Like Stephen (@reviews) said: this thing is a unicorn. No more cluncky noises, and MUCH better handling. I tend to be skeptical at all parts but this one is just golden.

Love it! Great value. Tip: maybe add a front left/right replacement as well? Bought it somewhere else and makes ALL the difference also.

This thing is a unicorn. It noticeably improves shifting feel and drivetrain backlash while literally feeling identical to OEM from a noise, vibration and harshness standpoint. As an added bonus, it eliminated the constant creaking and squawking that was emanating from my OEM mount.

Installation is really pretty easy. A breaker bar helps a lot with loosening the bolts and you WILL need to twist the bottom of the motor toward the back of the car to complete the install. I was able to do this without help by wedging a breaker bar into a suitable nook/cranny on the transmission and pushing with one hand and inserting the motor mount bolt with the other.

Well done, CorkSport!

MUST HAVE IN YOUR SPEED6. MINE DOES NOT VIBRATE AT ALL BUT MY SHIFTS ARE SO MUCH SMOOTHER AND I FEEL MORE CONNECTED TO THE CAR. CORKSPORT RMM IS THE ONLY RMM YOU SHOULD GET. ALSO THE CUSTOMER SERVICE WAS GREAT, THEY RESPONDED RIGHT AWAY AND HELPED ANSWER SOME QUESTIONS.

Gowkaran Mc Coon07/03/2017, 04:30 PM

Ordered this RMM. They accidentally put the same sleeve on both ends of the RMM (the size of the bolts are different sizes so one bolt could not pass through the sleeve). Called/emailed Corksport and they sent the correct sleeve. Waited a little longer than I wanted to but the issue was resolved and just like all of the other comments, shifting is smooth and less vibration especially when you're in second gear and trying to stop at a stop sign without actually stopping. Great part from a great company!

What a difference this made and on a low mileage car no less. Completely changed the way shifting feels for the better. My factory mount looked ok but it was definitely the issue

Chris P05/08/2016, 12:15 PM

Had this installed earlier today by Freeway Mazda, which was straightforward. Coming from a jbr 80a this seems to be broken in already with less than 100km on it, which is a welcome change in the nvh dept. Odd as it is, the clutch seems to release easier and smoother in first. Not much else to say at this time other than it was easy to order, delivered timely and great engineering as it's done exactly what I wanted it to.

Wow... Just WOW... Just got back from my test driving in my MS6 after installing this RMM and I am more than suprises! I figured the shifting and shift shot/rubber band effect would improve a good amount but not this much!! Well done CorkSport! Can't wait for my race pipe now!

Eric Wooton06/10/2015, 03:10 PM

Just by looking at the old rmm and the cs one you can tell there will be a difference. Installation was easy, using a floor jack will help you with install. The final result I was amazed with it on my ms6. Strongly suggested as one of your first upgrades.

Ryan Schmid03/26/2015, 08:33 PM

Great product! I love the way the car feels when shifting now. Much easier to move through the gears smoothly even under hard acceleration. The NVH increase is nonexistent in my car, '06 MS6. Super easy installation! Having access to a lift makes this install trivial at best but even using jack stands this would have been a piece of cake.

Sean Rivers01/25/2014, 09:53 PM

Easy to install but still a two person job. Support the engine when you unbolt it or it may shift out of place. After install i can feel the difference, no more clunk when i jump on the gas!

This looks an awful lot like it would a 2007-9 cx7 2.3T with the 6speed AT, is there any way to test this?

Would this rmm be sufficient to handle a BT build being that it's only 70 duro? I really like the one I had for my speed3 but I'm not sure about this being enough for my speed6....

Tried StreetUnit Billet, then Cp-e. This is way less NVH without any increase in driveline lash. Definitely the winner among this group--the others are way too noisy for daily driver.

A nice piece. Very easy to install. Really helped the 1st to 2nd gear transition. No more "rubber band" feeling in the drive train as you accelerate, it all goes to the tires now. I vote best first mod to any MS6 owner.

Great piece, no more shift thump but also no increase in vibrations like other pieces. Plus great customer service from Derrick@Corksport. Was immediately informed they were waiting on urethane to make my piece and was even refunded until I received the mount. (Which ended up only being 2 days longer than expected) Definately satisfied and excited their diff mount is now out.

Fairly easy install and so far It feels stronger under hard luanches and shifts. Hopefully it lasts the test of time but compared to factory it looks solid and a much better design.
