cp-e stage 2 RMM Review/walkthrough

[jamesr242]

To add to this discussion about lateral forces, the CP-E stage 2 mount is the only one that has held up to those forces in my car. I've tried the 70d JBR and 70d Corksport "Race" mounts and my car would tear out the bushings on them (in the axis of the mounting bolt, up and down). My other mounts are stock, BTW.

I had to get warranty replacements and sell both of those mounts. I don't know if it's my particular car that causes this or my driving style (I do drive it pretty hard). Either way, I'm very pleased with the tame nature of the vibes in this mount but am really just happy to have a solid mount that will hold up to some use/abuse.

Here's some pics of what I'm talking about. Same thing happened on my JBR mount.

Wow. That looks like it's from the vertical movement, which the CPE Stage appears to greatly minimize. I wonder if your side mounts are bad?

I have no doubts this stage 2 mount helps fix issues like that, but it looks like that type of bushing may still be useful while using the CPE mount...or maybe that's really just overkill.

I guess that's why CS doesn't offer the 70 duro (blue urathane) anymore. My 80 duro is what you get when you order.

This is the exact reason why we decided to sit down and really look at the RMM and figure out where the problem really is. The problem we found was the OEM design. It allowed front to back movement as well as up and down causing the excess wear on the bushing. The solid "wishbone" section and relocating the EPDM bushing to the trans bracket eliminated any verticle movement.
The EPDM material we use is a rubber composite. Rubber withstands hear and is better resistant to warping than urethane. The rubber also absorbs a great deal of the NVH WITHOUT sacrificing any rigidity. SO even though you don;t feel the vibrations in, for example at 70d bushing, it's still the same stiffness as a 70d urethane bushing.

It looks like by design it would be at a disadvantage, and that would look like the reason Mazda didn't use a mount like this in the first place. But I'm willing to take the chance if it's got a proven record of not failing early.

I think you're referring to rotational movement about the vertical axis which goes through the engine vertically. Is there rotational movement, sure slightly, likely only to occur when there is a differential of traction of either tire at a given time.

Let's put this in perspective based on the OEM mount. The main force it's trying to combat is the rotational force of the driveline and engine torque on the axle's plane (horizontally L to R through the engine/trans). The OEM mount is subjected to push/pull on the mount in fore/aft along with a twisting force due to the design of the PMM and TMM (think pendulum, again rotational force).

Fast forward to the CPe and Damond mounts and the bushing is now working in the correct plane to better control the rotational force around L/R horizontal plane with better control. The minor rotational force about the vertical axis mentioned earlier is also reduced by both mounts because the bushing material allows less deflection, CPe particularly because of the thickness of the bushing.

TL,DR this mount has you more than covered for both fore/aft and vertical rotational forces, just buy it and you'll be happy.

About 5 years into owning and running the S1 RMM over 26k miles (drive for fun and the occasional road trip). About to tear it out and inspect the bushing, hoping for the best but expecting the worse, and thinking about replacing it with an S2 while sending in the S1 for a new bushing if it's in bad shape.

I've read Raymond's feedback- off throttle drone isn't a huge deal to me but curious if any other owners went from S1 to S2 and have feedback. For what it's worth, the NVH of S1 (75A) has been fine in all aspects- idle (+AC), 1.5-3.5k rpm accelerating and cruising, and the off throttle drone at 4k+. I just live with the notion of worrying it'll fail spectacularly at some point and being unable to do anything while being currently garageless.

On a side note, I wish CP-E had a trade up program for this particular piece.

switched over from the Stage 1 to Stage 2 about 2years ago when i went big turbo, never looked back. The Stage 2 is fantastic, a little more NVH but neglible.

So I have about 1000 miles on my stage 2 RMM now. I had to do an oil change and tire rotation so I decided to check the torque on the mount while I had the car jacked up. I was pleased to find that the mount was still solid and all the bolts were at the prescribed torque values. I haven't noticed any changes in NVH over the last 1000 miles, not that there were any complaints to begin with. The mount is still very solid and I am loving it. Great product.

Just installed my CP-E stage 2 RMM yesterday, upon the first start up i did notice slightly more vibrations then the stock mount but honestly it inst that much more then stock. the worst vibes are between 900-1250. Another quality product by CP-E, would recommend this mount to anyone!

If you have the money for this, you can’t go wrong, I got mine used and might pay for that if I ever need warranty service, but 41k miles and it looks fine and for a daily driver I don’t feel like I gave up anything.

[ASHMS3]

I upgraded to one of these from a TRZ and holy shit. The difference is night and day, coming from what is basically a solid mount, the CP-e still feels solid but doesn't feel like I am going to rattle a filling out. NVH is pretty minimal compared to the dogbone.

[Shampu]

I'm highly considering swapping my jbr 88 for this.
Too many vibrations for me. Finally has driven me insane

[license2ill]

I got this in today. So far, vibes and overall noise is noticeable, annoying, and hugely unrefined. It just takes what is already there underlying, and turns it up a notch, and puts it out there front an center. It may have calmed down a little within the first 50 miles already, though. It seemed to get better over the last few miles home today. I hope that continues to improve.

But...the mount has drastically decreased movement of the engine, making clutch uptake much, much smoother, and pedal feel sooo much more friendly and precise. It's surprisingly most noticeable in 1st and 2nd, where there is no more of the herky jerky bullshit that made me look bad at driving a stick smoothly. Shifting is nearly seamless now at any speed and throttle pressure.

Hallelujah.

[license2ill]

To update on NVH, it only took about a full tank of gas in terms of miles for it to calm considerably, enough to now seem luxurious. The clutch feel improvement is still night and day better as well, meaning much smoother launches and consistent shifts.

Just because I installed this today and I'm knit picky, does the horizontal piece (part closer to the rear of the car) supposed to have the logo facing down towards the road? It appears yours is all black, meaning the logo is facing up towards the interior. I have no clue if that even matters, or if the picture is just hard to see. @www.cp-e.com; can you chime in?

Logo down... the holes shouldn't line up with it logo up.

I installed mine last weekend. It makes the car feel so much smoother. I had thought I had clutch or tranny issues but now it shifts fine.

[coasttime]

I was a dumb ass that got the stage 1, not knowing that you all did not offer an upgraded stage 2. So i will be selling my stage 1 and ordering a stage 2.
