Ron K Miller. Just a note , Garfinkle has a 1990 BMW K1 ,the 16 valve go fast, not a k 100. It does not have a steering damper . interesting but only 600lbs , 155 mph ,still stock

For those of us who have almost doubled the stock hp, it does wonders, because the stock motor mounts were never made to handle 400+hp. You should see what happens to my shifter in 1st gear without my brace and you would understand.

i have the garfinkle unit. its amazing. david garfinkle has had his on his car for quite some time now. the bushings arent going to go out. they would go out with a lot of wear, as would any other rubber bushing. i doubt they will go out anytime soon. make some inserts out of polyurethane if you like. they will last and if you like, david can make the bushings thinner. . . they transmit more vibration, but keep the engine a little more stationary.

the thing you were talking about with putting a rubber piece behind the fender mount. that wont do too much to help you. what happens when you do that iiiiiiiiis, you compress the rubber slab to the point at which it will no longer dampen. so all you have done is make a thicker mount. . . with some ugly rubber bulging from the sides. the garfinkle unit works. . . its by-far the best bang for the buck (in my opinion, superior to all others) ETB on the rx7 market today.

here is the thread of the DIY mounts:

how about this for a reason. . . 2 points create a line, while 3 points create a plane. which one do you think moves less?

it has been explained several times. . . putting a rubber piece between the mounting bracket and the fender wall compresses the rubber slab. the bolts you use tighten down on the the rubber. . . IT DOESNT WORK AS A DAMPER AFTER THAT. the garfinkle piece uses bushings and a link correctly sized to the distance from the fender to the UIM and if the engine sits further back or forward the link will be made accordingly. . . like mine.

I have been using the brace I sell for a while. NO Vibration. Does a great job.

""piece uses bushings and a link correctly sized to the distance from the fender to the UIM and if the engine sits further back or forward the link will be made accordingly""

I dont understand when you say "will be made accordingly". Is this something you adjust on the car if the motor is further back?

damian,

My motor mounts are relatively new, so the brace is being taken as a measure to preserve those mounts etc (for now at least). You make a good point though, and after reading that thread, I believe I will look into some urethane motor mounts down the line- the best part being I can make them myself. At the end of the thread, you posted some updates on the feel/vibration with the mounts, are they still accurate? https://www.rx7club.com/forum/showth...s&pagenumber=4

Thanks for the heads-up.
i see ur point in saving the new stock mounts life by using the t-brace.... good reason.

the DIY urethane mounts have been kick azz, another (and very picky) local fd guy drove mine and wants to do the same mod to reduce shifting slope, ..... and now i dont even notice any vibration and the engine is solid as a rock in there when i rev it up, feels great at the track too. i think if i were to install stock mounts i would do a t-brace to mitigate the extra movement the stockers allow

good point paul, however if two point dosnt move, why add a third? , what i mean is with the urethane mounts my engine dosnt move much at all, so a t-brace in my case would be overkill.... however stock mounts are wnother story...

Wow, more E-bay bullshit:

"Not only will it reduce wheel hop but it will also extend many parts of your car such as your exhaust system, as the damper will take the violent jolts that will eventually wear out your exhaust systems joints. "

I've been VERY concerned about my "exhaust system joints" lately.

Next thing will be horsepower claims.

Why the flame ?

Is not BS, possibly hype. Reducing the excursion of the exhaust system when shifting is one reason for buying one. My cat use to bang the underside on hard shifts.

I was just asking if we had any users of this particular product.

He isn't flaming you. He is flaming the description used for the particular product.

Exhaust systems don't have "joints". They have hangers which connect to the car via "rubber donuts" or "exhaust hangers".

Some exhaust systems do utilize flex joints. But, for the FD, I have never seen an exhaust system utilize a "flex joint" (but I could be wrong).

Your exhaust system issue is possibly due to old rubber exhaust hangers, or bad motor/tranny mounts, or ...just plain bad fitment.

Also, "Reducing the excursion of the exhaust system when shifting"...I have no idea what you just said.

My exhaust system has 4 joints.

Did you smoke all of yours.

joints = connections = every place you have a gasket

My issue was due to a DP that was not perfect. Almost impossible to fix except by replacement. The torque brace reduces the range of motion of the engine. This keep things from bumping things they shouldn't. Those bumps put big loads on the parts. (I used smaller words just for you ).

Ron is the guy that doesnt uderstand how the brace helps in the first place, so I should have realized it is hopeless.

My hangers were all new BTW.

I've never used "joints" to describe the particular gasket locations that you are talking about. But, I know what you're talking about now...

I've had the garfinkle brace on my car for about 6 months and love it, as paul said, the link is custom sized for your car....bottom line is the thing works

upgraded motor mounts are a great idea, but I didn't feel like installing them and this brace should preserve my stockers indefinitely

garfinkle's braces are made to fit for each individual car. he sends you the two mounting brackets/pieces, you get the measurement he wants, and he makes your brace/rod/whatever you want to call it, accordingly.

why?

Yeah, not flaming you at all - I just got a laugh out of the product description on Ebay - it's pretty funny.

About the ONLY thing anyone has ever claimed is that is tightens up the shifting (which it does). If your motor mounts are worn out you could put a stick in between the frame and engine and it would help. Hmmm. maybe I'll go down and get a nice 1" dowel at ACE,some aluminum spray paint and a couple of bolts, and sell it on Ebay for $50.00!!

In my book, BS = hype = wild claims.

without hype and BS, where would advertising in general be in this world?
