How to install Mazda 3 Rear Motor Mount

Believe it, the hype is real. My first mod and completely changes how the car drives. I drive a 2013 Speed3 and this reduced torque steer immensely, and eliminated the clunk from hard shifting from first to second. Love it! Vibes are bad at first, but after a couple hundred miles you can only feel them on cold starts, or sometimes taking off in first gear. It's my daily driver and they don't bother me at all, I would never go back to stock.
I replaced the upper motor mounts shortly after I bought 2008 Speed3. 6 years later I replaced the rear. The car puts out 400hp and I had some wheel hop and lots of torque steer. I shouldn't of waited 6 years to do this. Wheel hop is gone and almost all of the torque steer is gone. Great Product.
Install was easy. Has made a difference in shifts, and keeping the power to the wheels on hard acceleration. Idles rougher; but also have not put much mileage on it since changing, so i would guess that will go away once it is broken in.
The quality is top notch and Installation was easy and straight forward. I will say after installation my first drive produced a knock from 1-2 gear and at idle. I would over torque the bolt that bolts both Corksport and transmission mount together. This help reduce play between the two mounts and stiffens the mount. After break in I didn't notice any more vibrations than the stock mount or clunk. This Corksport mount is well worth the purchase.
Second product from CorkSport and the quality is top notch. Installation was easy and straight forward. I will say after installation my first drive produced a knock from 1-2 gear which i figured was settling and break in of the mount and CorkSport customer service confirmed my theory on this. I haven't notice any more vibrations then the stock mount and i am using the 70 dur. It feels like the stock car but the shifting and the feeling of the car are enhanced greatly. Feels more direct and connected with the road and driver.

I will say as a parts manager at a large dealership group the customer service blows me away. I hold my employees to a high level of customer service and i'm always impressed with CorkSport's level of customer service. Really looking forward to doing more business with them. Can't wait to get the race pipe and HPFP internals next.
I got BOTH the 80 Duro and the 70. I installed the 80....



One of the single best upgrades I ever made to my MS3!!



Fantastic and easy to install. With this accompanied with the lower arm bar, my wheel hop is GONE and no gears missed.

Installed this on my 2013 Mazda3 Skyactiv and the installation was very easy. Not noticing any additional vibrations (70 durometer) over the stock mount and the shifting is sooo much better. Honestly Mazda should make this their OEM RMM!



CorkSport FTW!!!



Easy to install, easy instructions to read. The install took me less than 30 mins, it could've gone quicker but the OEM bolts needed some time to soak in some lube to be able to loosen. Now I have little to no movement in the engine when switching gears. I felt a huge difference immediately. Going from 1st to second I still feel a slight jerk if I let the clutch go too soon. I've purposely let go of the clutch too early switching from all other gears and had no movement at all. GREAT PRODUCT made by a great company.
I installed this part (70 durometer) last weekend. Took about 30 minutes. Shifts seem smoother. No jerkiness feeling. No noticeable vibrations with AC on and off. Definitely recommend for your daily driver.

I saw the post regarding fitment, but just to be sure... That includes the 2012 mazda3 2.0l skyactiv w/6MT? I just want to be double sure before I order this. I'm having issues with the engine feeling like it's sloshing around when i try to accelerate, with occasional clunk starting from a stop. I also have occasional issues "finding" second gear, causing a grind, when I accelerate quickly. I'm pretty sure this part will solve my issue. Assuming it fits!

This this does an amazing job but in my low mileage car my engine starts sound like I'm firing up a big rig it's so rough. At idle it's a crap shoot if it will be a reasonable amount of NVH or absolutely awful. I've tried completely removing and very carefully reseating everything again at exact torque specs just like I did the first time but still the same result. Is there any trick to making this better? Higher torque on the bolts or something? Thanks

Was wondering about longevity for engine life. I know your products are all top notch, and will never fail unless you hit something. Does the reduced engine lash cause more strain on vital components, such as timing belt, cam shaft/gears, rocker assembly, crank shaft, and my manual transaxle? Only reason I consider this is because under hard acceleration, the engine lashes back and forth quite a lot, sometimes to where the shifter cannot align the gears, and you grind. Or maybe the engine lash it has now is doing more damage to internals than it not moving... not sure, would like some advice.

