The CorkSport Advantage

Perfect Fitment

The CorkSport Mazda 3 Rear Motor Mount is designed to fit and install like OE. No worries or extra parts to take your Mazda to the next level.

Design Focused

The CorkSport Race RMM combines the proper materials and design to create a motor mount that provides great performance and daily driving tolerance. The billet aluminum body is lightweight, strong, and durable with the black anodized finish.

Polyurethane Performance

Through testing and tuning, multiple durometer polyurethanes were tested to determine the optimal stiffness for performance and comfort. Durometers ranging from 60A to 90A were tested with the final result coming to 70A for the right compromise of driver feedback and daily driving comfort.

Strength In Steel

In order to properly install and torque the performance rear motor mount, precision machined black zinc coated steel sleeves are used inside the polyurethane to allow proper bolt torque to be applied.

This part is a must have if your looking to better your Mazda 3s performance. Vibrates A LOT when A/C is on if not theres not too much vibe. Very happy with this upgrade and for what its worth it is the best mod so far.

i noticed the difference RIGHT AWAY at start up with this mount.. some added vibration (to be expected). the benefit is - MUCH crisper acceleration. less flex of drivetrain results in more immediate response.. overall feel is nice and tight. install was easy and directions were perfect. nice inexpensive mod that only the driver will know.. keep it sleeper. thank you corksport!

Bought this rear motor mount, the mount failed after only 2-3 months of use, the urethane teared around the sleeve. Got it replaced after an incredibly long wait (4 months), now to need motor mount is on the car and did not failed yet. Other then that the mount a pretty stiff, vibration is increased by at least 200% so if you dont like vibration this is not for you. Shifting is WAY better now, and i recommand you buy this mount.

Mathieu 02/14/2017, 12:23 PM

Nicely made part but far too much vibration at idle (both with a/c on or off) so i drilled 6-8 decent sized holes through the polymer to remove some of the material and give it some room to move. Still much stiffer than the factory Mazda mount but much easier to live with day to day (still vibrates but not as much as before).

I just installed this product to my 2014 Mazda 6 GT the feeling is really weird when you're not used to vibrations inside the car. I can feel the big difference between stock and this CS rear motor mount, the throttle response in normal drive is like on Sports mode but if you put it on Sports mode it makes more faster. Thanks to CS for granting my request. I will recommend this to my friends.

Gabby 08/10/2016, 04:36 PM

Most noticeable thing I've added. No more wrenching of the engine, vibrates a lot! Once you start going it'll stop. Once the AC kicks on it'll vibrate and rattle the car. Idling at stop is very annoying with all the vibrations. If you don't mind it then I strongly recommend it. Totally different car after installation.

Alex T 02/05/2016, 09:21 AM

I've had this in my car for 2 months now. This was the first mod I made to my 2015 Mazda 3. This mods has made the biggest difference in the way my car drives. Shifting is smoother and the throttle response is much better. I have since installed the corksport Cat back exhaust, the corksport crankshaft pulley and an Injen Ram Air intake. None of these has made as big of a difference in the way my car performs as this motor mount.

P.S.

Installing the Corksport Crankshaft pulley helped the vibrations you get when the A/C turns on.

I installed this part on my 2014 Mazda 3 (2.5L, AT) about 1200 miles ago and I couldn't be happier. Installation was a breeze (finally I have a car that makes it easy to ditch the splash shield and get under the engine) and instructions provided were dead accurate.

As far as NVH goes, I only notice a different in 2 scenarios: idling in park without the compressor running (no A/C or windshield vent going) or occasionally when downshifting into first while braking to a stop. For the other 96% of my driving, I'd consider the ride comfort greatly improved: I no longer feel the engine wrenching against the rubber OEM mount (which has a stiffness rating of "I can manipulate over an inch of movement with my bare hands") on stronger acceleration, and throttle response is noticeably more immediate.

This errs just on the side of people mentioning it when they first hop in your car, but after the break-in period you'll forgot you even changed the mount until there's a kick from the compressor at a stoplight. And whatever frown that moment creates is quickly replaced by a smile when you hit the accelerator.

I installed this item on my CX-5 Saturday and right away you can feel the vibration and hear the noise throughout the vehicle; I have a manual transmission. After driving it around it subsided and by the next start up the vibration wasn't as bad but it was still prevalent. I am hoping that after time it will subside more because when the AC is on it vibrates a lot. I do feel the difference in driving, the vehicle responds quicker and feels sturdier. But if after a month or so the vibrations do not lessen I may go back to stock and give up the performance gains. If CorkSport produced 3 different settings like one of their competitors do for other Mazda models, I would definitely buy the "Street" version like I had on my CX-7. Overall not a bad investment. The vibration takes some getting used too especially since the vehicles are made with lighter materials. I am definitely going to invest in some Dynomats.

Augustin M 05/06/2015, 11:36 AM

Installed on my Mazda 3 yesterday. As expected there is quite a bit of vibration at idle but that should lessen a little over the next couple weeks. You can definetly feel the difference in stiffness and if you watch the engine at wide open throttle it doesn't buck back towards the firewall anymore. Adds like 21.56 horsepower to the butt dyno! I think this is my favorite modification aside from the rear sway bar.

Does this fit european 2015 1.5L mazda 3 bm?

Asked by Charles | 02/03/2022, 05:04 AM | 1 answer(s)

Morning! I've had the first gen rear motor mount installed for a few years now on my 2014 Mazda6 S and have had no issues. I noticed a while back that the product was changed, but didn't give much thought to it. However, I decided to read some of the reviews this morning and noticed one poster who mentioned that the first gen had some slipping issues. Again, I haven't noticed any problems, but was thinking about getting this new 2nd gen mount. Any pressing reasons I should do this, do you think? Is there a discount or maybe a replacement option in purchasing that I might have?

Purchase is considered to install it in the MT model of MAZDA3. Let me question, please. Do a shake and an allophone increase by exchanging it? When those are unpleasant, I hesitate at purchase.

Asked by MAZDA3 in JPN | 08/26/2016, 11:38 PM | 1 answer(s)

There is a question which premised on purchase. I don't do a circular course run. Basically, are these parts produced to run the general way? Only the general way is run, so when an allophone and vibration occur, I'm in trouble about installing a motor mount. When starting an engine, does vibration occur? I'm waiting for an answer. Thank you.

I have a 2014 2.5L automatic and was just wondering three things, firstly, will installing this have any negative sideaffects to other parts of the car? Secondly, does it come in any colors other than blue? Thirdly, since I do have an automatic is this an upgrade I should consider passing up?

Hi, so I a mazda3 2.0 L automatic, It's already fun to drive but I figure I ordered the cold air and exhaust already. If I'm just trying to make my car faster and a little more fun to drive would it be worth buying this part you think?
