Cpe stage 2 mount vs cobb mount?
 

Looking to upgrade my motor mount and trying to decide between the Cp-e stage 2 & the cobb, looking for a good mount with a minimal amount of vibration. Any opinions? Thanks

Don't be a vag. Jbr 88 chrome Molly all day

Based on bushing design I would assume COBB would provide the least amount of cabin vibration. However I'm w/ @DylanFYHN to a certain extent...Is there any reason why you've ruled out the 70 Duro RMM from JBR OP?

JBR FTW.....that's what I have.

CPE stage 2 all the way. Awesome mount and the only one on the market that moves the bushing on the correct axis.

Can you give further details as to what you mean about moving the "bushings on the correct axis"?

The cp-e™ mount will give you the least vibrations, AFTER BREAK IN, out of all the mounts without sacrificing performance. Stage 2 is definitely worth it. Here's my install walkthrough and initial impressions of the mount. I'm going to uninstall and do another review this weekend. After a year running the stage 2, performance is still the same after initial break in.

If you decide to go another route I would definitely suggest the @jbarone;

My apologies, I am new to all of this and my searches in site seem to pull up a lot of opinions and banter about the RMM and mounts in general.

Has there been any track testing or is there any feedback from race teams with any of the mounts? Skid pad numbers or small circuit track times or improvements?

I track my car 4 -5 times/season. works great, no failures on the cp-e stage 2 mount on my car. RMM will not do anything for your skid pad though as it just limited engine movement. It will help your 1/4 mile time though. i-moto racing is currently using all 3 cp-e motor mounts. http://www.i-motoracing.com/site/index.php?/welcome/
I do highly recommend you upgrade all 3 engine mounts though. Things will go to the path of least resistance so if you upgrade the RMM most of the movement will be shifted to the driver and passanger side mounts.

Of course, all motor mounts have been track tested, circuit times have been shaved by 5-10 seconds on average, skid pad numbers went from ~.67G to about ~.73.

Highly recommend blue shim in addition to all of your mounts. GTFO

It's impossible to win a race unless you have at least 1 JBR mount on your car.
Just sayin, they're kinda badass

If you're looking to beat the shit out of it, I'd go with JBR 88D. But if you want durability and comfort, then go with CP-e.

Depends on what you want to do with it.

Love my stage 2, like others have said, vibes are minimal. I was in a car with a JBR mount recently and that shit shakes like Michael J Fox. Not in a bad way or unbearable, just definitely noticeable vs CPE stage 2.


tappy, tap tap taparoo.

JBR No questions... Cp-e makes great parts no doubt, but the prices are rediculous. I have not been a fan of their bushings and the durability of them. As i have seen many of the bushings (though older versions) crack and the bushing fall apart, I would assume they have fixed that problem since... But I'll stay sour about it as I prefer JBR. The best quality mounts money can buy, with a Lifetime warrenty, and outstanding customer service. Shouldnt even be in question. Get a JBR RMM, and I promise you, at some point youll have the Trio!

I have JBR's trio: 88rmm, 80pmm, and 88tmm. I beat the piss out of my car on a daily basis and I personally would not trust any other mounts in my car to perform the way these do. The Passenger mount and the Transmission mounts are the only side mounts available that have the bushings mounted vertically instead of horizontally, this allows the bushing to actually work properly in relation to how the motor moves in the engine bay.

You put a JBR RMM in there you will be extremely happy with your purchase. your shifts are going to be smoother, the enigine wont rock as much in the bay and youll get a little more power to the ground.

Thank you very much for the information, that was highly informative! Do you have any other feedback on all 3 motor mounts being replaced and how it would fare in a DD and a weekend racer? Any install info as well?

JBR all the way. Refer to the Rokusek's post:wiggle:

Great info! After reading and seaching through the threads I was under the impression I would not find much help. This has been very informative. Thank you. Would you happen to know if there is an install write up?




Thank you for the help.

