Features & Product Details

Cusco is one of the pioneering companies based out of Japan that has invested countless hours of research, design, and engineering to develop quality suspension and performance products that will improve your driving experience. Some of the fasted cars around the world who compete in time attack, time trials, and other racing avenues will more than likely have a Cusco product on their car.

These components are the Cusco Engine and Transmission Mounts designed to reinforce the engine and transmission to help reduce movement. Your OEM units get the job done, but like all components that have bushings, eventually they will become weak or wear out over time and mileage, and this is especially noticeable under high-performance driving conditions where excessive movement of the vehicle can cause jarring movements in the engine and drivetrain. 

Note that these are much more solid when compared to the design of the OEM units, which makes for a better option for those of you running more power and a more aggressive suspension setup. However, this will create louder engine and transmission noise in the cabin. 

Comes with 2 metal washers that are used to provide extra clearance with the cross member on some models.

Holy cow....(2017 STI) 1 month ago
5out of 5stars

I bought these last week and installed them the other night and holy cow. Well.. let's start from the beginning.. the reason I bought these is because after a hard launch I heard a loud pop and couldn't figure out what I broke. I noticed a little more vibration than usual and after popping the hood, I noticed the engine was tilted to the left! 😵😵😵 The only thing I could think of was a broken mount. I figured, since I'm replacing the front mounts, I figure I'd buy the value pack (motor mounts and tranny mount) and replace it all. Come to find out, the passenger side wasn't low, the driver side was high! I'll attach pics so you know what I'm talking about. Anyways. This is why I bought them, or else they wouldn't been last on my list. Moving on to the parts and installation. I have a mechanic background and have changed mounts before but never on a Subaru. My total time was about 6ish hours, although, if you're familiar with the whole thing, then you can do it faster. I was also in the garage on jackstands, so there was a lot of crawling around.. also, I wanted to go slow so I didn't break anything. Thestructions aren't in English so forget about those. I actually found a forum that helped me out and if you follow it to the Top, you'll be ok! http://subaruidiots.com/motor-mount-install-for-subaru-impreza-wrxsti/ Honestly, nothing was "difficult". It's all pretty straight forward. The only reason it takes so long is because you have to remove the intercooler and unbolt the front of the pitch mount and move it up. Then when you go under, you need to remove the tray and another bracket which is about 10 bolts. Then unbolt the away bar and move it out of the way. Unbolt the bottom of the mounts and start jacking it up. I followed the advice of others and used 2 Jack's with blocks of wood. One under the oil pan and the other under the tranny pan and jacked them up one after another so that I not only had the security of knowing I'll be ok if one fails, but it's less stress on one single point. As you're jacking them up, check out the posts on the on the mounts on the car. You'll notice they're lifting. Jack up the engine high enough to where you can remove the bolts in the front (both driver side and passenger side FRONT BOLTS are easy to get to. The pack ones are a PITA!!! I used an open ended wrench with another connected for leverage, however, like one of the other reviewers said, use a wrench with a rachet and your life will be Soo much easier!!! I promise you. Lol. Check that other post as I can't recall if it's a 12mm or a 14mm. Once you get those mounts out, they literally fall out. Remember the order that it comes out as you're gonna reuse the shield. Match the new mounts with the old and replace them. (If you put them on backwards, it will not fit. ) Once that's done, and they're torqued down, throw them on and move to the next one and repeat. Like I said. The ONLY main issue I had was the back bolts on the mounts. So do yourself a favor and get the rachet. As for the tranny mount. Unbolt the bottom of the mount and you'll see the tranny start lifting. Once I was able to wiggle the OEM bracket around I thought I was good. Nope. You have to keep lifting everything until it slides out. Once it does so, then you're good to install the new mount. Before installing. You MUST remove the top part of the mount in order to get the bolts through. You'll see when you get your hands on it. Once torqued down, then slide the top half on and tighten the 2 bolts. Here's the fun part. Making sure everything lines up as you lower it. SLOWLY lower the Jack's until you see the tranny Mount bolts barely touching the frame. If it's not lined up, get a wrench or screwdriver or anything that can fit in the holes of the new tranny mount and use leverage on the frame to adjust the bolts. Once it moves a little, lower it a little more and readjust. They will eventually line up. Once they line up, lower it till they sit in and torque it down. Now for the engine mounts. Start lowering the Jack's little by little until those bolts line up with the holes. Fortunately, I didn't have to adjust the engine, so as I was lowering, they fell right into place. Once that was done, torque em down and you're good to go! Make sure you bolt everything back together and don't finish with extra bolts. Lol. Not on to driveability. Words can't explain how it feels.. it's going to start up and shake a little then start purring. You WILL notice some NVH but let's be real. When people say it's super aggressive, they're being sarcastic. You're in a car not on a rocket. (Although it feels like one lol). It's going to vibrate more than usual but not to the point where its crazy shaking. OEM I give it a 3 out of 10 on vibration, these I give a 5 MAYBE a 6 out of 10. But here's the awesome thing. I'm stage 1+ with nameless deletes and for some reason the car feels like it has a slightly deeper tone. (Maybe it's just me.) When you drive it, you'll immediately feel the difference. Power just feels more..."instant". If you don't already drive the crap out of your car. You're gonna want to even more because of how good it feels. Shifting even feels better! Bottom line. Nike..just do it. It's a pain to get the back bolts off but once you replace them, you're not going to want to get out of your car. A little extra vibration but who are we kidding. You bought the car for what it is. Not because you needed an economy car. This replacement will only be more of a reason for why you bought the car. There's more expenses mounts but whatever route you go, they're going to be 10000x better than OEM. get them or any other mount. IDC. You'll love them. PS. Check the intercooler, turbo, and TB for oil and remove it. It'll make you want an AOS. I got oneof those also. Time to install it!

