Motor Mount Inserts vs. Rear Motor Mount Pro's n Con's

[Dre]

Heard, and felt, my engine hit the firewall today during a hard launch and it worries the shit outta me.. I've noticed there's Inserts and actual replacements, but which is better and why? I know most people have the RMM, but I'd like the hear the reasons why.. And what are the benefit of using the inserts over the replacement mounts, if there are any?? Thanks!!

I'm putting my inserts in today, so I'll let you know what I think...but most folks say that the inserts don't hold up too well. Yes, they're a third the cost, but they probably won't last for more than a few months. I'd go ahead and buy the full rear motor mount, and save myself the hassle.

Try some 3M window weld. Let it cure ~3 days in warm weather/heated garage.

Why mess with inserts when the new MM is prolly designed a lot better. It's like using a bandaid to cover a gaping wound....IMHO of course.

[JS + MS3]

I heard it hitting the firewall once when I accidently turn on the engine when the car was left in 1st gear. It was scary, I though I hit something really hard.

get trz rear mm and tranny mount.. you wont be disappointed. makes car much more fun to drive

[IshiKage]

inserts are a temp solution. i had inserts, i felt the difference for a little then i felt like i didnt have inserts anymore...just go with a RMM from jump street

[WVDPS643]

Anyone running the turbine tech mm?

[Dre]

Thanks for the input everyone.. I was gonna go for the inserts, but why waste time and $$ cuz eventually ill want the RMM.. 240mazspd3 is the Mace Windu of these forums btw

You're gonna want to get the replacement MM. I have the CS inserts right now. I like them. They're a very subtle change. They do help, but not like a whole new mount will.

Stay away from delrin mounts unless you want all that vibration and noise.

[Lex]

Had the CS inserts. Nice improvement and no extra vibration. Now I have the CP-E mount. Definitely extra vibration but better response as well. Increasing idle RPM to 850-900 helps when the A/C is on.

[erod550]

I don't get why people complain about vibrations so much. With completely solid mounts, not polyurethane like the ones most people have here, I only noticed the vibrations in my SRT-4 at a stop light with the AC on. If you're that sensitive about vibrations, why not just leave your car completely stock. Then it will be extra smooth for you. Me, I will give up a little bit of comfort to make the car perform better. It's not like these cars have a super smooth ride anyway. Better not get stiffer springs cause then I will feel more bumps in the road. Why didn't you get a Lincoln Town Car if you wanted a cushy ride?

This is not directed at any one person. Just a general rant about all the whining about vibrations.

You don't get it man. I had the TRZ delrin mount on. It's fucking violent. Too much for a daily driver. Sure, the power transfer was amazing as well as buttery smooth shifts, but it felt and sounded like the car was going to vibrate apart. No joke.

I'm no fucking wuss, I can handle vibrations. But, when my 2008 Mazdaspeed 3 vibrates just as much as my 1956 Ford pick-up, that's where I draw the line. In this day and age, you don't need that much vibration for better performance.

I save the delrin mount for track days or as a back up now. It sits in the shed most of the time. The inserts are very cheap and effective, but doesn't help with wheel hop or direct shifts.

I've had both the SU and CP-E RMM and both are a great improvment over stock. The SU RMM I had provided great results for roughly 8 months then the bushings started to crack. I'm sure SU would've provided new bushings but I decided to just sell the mount and try something else. Now I'm running the CP-E and it's been great!

[ATAZ]

I just installed the SU MM- very nice piece, solid construction. It took loosening and removing more bolts than the TRZ needed for the install, but when it was done and installed...very happy customer. Smooth shifts, no crazy engine shifting and the vibes are there but not agonizing. Cpe, SU or TRZ poly are all good choices.

[banditscout]

Ok, so here's my update. I've had the CS mm inserts in for approximately 2 months now...and the shift feeling is essentially back to square one. In short, don't waste your funking money on these...save your pennies and go with the SU or CP-E rear mm's. Oh...but the idle vib's are still there

LoL.. man this thread is old.. ive had my CPE RMM in for like a lil over a month now.. love it to death.. i love feeling the vibes.. in the shifter, in the pedal, throughout the car.. feels more alive..

[mzdaspeed3]

Lol I noticed that Dre I started reading the posts half asleep and I was like hold up this dude has a rmm already wtf.... then the coffee kicked in and noticed it was like 2 months old. haha

[NCZ13]

I read a corksport article talking about how durometer measurements don't matter and it's the design that is more important, but that's kind of hard to believe that of we have the same exact mount and have 3 different options for bushings that there won't be a noticeable difference.