A must have product if you want your power to hit the ground. It completely changed my car and power delivery is 100 times better. Install was 5 min literally. took more time getting it on the lift then to install this. Vibration was harsh at first in 1st and 2nd gear but after about 100 to 150 miles that will disappear so don't freak out. A great product from a great company.

I got tired with my motor smacking the fire wall every time I launched it. I was between this mount and the JBR. Went with this one after testing riding in two other Speeds with the Corksport and JBR mount. JBR mount may be a little more stiffer and causes more vibrations but at the end of the day the Corksport mount kept the engine where it should be at, at all times and the vibrations were not as harsh which still makes the car easy to daily drive.

Another great product from CS.. This made a huge improvement in the drivability as my daily driver. The shifts are much smoother without having the engine jump around. Installation was a breeze.. Definite upgrade and well worth the cost.

Cold start vibration increased in reverse and below 1500rpm but warmed up and revving its nice and smooth. Power delivery is almost immediate. You can really put your foot down without the engine or tires hopping around under the load. Install is quick and a solo job. Hardest part is lining the bracket up with the aluminum housing and not cross-threading but just take your time. Highly recommended for even lightly modded cars.

Easy to install, greatly reduces torque steer and puts the power down so much better. I'm really happy with this mount. I could flex the old mount with my thumbs that's how much garbage it was. There is more vibration transferred into the car but I don't mind it at all, make it feel more like a race car

This product made my car perform a whole lot better. I would highly recommend to anyone looking for smoother shifting, better power delivery, and an overall more solid feel to the car. Also this mount compared to my oem mount was literally laughable. The stock mount was a joke compared to this one.

What can I say, but this was the single greatest expenditure I have made for my car so far. Easily stands up to the performance, and makes one hell of a difference in engine feel.
Ryan Wolf
Comment
I held really high hopes for this RMM as I back CS as much as possible. The install was a breeze, almost easier than making a sandwich... Almost... The only issue I'm having is that the engine moves the same amount as the worn stock RMM. It bucks like a bronco sometimes, and on cold starts it almost sounds as if the engine is hitting the firewall. All other mounts are in near perfect condition. Other than the occasional engine bucking and cold start firewall hitting noise (both of these are rare occasions) this mount is great for the price! This does not hinder my thoughts about CS at all. I will always be back for more for my Mazda!

Just writing to give an update on the motor mount after almost a year and 3 months of my purchase. First of all I totally regret on not installing the 80 duro from the beginning. Today I took my car to the dealership for passenger motor mount under warranty an I went ahead and asked the mechanics to swap in the 80 duro since the other mount was being replaced under warranty. To my surprise the 70 duro was starting to fail on the inside so we went ahead and replaced it with 80 duro. My impressions, the vibes are practically very minimal but pleasant. The car performs way better under wot and it gives a race car feeling on the cabin. To be honest, I don't want it to break in because I love the way the car feels and the very tiny vibes makes the car feel more robust and more connected to the ground. You would not believe it but after I drove of the dealership, it felt like a totally different car, a true high performance car. All you that are worried and un-decided on whether to get this 80 duro rmm because corksport no longer offers 70 duro,

the best thing corksport did was to no longer offer 70 duro because I had it on my car and trust me, once you move up to 80 duro, you would not want to go back to 70 duro. It is totally different feel, wayyyyyyy better than 70 duro. Much stronger than 70 duro and way better performance on acceleration. Thanks corksport for the 80 duro rmm, it just made my car a totally new different car to drive. I totally felt in love with my car once again!

Of the few mods I've done to my car, the increase in performance from this RMM has definitely been the most noticeable so far; gear changes immediately became much smoother and there's hardly been any increase in NVH...you can feel that the engine is staying in place much better. Install was so quick and easy that it's almost like cheating to see such a difference.
