone that puts one on says things like, shifts better. . . feels better in a turn. . . etc.

i love the fact that there are some people on this forum that just cant be happy with a product unless they had a hand in it.

Mine only have 40k miles, and I still wanna replace them

I didn't know Garfinkle was making IC inlets.. Hmm.

Also, do you know if JIM's still making those bushings??
is it nice??

Jim, do you still sell them?? I might be interested..

Paul,

You are correct about that.. I haven't read any in the past about people using Torque braces to avoid getting new engine mounts..

I certainly didn't get these because my engine mounts were bad.. I like how the car feels now.. and wished I have done it earlier.. For that reason, why I'm posting this thread.. to give some feedback..

jimlab

Bullshit. You know damn well that there are people buying these things to slap on cars that have the symptoms of bad motor mounts, but they're too lazy or not knowledgeable enough to check or replace them. Next you'll be telling me that Garfinkle wouldn't sell one to someone unless they'd first checked their mounts to see if they actually needed it...

It's nothing more than a Band-aid for the weak stock motor mounts. Have you ever seen a car issued from the factory with a "torque brace"? Do you see other cars with even more horsepower requiring a "torque brace"? I rest my case...

Shove your opinion up your ***, Paul. I'll be more than happy to lend a hand with that...

Jim,

why are you so negative?? Almost all (emphasizing almost) the threads that you post are pretty negative..

I know its your opinion.. and you want people to listen to you.. But fact is that its a cheap resolution to what could be a bad motor mount.. So, what is the big deal if it is in fact solution for it?? You calling it band aid makes me think that I have just wasted my money on this item.. Which I personally think made a noticable difference.

jimlab

Sure it made a noticeable difference, but if it's masking another problem, it's a Band-aid fix.

It's far easier to bolt something new (bling bling!) on the top of the engine than it is for someone to take the time to check the motor mounts for damage and replace them if necessary. For someone to insinuate that no one EVER installs one of these torque braces because their engine is shaking or their shifter is flopping around is asinine. Of COURSE people do it. It's the path of least resistance and the easiest "solution" to the problem.

Worse, for someone to specifically state that "some people" are only mentioning this because they didn't have a hand in making it is bullshit. Pure bullshit. I can read between the lines. "Some people" = me. Next someone will call me a "hater" for not just going along with the flow like a good sheep...

What you call being negative, I call being a realist.

Herblenny

well, my mounts were good also.. L

jimlab

If there's a benefit to installing a torque brace, it's because there's a problem with the ability of the stock motor mounts to control movement of the engine, even when new.

What I stated was that a torque brace can mask a problem with the mounts and I know human nature well enough to know that some people will take the easy way out and install it to solve the problem. To say they won't is ridiculous.

Perhaps it just takes someone who doesn't have a vested interest in selling one or in justifying their purchase of one to state the obvious?

Jim,

Can you explain to us what some of the negative side of having bad motor mounts.. I'm a newbie in this matter..

jimlab

Do you mean like giving the motor a nice long pry bar to work on fatiguing the fender support with if worn or damaged motor mounts allow too much movement?

Herblenny

iTrader: (13)

Come on Jim, I'm talking about without the Torque brace.. what are some side effects of bad motor mounts?

jimlab

In stock form, the entire drivetrain is supported at four points; two motor mounts, and two differential mounts. If the mounts fail, it allows excessive movement (and stress) along the entire drivetrain structure. The movement of the drivetrain can contribute to missed shifts (2nd to 3rd, especially) and damage to the transmission. It can also contribute to wheel hop, leading to damage to the differential and rear suspension. Eventually, a sloppy enough system could result in a cracked or broken PPF, and undue stress on the case of the differential and transmission, which could result in stress fractures in either. Hard to say where it could end if let go for too long.

rotorbrain

jimlab, i have had nothing but respect for you. . . in the past. i made a point not to call any names out because i thought that was against the rules of the forum.

your statements are slightly true. the ETB is a fix for poor mounts in the fact that the stock mounts arent exactly up to par for higher horsepower. id much rather check my stock mounts, replace if necessary, and ADD a 100.00 part rather than WASTE money on solid mounts or expensive urethane mounts. are you paying attention? your blind comments cause threads to stay alive for way too long. i dont care if you do have "plans" for a v8 powered rx7. your cars been down longer than mine!!!! where is your place to stand "mr. guru"? i dont care how smart you claim to be. you can post about higher horsepower engines not needing an ETB all you want. there is PHYSICAL PROOF from buyers saying that THERE IS A REASON!!! most of those HP monsters have very solid mounting.racecars HAVE to be well mounted. less engine movement means quicker response. i seem to remember seeing the shadetree mechanics put chains on their mustangs engine.EVERYBODY UPGRADES MOTOR MOUNTS. . . WHY NOT ADD ANOTHER? the rotary engine only has four. . . two at the engine bay and two through the drive train. the ones on the rear-end arent really even enough for me to count. theyre a whole car length away and there is too much linkage between the engine and the diff. there are no mounts up high. why is it that honda motors that ive come across have three engine mounts in the engine bay? ive seen them down low, up high, etc. . . BECAUSE MORE MOUNTS MEANS MORE STABILITY!!!! how thick is your skull? you gotta be able to understand this. its only so simple. youre doing the most extensive v8/rx7 swap in the history of FD's as far as i know. ive READ about things and said, "wow, that guy knows what hes doing." youve talked about how proper mounting needs to be accomplished on your car. why in the world is BETTER mounting such a hassle/problem for you and our lowly rotary engines?

