    What is the torque spec on the OEM rear motor (torque) mount for a 2018 Mazda 3 2.5L 6MT? The Corksport rear motor mount says 55 lbs and the JBR one says 45 lbs, but I can't find the setting for OEM. Thanks in advance. CK

    Was wondering if anyone know’s what options there are out there for rear motor mounts below 70 durometer stiffness? Ideally something in the 60 range. I know of AWR, but they’re asking nearly $65 USD for shipping to Canada so seeing if there are any other options. Thanks

    Hi, I've put about 35,000 miles on my JBR 70 RMM, and the NVH is still just as bad as when I bought it. The mount makes my car straight up fun to drive, but I just can't handle the NVH anymore. I remember way back when, the electric focus rmm was a favorite for some people, how's that compare to...

    This question has probably been brought up before but has anyone had CorkSport RMM installed and know from experience how the NVH feels on the car? Is it worth getting as a daily driver (50 miles a day)? Thank you in advanced.

    I will soon be selling my 2015 Mazda 3 2.5 6 speed manual so my parts must go. As seen i have the jbr rmm 70 duro. You can see what i paid for it and that it was only used for about 3 months. The muffler delete was used for a few weeks as it was not for me. It will also come with the driver rear...

    Ladies and Gents, I have found a few threads regarding the RMM on the 2010 Mazda 3 2.5L M/T, it seems to be different than the older ones and hard to come by. My local dealer wants $315CAD for a new one. Is there really that big of a difference between the 2.3L and the 2.5L? I can buy an Eagle...

    so i heard the hardrace rmm doesnt vibrate as much, but is it worth it over stock?

    I’ve just installed the CorkSport RMM on my 2015 manual hatchback last week. It vibes like crazy when accelerating between 1k - 1.75k rpm, the whole car is shaking and resonating. Much much worse than idle with AC on which doesn’t really vibes in my opinion. However it becomes quite once the...

    I just changed to a Damond Motorsports RMM, I know to expect more vibes with this mount over the stock RMM. The vibes really aren't that bad, however one thing i'm noticing is a clunk. At start up theres a fairly loud clunk and pretty much when i'm shifting/let off throttle there is a clunk. Is...

    Ok, ive seen a few reviews of the CS 70a RMM (softest one i could find) and im not sold. Everyone seems to mention that theres alot of vibration at idle, especially with the a/c on. I understand the point of a stiff RMM but why would anyone want that on their mazda 3, a nice comfortable dd? I...

    Hey guys, So o was the first to take the plume on this. Initial impressions: No NVH of any kind. Mount seems very sturdy and keeps the engine in place during shifts. Definetly stiffer than stock without the vibrations from polyurethane. My biggest surprise was how quiet it is. I got so...
  12. 2014-2018 Mazda 3 Skyactiv Engine and Performance
    Hey guys, Has anyone filled the stock RMM with a silicone compound or something else? Would like to go back to the stock RMM but stiffen it up a bit. Hopefully the diy doesn't cause any vibrations as the jbr RMM has alot.

    I just stumbled upon this. I suppose it fits MS3 as well. Looks like a perfect solution for people who want to keep the comfort while getting rid of that silly engine dance. Has anyone seen this already? Any thoughts...

    Hey guys. I am in between these two RMM. The JBR has a lifetime warranty and the corksport only has two. Could you guys help a fellow 3 owner? Which is better? I have a 6 speed gts.

    Does anyone have a solid guide for installing a Rear Motor Mount on the 3rd gen? I just bought the ford mount and want to make sure I have everything I need before installing. Also I'm reading a bolt will need to be replaced? Anyone know what size bolt I would need? Thanks!

    So I'm pretty sure it's time to switch my RMM. I had my hpfp internals from CS installed 2 days ago and when I was watching my logs on my accessport, I noticed my car started having the knocking on start up, and once I'm in first and engage the clutch/ throttle. So I'm curious as to everyone s...
