go to mcmaster and order up some "flexible urethane"

Black 0.0005" 60A 1250 25 1

Black 0.0005" 94A 3120 25 1
8644K18 $26.92


60a is aprox 2x stock .(stock is ~30-40a hardness)
80a is aprox 2.5xstock
94 is rock solid **** .. some one try it and report back on how stiff it is and how much vibration at idle and shifts u get with it

u mix this **** . all of it .. and pour it into your motor mount . thers cavities in most mounts and allow play . this will stiffen it up alot .
its been done befor over on vwvortex . dunno about hear .. i only seen ghetto window urethane mounts here . the mcmaster stuff is the **** . whont fall out or detieriate

Funny, I read it as "solid" and didn't even realise your mistake until I read this post.

 

yup i also read 'solid' for some reason.

So what's wrong with the 3M window urethane? I just did the exact same mount (passenger side rear) for some kid. I built it up quite a bit more than you did and it worked wonderfully. I'll have to try the mcmaster stuff some time if it actually is better. For reference I think the 3M stuff is about 60a going by your description.

if its the same 3m window **** i think your talking about . comes in a tube ? .
that doent even come close to this stuff ..
my bud used the 3m window stuff .. and u can easly compress into it with your finger
i used the 60a befor and u could bearly distort that .. i used 80a in the pic ..

 

i completely striped out the oem rubber and refilled the hole mount with the stuff .. (reused the bolt mount tho) .. and i only bought a 1lb kit .. wasnt enough .
also i had some leakage from under the tape i used to seal it .. so it whent down a little aswell ..

REAMOVING ALL THE OEM RUBBER IS NOT NESS NOR BENIFICIAL &gt;&gt;&gt;

i did it b/c my sht was shot .. and falling aprt in chunks

 

huh, well the stuff i use is about twice as hard as a honda mount and probably 120% stiffer than the mount you have pictured there. But i guess doing a rockwell test with my dirty *** thumbnail isn't very scientific... I did it on a VW mount that was only a few months old (check my post in this forum for turbo pics) and it worked great.

HAH me too. Weird. Anyways

 

How much of this stuff is 27 dollars worth?
Do you have a pic of the container so we can get an idea of how many mounts one could fill with this...

 

This post reminds me of this post from vwvortex

the 27 is for a 1lb kit .. it will do 3-4 mounts whit out u reamoving the oem rubber .
if u reamove the rubber i say like 1.5 mounts ...

Everyone is ahead of us honda-tech guys :-p

 

Which mounts do you do? All 5 of them?

5 mounts? what kind of car do you have? My honda only has 4 :-(

 

the dc-2's have 5 mounts including the a/c bracket thingy.

problem is, you still have the stamped steel that its all attached to. cnc machined Al. is going to be stronger but obviously alot more expensive.

not a bad mod for something cheap.

oh yeah, if you end up using too stiff of rubber, can you just drill holes or tear more stuff out? then repour the mounts with a more flexible rubber?

 

I am gonna attempt the front lower mounts and the trany mount or whatever is in that link over spring break. I will photo document it, let everyone knoe how it went. Can you get that **** at home depot or something?

 

That's a good trick, I did this with the 80A a year and a half ago on my lower mounts. The car shakes like hell at idle but damn what a difference with wheel hop and overall vehicle response

 

ill probably end up doing my mounts with whatever is the softest urethane I can find (somthing softer than 60A- I hate vibration)

 

i used 3m window weld on my front tq mount and the side two on my d16; that **** is stiff as rocks. A lot of the rubber was gone so they're pretty full. And it took about 3 days for them to dry enough to put them in the car. They haven't leaked yet and by now i'm sure they're 100% cured

I wished i would have used the 2 part urethane stuff because i'ms ure i got air bubbles in there. We're fixing to urethane my friends mounts and we'll be using th e2 part with that.

 

wow, I may just be ordering some of this stuff today!

Thanks!

 

i'll probably try the 94a here once i get all of the parts for my bottom end together. I have a 99si and i have the 5 mounts, the crossmember mount, the passenger side mount, the ac mount and the upper drivers mount.

Heres my question... is that ac mount required when i fill my mounts?? The reason i ask is beacuse when i pulled my ac, i pulled that mount and within a few days i tore the upper drivers side in half, so with filled mounts could i just leave the ac mount off?

 

So what mounts do people usually do with this? All of them? If not please explain because one of those links they only do the lower mounts....

I did mine with this stuff first also. Filled the whole mount and heat cured it and waited days. It still never fully cured, so I cut it open and the core material was still liquid. I think it will only fully cure up to a spcified thickness. WHat that thickness is, I don't know. SO then I redid it but I did it in layers and waited for each layer to cure. It was a multi day process. I wish I had seen a thread like this before I did what I did.
