What rear MM?

[Nue]

There doesn't seem to be a general consensus on which mounts are recommended. Browsing over at the "other" site, I've noticed that it's mostly been broken down between the Street Units mounts and the CP-E's. Thoughts or suggestions? Still on the fence with this one as just waiting for the powertrain warranty to whittle out before I make a decision.

[Sport6]

A lot of people here run the TRZ Poly mount. Its a good mount and cheap. CPE is also a good mount but its hard to get one since they seem to always be back ordered.

I wouldn't recommend the 2piece from Street unit, or anyone, because I had the Medieval 2 piece and it came apart on me at the center bolts. Ya I know it was Medieval compared to Street Unit but its the design I don't like anymore.

So my suggestion would be the TRZ or the CP-E

[TheRealDefman]

My TRZ is suiting me just fine.

[Darth Vader]

Stock + Epoxy! (yippy)

[dizzin9]

trz or cp-e. NOTHING ELSE.

[SubieKiller3]

whatever you do, dont get a medieval mount. i say go with the trz poly. i have one sitting at home just waiting for me to install. its definatelly a good bang for your buck for what ive heard. you can get one from PG for only 100 bucks when the cpe and the SU mounts are around 120-130.

[Nue]

Yeah I read some of the horror stories with the Medieval's. Definitely not considering those. How is the stiffness on the TRZ? I haven't really come across many reviews for those yet. I was leaning towards the CP-Es as I wasn't looking for an increase in NVH but now I'm intrigued by the TRZ. That and the CP-Es seem to be back ordered as well. Not really looking for inserts as I don't trust the stock mounts and price is a small issue for something that seems to rather crucial upgrade once the warranty runs out.

Actually The 2 piece design, if made correct so not from medievel only SU, is stronger then the 1 piece. By haveing the 2 piece it splites the shear and tensile strength of the mount is split and concentrated at the strongest part of the mount, rather then spreading and multiplying accross the whole mount and effecting either end.

MY sugestion would be the SU mount.

[derspi]

Whichever mount you go with, you will get increased NVH. You won't be able to avoid this, even with the CPE.

[Captain KRM P5]

we've sold over 450 TRZ rear mounts to date with orders pending in the bin right now, so they have to be doing something right :)

correctly said. I would, if i did it over, buy this mount over the SU just because of the price. But the SU mount is a great product, just like the TRZ. You would be spending more $$, for a stronger product. But not sure if the extra strangth is needed. I will probably even go with the TRZ Trans mount.

But what i said is true about the 2 piece design being stronger. Same concept of welding 2 pieces of metal together. They become stronger, and you have less change of any bracking under extreme load
(but if you break a TRZ mount you really F***ed up the install and should not be working on a car)

I'd like to know what you base your decision on? Some scientific proof or just your own personal preference? I have been using the SU rear MM since day one in my car with absolutely NO issues at all. Please school me on why I'm using the wrong rear MM... I'm wide open to hearing why the 2 piece design is inferior. I autox and DD my car (and I drive hard) so I've put this piece through it's paces, and it's still working for me. PERIOD. Look forward to a response to my question, "why is this design inferior?" By the way which mount are you using?

[mr_mazda329]

TRZ Poly. Hands down. Strong and not that bad on the vibes other than my e-brake button buzz

[Nue]

@djza2u1 and derspi
I see. Thanks for the input. I'm already expecting an increase in NVH but just not a drastic degree like many seem to be bitchin' and moaning about on the SU mounts. It's still going to be my DD, and hopefully nothing that jars my fillings. Are you guys on an aftermarket mount?

@funksilver07
Guess I'll go out of the way and say that he listed his reason for thinking why he didn't like the two piece system, namely, the entire Medieval fiasco. There were some few threads about it on the "other" forums on how they utterly failed and Medieval not backing them up. Nothing was said either about why they were inferior either. I have no issues with the design, other than the supposed drastic increase in NVH due to the (my guess) two piece design in making sure this damned mount stays in place.

But like djza2u1 says, because the extra precaution is somewhat questionable, I'll most likely that i'll be going with the TRZ when the time comes then.

[derspi]

Yes, I've been running a CPE 60-duro for a few months now and although the improvement was initially drastic, after it has broken in, the improvement in shift feel and engine movement has decreased a bit. A slight amount of play has returned over the course of several thousand kms. with the break-in. However, the amount of vibration has always been quite minimal - only some increased vibration when taking off from first between 900 - 1,500 RPMs. Other than that, it's smooth and vibration free so it really does make a great DD rear mount. I'm looking to add an engine torque dampener in the very near future to take away that little added bit of movement and further improve shift feel.

[djthom]

i got a used TRZ with your name on it!
70 shipped?

