New and Improved MAZDASPEED 3 70a and 80a Rear Motor Mounts
 

We changed the design of our 70 and 80 mounts to be more like the 88. Billet mounts have always been difficult to tighten and keep tight; no matter who they're made by. The molly design is stronger, not the it needs to be any stronger than aluminum, and it's easy to tighten and it stays tight.

We been testing this design in dozens of cars for just short of year now and it's been perfect. We also have more control over production and quality of these mounts which has always been very important to us.

We're always looking at ways to improve our product line.

I'm already fully mounted, but I can't friggin' resist! Thank you Jamie and everyone you work with to keep improving our cars and your products. James Barone Racing, a company that just can't settle for "Good Enough."

This came outta left field, Mr. sneaky! Good thing I already have the 88, but this is sweet.

You know a vendor is good when they come out with improved versions of a product that has been on the market for a long time AND is already trusted by the community, doesn't "need" any upgrades and sells just fine.


Rock on Jamie!

:headbang:

Not only is this a product improvement but, it also helps us to be more efficient in several ways. Since tooling and setup for the molly 88 is very similar to the new 70 and 80 tooling and setup, we can save time and money. This allows us more time to manufacture the numerous other parts we make, to focus more on research & development of new parts, and to pass some of the savings on to our customers by keeping costs down. It's win win for everyone.

We've learned a lot over the past 3 and a half years and we listen to our customers too. We recently improved our transmission mounts and we've made a couple minor improvements to our catch can kits as well. This is business for us now, but it's not one that's all about making money.

Cheers!

ive always said that the dogboners are the only way to go

Trade in program? LOL
Same pricing as old mounts?

What changes were made to the OCC kits and when were they made? Anything significant? @jbarone;

Reviews I've read said that your old mounts were way to harsh. Has that been improved? I'm not new to vibration, the one I have now has tons of it down low. I'm looking for a new mount soon so, I'll definitely check this out when I can read some other members reviews.

Just fittings really, nothing with the can itself.

Way too harsh..lol Out of all the rear mounts we've comparison tested, ours exhibit the least amount if vibration...Excluding the 88 and even that mount exhibits little in my opinion and that of many others as well.

Cool, I've only ever tried the corksport motor mount and it my opinion it transfers too much vibration when shifting into gear. It's become a very annoying distraction. I'll try this one out. I'm sure I'll love it.

Which mount?

I was leaning more towards the 80 because I hit the firewall sometimes with my corksport 70. How noticeable is the vibration difference between the 70 and 80?

It's not bad at all. After break in the only time you may notice the mount is with the air on and even then I think it's very reasonable. I'm sure you've seen the reviews about our mounts and I don't think I've read one complaint about vibrations from our 80 duro.

Sweet I'll go with that one. I have a set of HKS coilovers that I'm waiting to sell. Once they do I'll put in an order for an 80. Thanks Jamie!

By the way my sway bar arrived yesterday. That thing is awesome. Can't wait to install it.

I've only every heard one complaint about your mounts jamie, and it was the oil change guy thinking something was wrong with my car. lol

I have the 80 all the way around, and its awesome. my rear view is a little on the useless side, but that wasn't from the rear mount.

I too have 80 all the way around. The rmm was put on first and that was not really that noticeable. I would probably buy the 88 if the 80 wasn't such a bulletproof item and would break. Nothing like a vendor putting out an item that you replace because you want to, not because there is something wrong with it. lol

:You_Rock_Emoticon:

About to buy the new 80 along with powerpath intake
Very excited my 1st jbr products

Good first mods, now save up for Access Port and fuel pump internals and unleash the powa with a stratified OTS tune!

It would be my honor to be your first.

Already ordered also :)

Good on you, enjoy the new parts.

Thanks parts have been ordered:biggthumpup:

Thanks sir will do

Looks like a nice improvement. Too bad I ordered your older model a month ago! :(

Just bought the old version
 

I bought the old 80 RMM on the 18th. Wish I had waited two days.

FTFY.

Crappatalking on my big-ass phone.

