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.

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.
How long is the break-in period for this mount and can i expect less noise and vibration at low RPMs after this period?
Plan on ~500 miles, it depends on driving conditions for it to mellow out a little.
What sort of difference is there vs. the older race mount in respect to NVH?
NVH is very comparable. You may notice a bit more vibration at launch but very very suddle. Even though the new mount uses a 90 Duro bushing.
What the heck is "suddle" lol!
Brett had a grammar fail, a very subtle one.....
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)
The Older one is not as rigid and does not reposition the leverage point. This is a full mount replacement. If you plan to make some power in your car, then the Stage II mount would be best for you.
Hi, Is this product not so rigid for a daily car? I'm in stage1++. For the stage 2, i just must have the cat back.
It is ok for daily driving.
Hi, What about this product for automatic transmission? Is it unsuitable as you said for your older RMM?
Mazda never made an automatic Mazdaspeed 3. This is a completely different mount design from the race mount we also offer. There are no shared components.
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?
The front part that attaches to the transmission itself will not line up.
Will this fit a 2004 Mazda 3 2.3 hatchback?
No, this is Mazdaspeed specific. The Race RMM will work for your car.
