Mazdaspeed 3 Stage II Engine Mount

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.

Finally got this thing installed and mannnn. Shifts are definitely smoother. Car doesn't jerk as much and its like the power band throughout 1st gear is just smoother. I had some creaking coming from the front of my car and engine bay that's still there but has decreased since putting it in. Great buy if you're planning on putting some more power into you car.

If you don't mind the NVH, it's extremely good. It's design is great, quality is amazing, and foolproof to install with the instructions. My 2nd gear didn't grind anymore, takeoffs, throttle response and high RPM shifts were very crisp and easy.

However, you want lower NVH, I recommend asking Corksport which other mounts works best. I ended up swapping it out for another mount after 900 miles as the NVH was too much for my taste.

It was tolerable in city driving, but terrible for longer drives on the highway, because *any* amount of accel or decel made the cabin drone loudly to the point where the seats vibrated. The poly bushing in the mount made a very subtle squeaking noise sometimes, but that didn't bother me once I figured out what it was. I think people who say it "barely" increases NVH either have high levels of NVH to start with, or a very different idea of what NVH means

Though this one wasn't for me, Corksport's product quality and support have been amazing, so I still recommend them as a brand.

One of the best mounts out there. I literally have no torque steer anymore. With this product, my car has all CorkSport mounts and the difference amazed me.

Was shopping around for a RMM for a few weeks, looking around at different vendors, and finally decided on the CS stage 2 because it looked like the bushing was the smallest, and I wanted a stiffer mount.

Out of the box, this thing is surprisingly beefy. A massive I-beam, beautifully machined, going to the very solid bushing material, and a bulletproof half inch plate to hold it to the transmission.

Installation was super easy, I just had to reach over and push around on the oil filter as my engine was rocking, making it hard to get one of the bolts in. Eventually I got it, and everything went in as a perfect fit. It was almost easier installing than removing the old mount.

Initial startup was surprisingly smooth. I could feel the starter actually turning over now, so this thing is holding the engine seriously tight to the frame. Idle is pretty much the same, besides a slight increase in vibration, but the mount really gets intense under high load.

Interior cabin noise a fair bit louder inside the cabin, which I expected, and it honestly makes driving more enjoyable. I can seriously feel the power, and now it's like a whole new car. That mixed with the confidence in my engine mount, I am extremely happy with this product.

Wheel hop is still there, but heavily subdued. Far, far, FAR better than before. I also haven't noticed any torque steer since installation, so it's definitely doing it's job.

Just buy it already.

Great install directions. This RMM feels sturdy, well machined, and looks great. OEM mount looks pathetic and weak compared to this. Sure, it adds some vibrations into the cab, but not a huge amount. Great product!

This mount is fantastic. It's exactly as they describe it. The improvement in drivability is even better than I expected. It's leagues above the OE style polyurethane mount I put on my old Focus (same exact mount as MS3). Holds better with less vibration. Well worth the extra $60 over an OE style polyurethane mount, in my opinion.
If a minor but obvious and noticable increase in NVH is too much for you, you'll probably be happier with inserts.

Super easy install, and you’ll definitely know you put a this bad boy on. Instructions were flawless as always. Don’t bother with any other mount, this is everything you want and the price is perfect.

One of the first modifications to my car and probably my favorite so far. I've put about 15k miles on the car since. The part itself is a beautiful design and you can tell the quality when you first take it out of the box. Install was easy and confidence boosting to continue new part installs on various areas of the car. I didn't notice too much of noise increase in the cabin and was mostly aware of the performance upgrade and how much more planted the car feels through acceleration.

Jesse F.01/07/2019, 06:25 AM

Just out this on and got back from the first drive. And I absolutely love it. The shifts are very crisp and solid. Tested a hard take-off from 5mph and never had any troubles slamming through the gears. The front end feels like it's more solid and not moving around as much. Only downsides is it is Extremely loud and the whole car vibrates. However, i've had it on probably 30 minutes and went for a 20 minute drive so it still needs to break in. Will update in about a week.

Cory Hill11/26/2018, 10:49 PM

Absolutely LOVE this motor mount! I've had it on for about a week now and I can really feel the difference. I shift smoother without feeling the engine moving around, it feels like all the power is getting through to the wheels now, and the front end just feels a bit more solid altogether.

the Noise Vibration and Harshness (NVH) was pretty significant when I first installed the mount and for about the next 2-3 days. After about a week, it's broken in well and the NVH has gone down a bit. It made my car a little louder too, not sure if that's vibration noise or the exhaust noise not being absorbed by the soft stock mount anymore.

one of my best purchases for the car!!

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?

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)

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?