How the STI should have been delivered 8 months ago
5out of 5stars

Car Use / Review Point of View: 2018 STI, Daily Driver + weekend canyon carver, ~Stage 2 power levels. Product highlights: Fit/Finish is superb. Finish is Durable powdercoat over steel. Hardware studs are solidly pressed align perfect with factory mounting points. Connecting hardware is robust and locking. Included are spacers to adapt the transmission mount to work with a 5-spd (if so equipped). Rubber bushings look extremely high-quality and consistent throughout. Durometer of rubber is quite stiff, but breaks in over a few weeks. Install for motor mounts / transmission took myself ~6 hours. Moderate shade-tree mechanic aptitude. A ratcheting 14mm box-end wrench made the world of difference in installing these. Performance: This is the way the STI should have been spec'd from the factory. It eludes me why Subaru would design such a stiff, firm, responsive chassis and then connect the drive-train to it with just hopes and dreams. These mounts firm everything up to a point where the car actually feels like it's designed to work together. Vibration and Harshness are negligible from stock gummy-bear mounts. Noise did increase a moderate amount. Gear whine is prevalent in gears 1-3 at

Good Product 10 months ago

Pretty simple to install. Was able to google the instructions to get them in English. To me, I didn’t have much more NVH than I had before (shifter bushings were already installed before these).

cusco engine + trans mounts 1 year ago
5out of 5stars

installed on 05 STI transmission + differential whine is definitely noticeable through all gears from 20-65, so if you enjoy your quite cabin, these mounts are not for you. slight increased vibration at idle but who cares other than that, slam shifting gears is way more smoother and the car definitely has a big difference when you drive it, overall i would recommend it.

So I've had them on for close to 1 year, paired with a Perrin dogbone and SuperPro crossmember bushings. 2002 WRX, around 250HP at the crank. Tbh, I was expecting them to be a lot stiffer, but they're quite comfortable. No extra NVH at all. Obviousely, the engine and gearbox assembly no longer jumps around like a dog on a leash. Bottom line - just perfect.

      A:  If you are fortunate like I was (original owner of 06 STi), my shop told me that I didn't need to buy the earlier mounting plates. I had a late 06 production STi, that did NOT originally have the liquid filled mounts installed. They just swapped the parts over from my original mounts. If you are doing it yourself, maybe it's worth just buying the plates to avoid the hassle. But my shop had enough experience installing them that they told me in advance.
