Mazda Comp mounts are amazing. I could tell a difference right away (well... I did have a broken stock motor mount) and there is no vibration coming through unless your engine is on the fritz or in need of a rebuild... which reminds me.

Don't use hockey pucks. However, I did know a guy that used the window sealant stuff on his old motor mounts to stiffen them up. Worked out quite well and doesn't feel too bad.

Problem with Garfinkle's brace is it's FD specific...

Mazdatrix also sells a strut tower bar that has a torque brace but that thing is on the front...

With it on the driver's side the accelerating torque pulls on the bar and pushes on decelerating torque, isn't that better for a solid rod? I know some torque braces use hydraulic or gas pistons so to me it makes sense for those to be mounted to the other side, compresses on accel and stretches on decel.


I could see that happening, maybe.... the rubber bumpers on the RB bar mount will apply force over an area of approximately 1.5 to 2 square inches. Even making 600ft lbs of torque, the bar connects at what, 18" from the centerline of the e-shaft? That would apply 400lbs to a bumper against the sheet metal... I guess I don't know if that would be enough to tear it out, maybe after a lot of abuse. I'm gonna guess that if you're making 600ft lbs of torque with any 13B or a 12A you will already have something else figured out to keep your motor from tearing itself out of your engine bay, but I don't know.

So what I'm hearing is Garfinkle should start making FC versions, lol....

He said something about it long ago, but it never happened. Now he lives 40 minutes away instead of 2 minutes, and I don't know of any FC's where he lives now.

hockey pucks eh?

anyone up for a friendly game of hockey? mmm just reading this it makes sense to me about the top of the motor twisting, i didn't know that.. mmm learn something new everyday...

I dont want stock ones, and I don't want to break bank for solid mounts so within the next couple weeks I am getting mazda comp trans/motor mounts for when the motor/trans goes back in the car.

I had a broken P side engine mount too

i dunno, the reason I didn't get the Mazdacomp mounts was because the stock design which is prone to failing....

After a while I will report back on my banzai mounts, to see if I can give some insight.

Maybe because I own an N/A, but I've never heard the stock mounts are prone to failing. Granted, many of the stock mounts are bad on FC's, but they're also at least 18 years old and likely have over 100,000 miles on them. You'll be hard pressed to find anything non-metal (or metal...) on the exterior of the car that's in good shape after that long.

However, I would be more than glad if you could find some posts about the stock ones failing as I am thinking of replacing mine for peace of mind (although Kevin said they were fine as of 3 years ago on my 86 with 120k+ miles).

Not to mention, most of them are absolutely DRENCHED in oil. Which will swell and rot the rubber nice and quickly.

Well, one of the mounts on the thread-starters FC project car was done, and the other was better, but if you look close the rubber is always micro-cracked on all the ones I've inspected so far, including some I got with my short block.

Maybe it's because of owning a car with a REALLY sloppy drivetrain before( 1996 Mercedes C220) that I want to have my drivetrain "planted" and not move at all. Also big part is that I am planning on doing some drifting, and drivetrain slop really sucks for that.

I wouldnt say there prone to failing. max being micro cracked would fall under the terms ageing or weathering. im sure with 20 years of abuse most mounts would have micro cracks. And as far as the design being the same as mazdas oem. if its good enough for mazda then its good enough for me.