[BillTheCat]

Added my order to the pile yesterday afternoon. Been wanting to upgrade for a while, and it's time. Hoping this will be as easy as the how-to makes it sound. Hehheh.

[Kain]

Rear MM is one of the easiest and most useful mods for this car. My 75-duro CP-e transformed my car just as much as my RSB or intake.

BTW, highly recommend the CP-e. Even the 75 duro doesn't vibe annoyingly.

[Mr_Boom]

Got the TRZ Poly mount a few months back and have been pretty happy with it. Installation is easy, cuts down on wheel hop for AutoX racing, and only causes major vibrations when taking off in 1st gear from a stop.

I haven't kept up as much with the newer Medieval mounts - but I didn't think that there really was much of a problem with the 1st gen 2-piece design. We know about Sport6's problem, but that was basically just a fairly isolated incident since they forgot to put loc-tite on it.

Were there many other problems with the 1st gen Medieval rear mm?

For those wondering about strength of a 2-piece design, Medieval did some testing and posted up the results.

If anyone is curious. This is just one such case of the Medieval mounts.

And djthom, sorry, but I'm probably going to be going with a brand new one as I really don't want to risk it with a used mount when I'm already incredibly skeptical of the stock mounts. Saving a few bucks and putting in a mount that's already been used won't give me a safe feeling either. But might I ask why you are you trying to sell this supposedly great MM?

How about the model that is shaped like the stock unit, but with better rubber.?
dunno which brand that is, BUT, l bet the dealer tech would not no you've pulled a switcheroo

[meicalnissyen]

Stock + Epoxy! (yippy)

I did shoe goo on my corrolla mounts fore awhile before I replaced them. Had no idea I was being so cutting edge

Oh I used the 75 duro shoo goo, cold pour technique (killit)

[meicalnissyen]

Topspeed apparently. but it would need black paint to pass visual inspection

[nbk6kp10]

Has anyone tried the Topspeed mount?? I saw it on ebay for $80.

[Nue]

@meicalnissyen

Not really interested in trying to bs the dealer as should something actually happen, they'll be investigating the parts anyways.

On a side note, our cars have 3 engine mounts correct? Any other mounts we have? Thinking about switching out all 3 and calling it a day.

[HOBDisease]

Installed my TRZ poly today, quite a bit of vibrations and it's pretty noisy, but I'm sure they'll cut down a lot as the mount breaks in. Shift feels good, no wheel hop, cheap, and it's a great product. Install was easy as hell. I thought the install was "easier" than putting in the Cobb SRI, took me 5-10 minutes plus time to put the car on jack stands. Another thing, I don't believe there was any issues with the TRZ, confirm with Ken about this. Go TRZ or go home.

you are correct. and thank you for the kind words.

[HOBDisease]

No problem bro, it's a great product and PG's one of the best online stores I've bought from. Just let me know if there's any specials or "hook-ups" going on, I'll be sure to pick up a couple parts on my shopping list. Thanks again.

[Captain KRM P5]

we've got some new products in the pipe line. new pipes in the pipe line ;)

[HOBDisease]

New pipes in the pipeline... I like the way that sounds, no homo. What are they?

[Captain KRM P5]

lol what?

will be posting some pictures i hope tonight with sound clips.

[HOBDisease]

What "pipes"? Down or cat-back? And isn't there an intake manifold in the making also?

[Captain KRM P5]

intake manifold is a ways off. i'm waiting to see what DCR is coming up with. we're talking to representatives over there to see what they have and do not have in the works so we don't overlap. i'd rather collaborate than compete.

[HOBDisease]

Yeah a whole piece of the cake is alot better than just half in some cases. What do you guys have in the making?

[Captain KRM P5]

new manifolds, catted shorty downpipes, resonated/mufflered test pipes

[HOBDisease]

Need any test mules? Blah ya'll probably got plenty..

[Captain KRM P5]

i have one lined up, but may need more

[HOBDisease]

Shoot me a pm if you do, how far is Grayslake from Indy? Maybe I should mapquest it.

[Captain KRM P5]

about five hours

[Sawce]

Regarding the TRZ rear MM...

The install is simple, the price reasonable, and the performance improvements are significant. Definitely great bang for your buck.

It goes with out mentioning, yet I am, that Ken @ PG has this on lock down among other products, so in case you did not know where to go already...

CP-e is pretty good I love mines.

[BillTheCat]

Just ordered the TRZ Poly mount from PG 2 nights ago. Got immediate confirmation, and 2 status e-mails so far. Looks like it shipped. Love the communication, appreciate being kept updated on status. Muchas gracias.

thank you for the order sir

To derail my own topic, I'm considering swapping all 3 mounts and getting an ETD as well. Having my engine bottom out on me is giving me one too many nightmares (notcool). So, time to go balls out (uhm).
