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.

How the STI should have been delivered 3 months ago
NickZ
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

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).

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.

I installed these today since my engine and transmission mounts were super sloppy and holy cow. The difference is amazing. I feel everything at low rpm and idle which is awesome. The entire car feels so much stiffer than before. Just a little warning though, these are pretty stiff so if you want a peacefully smooth car at idle i'd look away from these. My car feels like a race car and I love it.

QUESTIONS & ANSWERS

  • Q: Mounting plates   Sensiman844 months ago

    Im swapping a Ver. 8 or 9 STi 6 speed into my 04 WRX and was looking at this set or the Perrin set of engine/transmission mounts. Would I require the mounting plates or any other parts to install this kit onto my vehicle?
  • Q: Durometer   LSUSTi4 months ago

    What is the durometer # on the bushings
  • Q: Difference   Nelson Asay11 months ago

    So I am kind of curious and I guess confused a little. What is the difference between engine mounts and motor mounts? Thanks RSD!

      A:  The terms are thrown around a bit but motor mounts and engine mounts will be refering to the same part.

      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.

  • Q: 2015 STi  Jimazz4 years ago

    Do I need to purchase the washers or anything else for the 2015STi or is this a direct fit? Thanks
    • 0 of 0 people found the following answer helpful

      A:  Nothing else is required for using these mounts on a 2015 STI and they will be a direct fit.