Please take a moment to read this post; it's very good information about aluminum rear mounts.

http://www.mazdaspeedforums.org/foru...ml#post2103326

It's so well put and exactly why we redesigned the 70 and 80 duro mounts to be in a similar housing like our 88. ALL aluminum mounts, whether they're made by SURE, Corksport or CP-E suffer from the material wearing and coming loose over time. You simply can't get the big forks from a billet mount to clamp tight enough.

That post sums up my conclusion about my used JBR 70 duro RMM. I'd get under there, tighten in, everything is good for a few days, and then I hear and feel the engine rocking back and forth a few days later. Sooner if I romp on it.

I mentioned in my mounts thread that I drove a fellow Nator members car that was fully mounted with JBR's 88/80's and it was nowhere near what I thought it would be like. I've given up going to the drag strip until I get these in.

I have 88 just installed yesterday. Wow crazy cabin vibes but I freaking love it !!!!

What vibes?

probably tappin dat ass

Hahaha I've gotten use to it already after 2days

I just finished installing the shifter kit and the new 80 duro mount and holy shit! Everyone always talks about how drastic the change is, but you really need to check it out for yourself to understand just how drastic and enjoyable it really is. I just fell in love with the car all over again!

Glad I could help rekindle your love affair with your car.

We are very pleased with our shift kits and the redesigned mounts, thrilled you are too.

ENJOY!!

Installed my brand new JBR 80duro RMM last Saturday at our So Cal NOTOR meet and I absolutely love it thus far!

The vibrations aren't too bad at all. I really dig how the car feels and how the shifts feel now. This plus my JBR CAI and Stratified OTS stage 1 map, really woke my car up and made it even more of a blast to drive.

Thanks for the excellent products @jbarone! You guys really go above and beyond. :bigok:

I'm glad you like the new mount....and the intake too!

We've been overrun with orders for the new molly 70 and 80 duro mounts so it would appear others are liking them too.

-J

Can anyone compare the 80 to the 88 in terms of NVH?

Get the 88.

Trust me.

The 88.

Yes yes. It will happen on july 4th @ 12:01 CST when everything goes on sale. I was just curious.

Just installed my 88 this morning. Those vibes and cabin noise are intense. Did not expect that much of an increase over my corksport mount. :11: Haven't done any testing yet, just some easy pulls in 3rd and 4th. I'll do some when I get home from work. I'm going to let the mount break in for a couple of weeks and if it doesn't die down enough I'm buying one of these new mounts and sell my 88 molly.

Doood! There are a TON of threads that say the same thing you did when it first got installed, I would use miles driven rather than a couple weeks as a break in time. It will get better, if you don't believe it find someone who has had it for a long time and take a ride.

That's what I need. Someone around me who has one broken in. Anyone in socal want to volunteer? Just took my car out for lunch with some of my colleagues and the vibes were just embarrassing. My whole cabin was rattling like a motherfucker. I know it's a new mount and needs time but I want to have a semi comfortable car. I'm going to check the torque specs when I get home, could be that my mount is loose.

The 88 settles in real well.. Just give it time, and I'm sure you're NOT going to sell it!!

Sent while being stupid.... What else is new..

I installed the JBR 80 duro RMM a few weeks ago at the last NATOR meet and at first I was pretty shocked at how intense the vibes and cabin noise was too. But really dude it does go down when it starts to break in.

I've only driven my car about 600 miles max since I installed it and I don't really notice it anymore. I only feel some vibes way down in the low RPM range and then its as quite as stock once you get going. The vibes and stuff are only going to get better the more miles I put on it. Granted there will always be some vibes but I'm sure it won't be too bad.

Since you got the 88 duro RMM, I imagine the vibes would be worse and would probably take longer to break in. Although I wouldn't think it would be that much worse.

Did you get the 80 molly or the first model?

I don't know how best to describe the vibration. It's almost like my car is a ringing cellphone on vibrate. I guess I'll wait and see after the break-in period. Should take me a month plus since I only drive 100 miles a week. I think JBR is worth the wait.

Vibrate, yes, but it shouldn't "rattle". Then again, I have all 3 mounts so I never had the 88 RMM alone.

I got the new Molly 80duro RMM from JBR. :headbang:

You need to take me for a ride. I wanna feel your vibe.

