JBR Trilogy - holy vibration/noise
 

I expected a noticeable jump in noise/vibration when installing the JBR Trilogy (80a) set, but jesus it's insane at the moment. I went from stock mounts to 3-way 80a all at once, so that probably explains that. My question is - how long (on average) does it take for these to quiet down? I understand that they will never be as quiet as stock (which is fine), but I'd imagine they "settle" at some point...

Also - if this thread is in the wrong sub-forum I apologize - didn't really know where to put this.

Until your balls drop, could be next week, could be never. :D

They don't really ever settle. Should have gone with the Damond Motorsports threesome mounts. The DM mounts are still louder than stock, but much quieter than the JBR trilogy. @Farhan@DM; makes some great parts.

Well it's a bit late for that as I just had these installed today. I'll definitely keep that in mind though - if I still can't stand it in 5k or so miles I guess I know what I'm doing.

you should try them with a BSD

BSD?

Balance Shaft Delete... you do not know vibes yet

They'll always be miserable. Mine were for the 2 years I had them in.

after about 1000 miles , but you will still get some vibe though 2000 rpm to 3000 rpm but should not be as bad?

I just turn my music up and all the rattles go away

I have em on my gen1, and they do settle down a lot. Just need to drive it. Most searching will snap that it takes time to settle.

Just wondering, why did you decide to go trilogy mounts right away? Most people try upgrading the RMM first, then later decide to upgrade the other 2 mounts or stay with just the upgraded RMM.

Try driving with the windows down, that seemed to help lower NVH when I was still on the DM RMM.

I don't have the space or tools to do the work myself, so figured I'd get all 3 done at once to save on labor a bit. In hindsight this is definitely overkill. I only drive it like once a week, it's definitely a toy, so I'm pretty sure I'll get used to it. And if I don't, I can always rip the other 2 mounts out ;-)

Welcome to the wonderful world of "racecar problems"

I have the DM side mounts with CPE S2 rmm (same basic idea as DM rmm). Even if you go with these over the JBR it will still rattle your teeth loose compared to stock. Basically, you need to determine how dedicated you are to having a "racecar" toy. For the average modder I think a nice rmm and corksport tmm insert does perfect and has very minimal vibes.

His racecar dedication has been confirmed with installing All mounts all at once.

Quite stifled that someone would buy and install all three with researching the nvh issues, especially with the jbr trilogy, and complain about it.

I do like 90% of my driving in that range lol.

If you have a jack and a ratchet you basically could have did the rear motor mount in 20 minutes with the help of a how to video. Then decide from there if you need to upgrade the others. So let this be a lesson to you.

Buy some basic tools and don't make expensive mistakes. I don't even wanna know what you were charged for labor. Just install your own stuff for now on.

Yeah, I'll admit all of my research went into the suspension components and I just assumed the JBRx3 would be fine. I don't dislike the noise to be honest, I'm just not sure how I'll cope with it on long trips (not that I do that many with this car)

It's not just a matter of tools, but a matter of space - I live in Hoboken, NJ - so driveways don't exist at all. Garages are a rare thing as well.

I've been to hoboken many times. You could replace your motor mount in a tight parking space.

Didn't even notice you're from Brick, really not far from here at all. Small world. You're probably right - but as I said, I just figured I'd do all 3 at once and kinda just shelled out for the labor

Yeah man. You're like an hour away.

I just don't wanna see you make the same mistake in the future. Once you research a mod and can wrap your head around it, you'll realize its pretty straight forward and doesn't require much space or even tools... It can save you money and save u from situations exactly like this.

If your Speed is truly just a toy then I think you made a good move getting the mounts. The reduction of torque steer is worth the vibes IMO. It might take you a while since you only drive the car once a week, but the vibes WILL eventually die down a bit. I think it was about 2k miles for me. Now the only thing that rattles routinely is my map light housing. There are a few other rattles here and there, but nothing constant anymore. The vibes I barely notice.

I DD my Speed in the summer and don't mind having the JBR trilogy at all. With the windows down I can't hear any rattles. Personally, if I were you, I might have gotten the DM mounts over JBR, but JBR isn't bad either. The only reason I went with JBR over DM is because DM mounts didn't exist yet haha.

Keep the mounts, embrace the vibes, and grin from ear to ear every time you mash the throttle.

same here due to traffic calming measures , speed camera's every where, were I live :AR15firing:

Try living in Chicago. There's probably more speed/red light cameras than people

This is why I went back to stock on the PMM (was Corksport, great mount, vibes in that 2-3k range with resonance)... CPE S2 rear and watch for leaks on the PMM... good compromise and the only vibes I get from it are on cold start and AC on....

Get rid of the JBR mounts and get Damond Motorsports Mounts. You won't regret it at all.

I was fully mounted with CP-e, felt great, then swapped those for DM mounts. The car feels awesome, solid, and stock like to me.

I would just swap the passenger for the Damond and the rear for the CP-E. That would quiet it down quite a lot.

edit: @mrand01; forgot to mention, I've been in a Gen2 MS3 with all JBR 80 duro mounts and they do quiet down quite a lot after a while, but this takes a couple weeks for most people.

I drove around a bit more last night, and I'm actually starting to enjoy the noise/vibration. Go figure. That said, my fiancee hasn't been in the car yet, and she's bound to hate it, so thanks for the advice!

Eventually, if you are like me, you just do not notice em.

I said the same thing after the DM RMM was installed. Fast forward 7-8 months of normal daily driving and I got tired of the NVH. The DM RMM is a great compromise between a daily driver and racecar mount, leaning more to the racecar side. The compromise being, it gives you racecar performance while still being livable for a daily driver. The benefit being, you don't need to swap mounts when you go to the drag strip or track. It shines when you drive your car aggressively, all the time. Need to pass someone on the highway, downshift quickly and go WOT. At the front of the line at the traffic light, launch your car and flat foot shift when the light turns green. Taking a 90 degree right hand turn at an intersection with a green light, downshift to 2nd and aggressively power out of the corner. Those are the times when the DM RMM is so fun to have on your car. Since you said your car is a "toy", I bet you will have fun with your trilogy mounts as long as you drive it like a "toy".
