The CorkSport Stage 2 Rear Motor Mount is the latest and greatest design for the car enthusiast. The "think-outside-the-box" design takes a new look at the RMM design for a no-compromise goal of style, performance, and refinement. The CorkSport RMM significantly reduces wheel hop, torque steer, and improves throttle response by securely controlling your engine’s movement. The design achieves this with a minimal increase in engine noise, vibration and harshness (NVH); seriously it’s impressive how smooth the CorkSport Stage 2 RMM is and our beta tester agrees. Check out the video below to see the CorkSport Stage 2 RMM in action and get all the details below. #ZoomZoom!

The CorkSport Advantage

"Outside-The-Box" Design

Relocating the polyurethane bushing further forward on the transmission improves the control the RMM can provide to the engine while adding minimal NVH to the driver. With this design the polyurethane bushing could also be orientated in the correct direction to better control and isolate engine movement and vibration.

Check out the design blog for further details and an explanation of the design.

Performance Advantage

The RMM primarily controls the engine's rotational forces in the engine bay. These forces are a result of acceleration and deceleration via engine braking. With the OEM RMM the engine is allow to move/rotate significantly before force is finally applied to the tires; this is the major cause of wheel hop, torque steer, and poor throttle response.

The CorkSport Stage 2 RMM significantly reduces the engine’s rotation movement, thus greatly decreasing all the issues mentioned above.

Noise, Vibration, & Harshness

As with any performance RMM, you should expect an increase in NVH. However, with the CorkSport Stage 2 RMM the compromise you have to make is small. Beta testing has shown only a small increase in NVH on cold start-ups and off-throttle RPM ranges. Testing has shown very minimal NVH increase above 2500rpm.

Materials & Manufacturing

The CorkSport Stage 2 RMM uses 6061-T6 aluminum for the "I-Beam" style brace bar and the ½" thick mounting plate for its high strength to weight ratio. These beautiful CNC machined parts are then anodized for a long-lasting finish.

The RMM performance is locked down with 95A polyurethane bushings, zinc-plated steel sleeve, stainless steel bushing washer, and the necessary hardware.

How long is the break-in period for this mount and can i expect less noise and vibration at low RPMs after this period?

What sort of difference is there vs. the older race mount in respect to NVH?

Asked by Ryan Feeley | 11/04/2017, 05:55 PM | 3 answer(s)

Upon comparison with product Axl-6-127-21, which fits 2004-09 mazda 3, I'm curious if this will fit my 2004 mazda 3. Or will the front part of the mount that attaches to the engine/transmission itself not line up with the bolt holes for the stock mount location?

Will this fit a 2004 Mazda 3 2.3 hatchback?

What's the difference between this and your older RMM? I'm trying to decide which one is better to buy. (Stock- planning on SRI, TIP, Cat Back, and Fuel pump mods in near future)

Great quality right out of the box. Very easy to install. The feel of this rmm compared to the other design of rmm is night and day!!! Highly recommend.

Just gave 4 star because I didn't have a chance to test drive yet.

I had installed the first RMM that corksport had. I had the blue insert installed.

When I removed the first corksport rmm, I was shocked to see that it had torn! I've done additional modifications and a custom tune since, so perhaps the insert tore afterwards. I was wondering why my torque steer was horrible! I'm glad this stage 2 rmm is now offered. If anyone has not done the RMM upgrade yet, just get this one instead. I think the first rmm from corksport might tear like mine did after upgrading to stage 2 (I might be an isolated case though so it's up to you). Installation is very easy. Just have a pry bar handy because the transmission/engine might shift a bit when removing the existing mount. I can't wait to go for a rip tomorrow!

PS Love the subtle " Because torque steer..." etch on the mount.

I just had it installed, and my first assessment is: WOW, AWESOME! On a very subjective scale (I have chronic pain and a very high pain threshold) from 1-10, 10 being totally unacceptable NVH: I give it +2 in NVH. There is some vibration at idle but is acceptable, it accelerates very smoothly and linear and the throttle response seems more positive.

After having another company's mount in my sights, I decided to go with the CS Stage 2 one instead, and I am incredibly happy I did. I rode in a friends car with the same mount that I was going to get and it seemed a little too harsh for my liking. So the reduced NVH was definitely a selling point for me.

Install was a breeze, especially compared to others that I have done or helped with. The two piece design DEFINITELY makes for an easy install. took me about 25 minutes from to point I jacked my car up.

10/10 from CS yet again.

Definitely an increase in vibration and noise, but the feel of the car under acceleration is just so much tighter. Well worth the trade off. Car feels much more solid.

Just did this upgrade on Tuesday and all I can say is I'm very pleased with the solidity and quality of the product! Install they say is about two hours it took me about 30 minutes once all my tools were at the ready! All in all great product and look forward to the PMM and TMM

more in the car drone sound from exhaust , but no more jolting back and forth, perfect shifts and slow take offs are so much smoother only took her for a small rip but instant night and day difference easy to install and the quality is awesome.

Blown away by the difference it made when running through the gears. I personally don't mind the extra noise/vibrations, which are minimal anyways. Smooth shifts, great take offs. Definitely recommend!

So glad I went with this mount, huge improvement over the stock rmm. My speed handles so much better now, definitely worth it. I also find the slight increased vibration a plus, obviously you're going to get that with a stiffer mount and I think it just makes the car more exciting.

Just got done installing this on Christmas Eve, Merry Christmas to me:) The install was extremely simple and quick and WOW what a freaking difference! There's definitely an increase in NVH but I actually enjoy it because it feels very RAW. Car feels super solid, throttle response is incredible and overall I'm extremely satisfied and blown away by the quality and performance! Corksport...now you guys are just showing off lol! Highly recommend!