i dont get it jimlab. . . you must be too smart for your own cause. you cant accomplish everything by yourself mr. labreck. your arrogance is worthless in this argument. . . face it. . . your participation in this thread is pointless.

paul

oh, i just realized that you called out david garfinkle as well. well, i take that personal. he not only is a great and honest mechanic/businessman, but hes a DAMN good friend of mine. hes been nothing but great to me and im sure everyone thats been to his house can vouch for me on that. . . most of those guys have seen my car that way. you have made a blind slander against a man who has done nothing to you. he is always out to better his name in the world. he tells people that if they arent satisfied they can send it back. he doesnt even charge until satisfaction is reached. he speaks at a personal level with ALL of his customers. . . and all of his customers (no matter what they bought from him) WILL agree with me. i have no doubts about that. you need to check yourself mr. labreck. im checking you, i know that much. . . and you have soured me to anything that has to do with you. . . and you can talk about shoving things up my *** all you want. . . it just shows how much you want to touch it. . .

These solid mounts cost about $400. About the cost of the stock rubber mounts. How is that a waste of money if they cost nearly the same as the stockers and will NEVER wear out?

How much more stable than solid mounts do you want? I will be replacing 2 pieces of rubber filled with goo with 2 solid pieces of metal. Exactly WHERE is the engine going to twist at being bolted literally DIRECTLY to the subframe and the tranny also being bolted directly to the body via the tranny brace?

Even if I didn't add the tranny brace, the solid engine mounts prevent the engine from turning side to side. Thus eliminating the need of any additional engine bracing. It's not like the solid motor mounts are going to stretch out far enough to allow the engine to move around

Honestly, your BECAUSE MORE MOUNTS MEANS MORE STABILITY! comment for this application with solid mounts is almost like saying "I need 3 strut tower bars"

rotorbrain

flyebye. . . youre mistaken. . . metal on metal WILL wear out. time will prove that and vibration will be the key. not to mention the stress you place on the rest of the frame/body.

having solid motor mounts isnt the key for a street car. you can deal with that all you want.

you screwed up with the last comment. the axis for movement on the strut towers are at the top and bottom. by adding another you would only add weight. so. . . nya. by adding another motor mount at the top of the engine you stop the "roll". take this for example. . . get a buddy of yours. stand with your heels connected. have him push you. . . record the results. then take a step back with one foot. have him push you again. . . record the results. NOW, keeping your feet separated have him push you at your head. record the results. THEN, put your hand on a wall behind you. have him push you. . . record the results.

More stress on the subframe, true, but not to the extent where I would have to worry about it especially since the FD isn't daily driven and I probably don't even put 100 miles on it during an entire month.

Yes ROLL was the word I was wanting to use, but it kept slipping my mind! That is the main purpose of the solid mounts...which is to prevent roll. What is the purpose of the engine brace? To prevent roll.

But....added torque brace using stock motor mounts....now think about this for a second....you now have a solid bar holding the engine on one location, and little rubber goo filled thingys holding together the other end of the motor. Can we say......weakpoint?

IMHO, I just feel the solid mounts completly eliminate the need for the engine brace since they ARE doing the job fo the engine brace by preventing roll.

Man, This thread has gone to another side.. Come on.. First of all.. I want to point out to you that I am not an expert.. Nor am I planning to build a race car to drive on the street.. Nor am I a teenager who wants to go race every car on the road..

What I know about solid mounts are and other 7 owners have told me is that they cause more vibration than norm. Since being solid, vibration travels thru the car..

Would I want that?? NO.. I want some crisp shifting but I don't want something clunking all the time..

I see this brace as a good alternative to Solid or even Brand new mounts.. IF you have good condition mounts.. Which I think I do..

And by theory, if you are going to replace your stock mounts, the torque brace will help its lifespan of the mounts.. So, I don't see any disadvantage of getting these brace..

As I pointed out earlier, I recommend Garfinkles because of its quality.. Look at the mounting points, look at the thickness of the mounts,.. over all this is far better built than anyone elses..
Like Strut tower braces... you have many many choices.. Some pay 10times more for better constructed brace.. Carbon Fiber, Aluminum, Stainless Steel, whatever.. Around 100 bucks.. It sure was worth it.. Why don't we go yell it those kids who spend 100 bucks on stickers.
