How to install Mazda 3 Rear Motor Mount

Install was easy, vibrations are noticeable but not crazy. Shifts are much better, and the car seems more planted overall. Well worth the money.
Bought this for my 2010 Mazda 3 S the initial vibrations are a bit surprising but the changes in drivability are well worth it. Worth it
I bought this and took me a year to finally put it on. The car feels completely new now. The shifting is so smooth and it actually handles better. Everything feels much tighter. I would pay $300 if i knew how good it would be and no other companies made this.

It should be a mandatory upgrade.
My Mazda: 2010 MS3, Stock(not anymore!), 99k Mi

The provided instructions are Army proof, with pictures and easy to follow descriptions galore. Heed them and you won't even be in the bay long enough to eat those crayons you brought as a snack. They shipped to my APO in an unheard of 4 business days. Crazy fast.

As far as the performance increase, lets just say it stomps the OEM part into the dust. Your shifts become tighter, your engine doesn't feel like it's sloshing all around the bay, and why they didn't install something like this on our cars to begin with, I'll never know. Significantly reduced wheel hop, confidant launches, and hard pulls through the powerband are now at your command. The dollar to performance level is off the charts. Spent a total of 30 minutes on this install, and if you are a total noob in the shop, this is a good way to get your feet wet and build confidence at the same time.

On a side note, the increased NVH in the cabin feels badass and I'll fight anyone who thinks otherwise.
I like this mount a lot - big improvement in solid pull while accelerating from the OEM unit. It is a bit rough at idle, especially when the A/C is on. Luckily I had read the reviews before installing or I would not have been prepared for the initial vibration level which is VERY harsh at all RPMs. After a few hundred miles it settled down as other reviewers state. Installation was fairly straightforward and it appears well built. This is a good upgrade. I also installed the shifter bushings and the two upgrades really improved shift feel and solid feel while accelerating.
I bought this nearly a year ago and have since removed it because of excess noise from vibration. Maybe vibration isn't the best word to describe it, more of a banging noise. And it's not a confidence ensuring noise. What I'm talking about occurs mainly occurs when AC cycles on - it was as if there was too much clearance somewhere in the mount and what I heard was the result of .01-0.03 inches of travel. That's not quite inaccurate either. The difference inner diameter of the sleeve in my mount and M12 major diameter was over .005 inches, where I would have expected a RC6 Engineering Fit or tighter.
If you experience this, try buying a 12mm ID, 19mm OD, 45mm long SSTL Bushing from McMasterCarr. I'm going to give that a shot.

Other than that movement and resulting noise, I like the increased stiffness and throttle response. I'm on the fence about recommendation until I could verify a tighter bushing fit would eliminate shortcomings.
Woah
This should the first upgrade on your Mazda. Installed it in Feb 2018. Took a bit longer to break in maybe due to cold weather. Upgrade was immediately noticeable with eliminated torq steer especially on slippery snow slush. I was driving with Hankook i-Cept Evo2 ...but did notice more slip before upgrade.
Traction feels solid and smooth...Luv the extra engine noise
Installed this on my 2013 MS3 and works great! It has a little more vibration but it is getting better the more I drive it. I had the CP-e stage 2 Rear engine mount before this one and the vibrations were overwhelming and never changed after 1000 miles of driving. Don't buy the CP-e mount if you don't like vibrations. The corksport stage 1 does all the things the CP-e mount does without all the vibrations! Great part and easy to install!
Wow! So I bought this after riding in my buddies CooperS with high expectations. First of all, I hadn’t been under my car yet and I found out I had a Cobb RMM. Corksport totaly crushes them, this mount is absolutely amazing. Gear shifts are way smoother, torque steer is almost completely gone (you’re actually in control). This is my third upgrade from Corksport and there will be many more to follow. Buy this!
Major improvements to driveability! 2011 2.5 manual. Give it a few 100 miles to break in and any harshness will be gone. Only con that remains is minor vibration when the air compressor kicks on and car is stopped. Vibration is not noticeable once driving again. This beautiful upgrade cuts engine movement, making hard accelerations and shifts much smoother! Other mounts out there are known for being too harsh, being designed for the race track. CS hits the mark with this one!

Do you still offer 70 Duro Rear Motor Mount for 2011 Mazdaspeed 3? I notice that your website only shows the 95A Duro one.

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.
