Between Cusco and STI motor mounts...
 

Any input as to why one would lean towards one as opposed to the other. Cusco is slightly less expensive but is supposed to generate more vibrations. The poly seems more robust than the STI mounts, though.

STI is obviously subaru approved and should be slightly better to live with day to day. The vibration issue isn't a huge deal, honestly.... just looking for other's input.

Thanks!

I have the sti engine and trans mounts and they are stiffer than what I usually think of when it comes to rubber bushings. Great upgrade, and I wouldn't want anymore stiffness than what they provide. That they use OE-quality manufacturing is icing on the cake.

What's wrong with the mounts that are in your car ....... did the massive torque load pull one of them apart .... ??

:slap: - humfrz ...... go take a nap.

Doing overpipe and frontpipe soon with an SC to follow. Just preparing.

You'll notice the change with the STi mounts when you want to... Not idling at a light when the SO says "your car is running really rough".

My midpipe was hitting the rear subframe under acceleration stock, not with STi.

I got the Cusco one cause it was cheaper. I don't really notice it at all anymore.

Cusco mounts were recently put on after 95k miles on the OEM mounts. My engine moved so much on the OEM mounts causing my turbo kit's downpipe to knock against the frame. Absolutely no touching or movement at all with the Cusco mounts. There's a considerable increase in vibrations when taking off (but doesn't bother me at all), a minor increase at idle, and i can't tell a difference at all while cruising.

I am slowly leaning towards the cusco mounts. I also have their transmission collar....so... why not, lol.

The STi mounts are nicer for a car that is daily driven, and worth retaining a bit of comfort in my opinion.

I've found through the years that if you touch more components less you can often get a 'package' that is greater than the sum of it's parts.

A lot of people do solid motor mounts with stock trans mounts, and end up with tons of vibration and say there's no way they'd want to add more by doing the trans mounts. If they do STi motor mounts, and a whiteline trans mount insert, or a similar setup it's often more livable, and 99% as performance oriented.

Just my opinion, there's no wrong way to do it, just different ways.

What about the Perrin mounts? Anyone used those?

I am sure this is not a common occurrence, but there is my reasoning not to go Perrin.

I use the STI mounts, perhaps my stockers were going to hell, because I actually find that the car is quieter with them. They are fine and work well, it's not a night and day difference but you feel a noticeable difference in throttle response and an overall 'tighter' feeling all around. I'm happy with them.

The difference between the two is that the STI was designed with a street car in mind, so there's a lot less NVH (especially at odd RPMs).

If you want to minimize random rattles from inside your car as you drive, go with STI. If you don't care, go with Cusco.

Just installed Cusco mounts a couple weeks ago prior to installing the turbo. The only negative aspect, in my opinion, is a bit of vibration while taking off from a stop but I fully expected that to happen. The biggest improvement was that it really took up a lot of slack in the driveline and made a big difference in on/off throttle response. Well worth the upgrade, imo.

So the biggest perceived difference is vibration at take off? Interesting. I've installed the perrin transmission mount along with whiteline kits KTD 922, 925, and 926, and I also experience more vibration on take off. With the cusco engine mounts do you think this would increase, decrease, or stay the same? Might as well save some dollars if I can

I second the STI mounts, based on all my research that’s the route I’m going for my car based on how I use it.

i have these hardrace mounts, and i can report they work fine.

Yes, that was really the only noticeable difference to me. I have the Perrin transmission mounts too .. those added a bit of noise as well. The motor mounts just amplified the rigidness. You get a better sense of what the clutch is doing in my opinion. It's a welcome addition to the added horsepower, plus I was in there anyway with a decent amount of miles on the odo. Please understand this is no longer my daily driver - I don't want to mislead you by saying "they aren't too bad." I would probably go with the STI mounts for a DD.

I see. Thanks for clarification

I'm looking to get either the STI (part # unknown) or TRD mounts (12311-ZN600 / 12315-ZN 600) ASAP and can't seem to find them in stock in the U.S. anywhere. Where were you buying yours? I might have to find an importer at this point.

ajh88: Saw STI engine mounts in ft86speedfactory shop

Unfortunately they are back ordered and no ETA on availability.

I have STi mounts, and I haven't really noticed a difference from stock in terms of vibrations.

Googled a bit around. STI's part numbers seem to be ST41022AS000 & ST41022AS010
For example on japanparts.com, here are TRD, and here STI. Overseas shipping might take a while though.
You can try googling for part numbers to maybe find some closer shop with them in stock.

Thanks for the heads up on the STI parts number. I see them (TRD) listed on RHDJapan as well. Tomorrow I'll give Jesse Streeter, who i've used before for obscure oversears imports, a buzz and see if he can get em to me faster.

I've got an ACE header and ecutek tune to go on and am waiting on the mounts now... which should mitigate any overpipe contact.

I guess I bought the last set of STI mounts from FT86SpeedFactory. It shipped out today hehe.

When did you order it? I ordered mine two weeks ago and was told there was no ETA on when it'd be back in stock. Rest of my order shipped but that one was shown as "ships from factory" meaning not in stock.

Just got home. I ordered it over the weekend with a tons of parts and it was on the shipping list as shipped today. One other item shipped separately from the factory a few days ago, but it was something different in that same order. And one item has yet to ship. I guess I'll find out next week if the motor mount is in there or not.

Finally did this. Chose the cusco mounts because I had the trans collar. Did a diff brace at the same time. I was NOT prepared for the vibration on startup and takeoff, lol. I only drove about 50 miles on the highway so far but the car definitely smooths out as you get up to speed and feels tighter overall. I'm sure the mounts will break in a little over time but I may wind up swapping them out, not sure.

It's been a while, but life happened and a lot of things have prevented me doing a lot with the car. Hopefully I'll get back in to the hobby more in the next couple years.

I have sti mounts in now. And i got cusco mounts on order coming soon. Sti mounts with FI feel like oem mounts. Great option for NA though.

I’ve read the cusco mounts should fully break in after about 200miles and not be as harsh. Either that or maybe you just get used to it after 200 miles.

Yeah, either way I guess I just have to drive it, lol.

Does anyone know if there are any differences between the STI and the TRD motor mounts?

Sorry for bringing this thread back to life
Gotta ask, I am favouring Perrin engine mounts as of now. However I have seen some threads that say the bushings on it melt from aftermarket header heat. Since then Perrin has updated their motor mounts. Has anybody had this issue with updated Perrin mounts?

The new perrin mounts aren't supposed to have the issue. Whatever you do, unless you are tracking this car don't go cusco. Im swapping them for STI mounts and a kartboy trans insert after about 800 miles of driving. I did a roadtrip in the car and I can't take it. I'm old and they suck.

Nope! No issues on the new ones that aren't prone to melting. Slightly more vibrations than stock and sti, more noticeable when its cold out. STI is pretty much like stock

I will be selling mine soon if anyone wants them I will post a thread later this week