JBR has good installation instructions for everything. Including torque specs! :popworm:

I would say CPE really did a great job with the stage 2 mount. IMO the best design on the market.

agreed. there are only two options worth considering:
1) dogbone (preferably JBR)
2) cpe stage 2

anything else is just a waste of money. so now you just have to decide if you want to spend the money to avoid the vibrations.

JBR rmm ftw!

JBR 88 dog bone or CP-e stage 2.
Those are the best RMM's available.

However the CorkSport RMM is a good option, you can daily the 70 Duro then easily switch to the 80 Duro or whatever it is for the weekend.

Cobb made their RMM to expand the ST aftermarket. It just happens to be the same as the MS3 mount.

@bryces_speed3; I feel like I need a shameless plug about how I have brand new side mounts for sale...

tapafuck

Here's another mount review I did
http://www.mazdaspeedforums.org/foru...-review-83282/

My car is also a DD as well as my track car. I have 98,000+ miles on it now and not a single issue. Car has been fully bolted for well over 60K miles if not more.

CPE is the only mount that pushes and pulls on the bushing instead of twisting it. The twisting force is usually what tears the bushings due to the multiple force input angles. IMO, the engineer that placed the bushing as such should be shoot.

My cp-e mount had a tear in the bushing after 2 years of use. BUUUUUT....the they replaced the bushing under warranty. So their customer service is top notch. I switched to a JBR mount.

Here are the differences....so go with what your needs are:

Cpe keeps your motor from hitting the fire wall when you take off, but if you really trounce on it, you'll still get wheel hop. Except with the air conditioning on, there are little to no vibes after initial break in.

The JBR dogbone style is a different animal. You can take off like a bat out of hell and roast the tires with little to no wheel hop. However, the vibrations are almost always present. You can drive the car in certain way that minimizes it to certain degree and this will make it bearable.

I enjoy the drivability of the JBR mount, so that is what I stick with. I feel like I'm faster as well as more planted with better shifts.

Just my opinion

You didn't have the Stage 2 C-PE mount though....

...unless you got it waaaaaaay before it was available to the public... ;)

True. It was only the stage 1 mount, so I guess it's a moot point.

Yeah, completely different design. Much better, IMO.

I love my mount, but they are pricey as shit. I think its a great everyday mount, but if I was really going to beat the piss out of my car, I would get the JBR dogbone. Not saying the CP-e mount can't handle it, because I do beat on it from time to time, but I think real durability lies with that 88d, in the context of beating the shit out of it.

I may have to disagree with that. Durometer cannot make up for a poor design all by itself. Not saying that JBR's design is bad as we all know its much more durable than stock but its still based off of the same poor bushing orientation as the stocker which will not keep the torsional forces at bay as well as the stage 2 orientation.

You would, you just love tagging me, I've got to be on keyboard speed dial lol. @lilred; Here's my shamless plug, I've now got a set of flawless 13' pu wheels for sale on friday once I have my new ones put on!

Has everyone forgotten about the first dog bone mount for this car, the TRZ?

I'll concede ignorance for who came first between trz and medieval (who also sold a dog bone). But trz isn't a sponsor while jbr is. So if you go dogbone, I'd endorse jbr.

No shit? Let's not get started on Medieval! TRZ literally makes 2 parts for our cars, so I could understand why not sponsor. I'm just throwing other options out there!

Trz is a great option. I actually have the rmm and tmm from them. I just don't know if they were before medieval.

I ordered the Cobb mount the other day so I'll report back when it's installed.

The Cobb mount is in! First impressions; definitely stiffer! You can really feel it when the car is cranking to start and when blipping the throttle at idle. Once on the move and past 1200 or so rpm, you can't feel any vibration. Wheel hop and toque steer are much improved as well...

just installed the cp-e 2 tonight. had failed street unit, difference is amazing.....

What's up with all the noobs raising threads from the dead? :slap:

bring out your dead!