Well I'm free this weekend if you want to ride the big one. LOL

Damn... I'm going to an out of town wedding this weekend. The big one will have to wait. :sad2:

LOL

Just let me know when you'r free.

:smlove2:

Patience, dude. First 500 or so miles are rough. You should be expecting that. Next 1000 miles are better. After 1500, you'll barely notice it, and it'll continue to mellow. I've had mine for about 3000, and while I know it's there, it's not punishing like it was when I first installed it (and you're experiencing now). NVH went from a 7/10 to a 2/10. And no more engine banging around or wheel hop, which is ultimately your goal with a RMM.

The other thing, from what I hear, is that you have to make sure that you installed it exactly as the directions say. If you do it in a different order, you could end up with more NVH as a result. Reinstalling it correctly remedies that problem.

I had a corksport motor mount (not the inserts) before this one so I'm not new to mounts. I'll wait till all is broken in, in a couple of months and see where everything stands. I'm sure it will be fine.

I did launch yesterday and was very surprised by the decrease in wheel spin. With my corksport I could get the wheels to stop spinning in first and second. With the JBR 88 I had some spin in first but it went away quickly and I had almost none in second. That was pretty cool.

FYI, I installed everything exactly like it said in the instructions.

I think you'll end up liking it. I really only get vibes sometimes at this point. I was going to say that I can feel it with the A/C on, but today I forgot that I had it on and couldn't feel at thing.

Looks like everyone is enjoying the 80 and 88 mounts, but I was thinking of going with the 70s. Can someone provide information as to whether the 70s (I'm going to get all 3 mounts) are even worth it. My car is a brand new 13 and, to be honest, I'm not having many problems with the stock mounts. I won't track this car or launch it, just want to be sure the car hits each gear like it's supposed to when I shift at redline.

The 70's would be great for what you're trying to accomplish. The 80's will give more head room should you decide down the road to track the car and launch more. Hope this helps.

-J

fyi, I don't redline the car...I meant shift at the appropriate rpm. I know going passed 6k is pointless on a stock car. Don't want you all thinking I'm a newb.

Thanks, it does. So with this revised design, we shouldn't see premature wear or anything. As with any one of my DDs, this car will see all sorts of weather conditions, etc. Is there advised maintenance for these mounts?

You should see no premature wear from our mounts and there's no maintenance required. Follow the installation instructions, check them after a few hundred miles and enjoy.

You're going to be amazed at the difference between the stock rmm and JBR's stuff. Even if you don't do anything aggressive, it's like night and day.

(Also, consider at least the 80a mount. I have the 88 and it's not very harsh at all, once it broke in.)

Good luck!

I just installed my jbr 80rmm today and all I can say is WOW! It's great and really improves the car. I was skeptical about NVH, but it's honestly not bad and no where's near what I expected. I actually kinda like the vibes, but to know its going to have even less once broken in is a plus because I don't mind it now. Next two mods will be jbr 80 passenger and tranny mounts, even though my cars complete stock otherwise lol I just like the thought of being fully mounted ;)

Glad you like it. I bet by now there are little if any vibes from it?

Correct there is way less vibes now, I can hardly notice it.

Got the mounts in the mail today. Full 70 trilogy. Can't wait to get them installed this thursday.

I'm sure by now you've gotten them in...How they feel?

I have 1500 miles on them. No one complains, car drives smoothly and feels nice and tight. To be honest, I recommend getting the whole mount set vs getting a more aggressive rmm. My car feels a bit sharper with the 70a than the car I drove which only had an 80a duro rmm. Plus all my mounts will wear evenly.

I'm asked that question a lot. Is there less vibration with a full set of mounts or...?

Anyone?

I don't even notice the 88 RMM anymore, I will let you know what I think once I add the 88 TMM and 80 PMM.

I put on the 88/80 combo and after the break in period, there is still some minor vibes, but things only "rattle" around 2-3k. The PMM still vibrates my rear view mirror and I've had the mounts on since June. That'll never go away.

I had more rattle when it was just a 70 duro RMM.

Also, the tranny whine is either gone, or I just don't notice it anymore. I was very pronounced when I first put on the TMM.

Got ~7000km (4500miles) on a set of 80's
Rear view mirror vibrates and if I get it JUST right (wrong?) there is epic vibrations on no throttle deceleration from 2800-2400rpm.... But it's extremely hard to replicate deliberately.

Other wise my only complaint about them is we have a lot of 60kph (37mph) and 100kph (62mph) roads here in Australia, and sadly in a gen 1 that's 2500rpm in 4th and 6th respectively... This transmits lots of noise into the cabin.
60kph is easily fixed by going into 5th, but it's a bit unpleasant at 100kph in 6th... 110kph is fine (2700rpm)

With 88 RMM, 70 TMM and 70 PMM, ride and NVH feel perfect for me. Very slight rear view mirror shake blur, but not like you can't make out the shape behind you being a car. Slight steering wheel shake only with AC on. TMM introduced the only strange noise in the transmission chatter with clutch out at idle.

I changed a year ago from the discontinued JBR aluminum frame 70a RMM and stock TMM/PMM, and the vibes were quite a bit more, but not in a solid way.

I feel like the vibes with A/C on are negligible. Nothing like the rattle at that sweet spot @SarcasticOne mentioned.

In my opinion, if you're trying to squeeze every bit of performance out of the car it's a non issue. I got more joy out of the car after I put mine in.

Everything @Cheapspeed; has said is spot on. There's that "sweet spot" at a certain RPM. 70's all the way around and put them all in at the same time. Only things that's hasn't settled is the clutch out in neutral you get that transmission sound. Just the sound of solid connection ;)

But to Anwser the question I don't think vibes were extremely noticeable.

I have to decelerate at just the right speed, ie 3s to go from 2800-2400rpm
Do it in 2.9 or 3.1 seconds and it's fine... As I said it's extremely hard to replicate, and I've tried a lot... All I can think is I'm magically hitting the exact most unbalanced points of the rpm in just the right way...

Put the 88TMM and 80PMM on last night. Can hear the transmission clearly but I don't notice any more vibes over what I felt with just the 88RMM.

I will say the car almost felt slower but faster at the same time. The motor doesn't move at all so the car stays flay and smooth while using heavy acceleration(why it feels slow).

To describe it in geek terms, it's like JBR gave me inertial dampeners for the car so it is just pure acceleration.

I've had 70 side mounts for 9 to 10 months and coming on 20k miles. My dash sounds like it's going to rattle apart, my sun visors rattle, door panels rattle, hatch rattles, both side mirrors rattle, glove box rattles, shit in the center console rattles, rear view can be unusable at times, and I'm very tired of hearing my transmission. Also if I'm coasting near 80 in 6th and give it just a tiny bit of gas the whole car goes into a death shake. If you're as hypervigilant as I am I do not suggest these mounts.

Everything is very planted but the mounts have not gone unnoticed.

Glad I went with the stiffest mounts if the 70s shake that bad, I notice no extra felt vibrations, my rear-view mirror shakes no more then it already did(and I have a 360mm broadway mirror) and my side mirrors don't vibrate. I do hear a vibration from the broadway mirror I didn't hear before. I actually feel less vibrations when starting my car, letting it idle with the AC on and when taking off from a stop at a very low RPM.

Now the transmission noise on the other hand, you can hear that loud and clear if you have the windows up, if you put the windows down it isn't as loud. Getting on the gas you can really hear the motor and trans but I like the sound. It also helps me keep from driving how my wife hates.

My wife rode in the car yesterday for the first time since putting the mounts in (all of 15 miles on them) and she commented on how my car was making funny noises. I told her it was cause of the cold and once it warms up it should go away. When I installed my 88RMM she thought my car was broken. At this point with 15k miles on the RMM she doesn't notice it at all. She also didn't notice any extra vibration at all with the side mounts freshly installed. I'm hoping the noise settles a little and/or she just gets use to it by the time it gets warm again.

Either the car is a POS rattle trap or something is loose. You should not have anywhere near that kind of vibration going on. I would inspect them.

I'm pretty sure it's my car, I've always had some vibrations but it's getting worse and worse over time. The dash and door panels really went nuts with the mounts though. All bolts were torqued and loc-tited so I don't believe they're loose.

Just because you don't believe they're loose doesn't mean they aren't loose.
