new solid rubber PMM option

[jack_hammer]

i wanted to throw this out there in case someone is looking at passenger mount / passenger side motor mount options before i get to it.

if you don't remember, top speed used to make a solid rubber bushing PMM for the 3's. they were a mild upgrade over stock. no leaking fluid and no excessive NVH... just decreased engine movement. and, these are only $73 or so.

a refresher on the old top speed mount:
TOP SPEED AUTO ACCESSORIES, INC.



so in searching i found this option:
Roca USA (owned by megan racing)
Roca USA
part # RC-EM0002A




i called the manufacturer and verified that these are solid rubber mounts. so, essentially, this is just like the old top speed mounts, but actually cost less. you can also find these on ebay or amazon. so, there it is. i intend to buy and test out in the next month or so, and will update then.

until that time, feel free to discuss!

interesting..
anyone to recall their experience with those?

Might be a good alternative to those with the BSD and want something that holds better then stock

I was thinking the exact same thing

[Nliiitend1]

I'm a bit suspicious about that mount being anything more than an OEM-like aftermarket replacement, regardless of what someone on the phone at the manufacturer says...

Were they asked if they were any different than an OEM mount with regard to construction? ...because if all they did was open a box and look at one I don't know that they'd be able to tell that it's filled with fluid...

Fwiw, i contacted an Ebay seller first. His claim was that all mounts from that manufacturer were solid rubber. I think the manufacturer said the same.

Probably sent from a toilet

You can tell by price that it's simple solid piece of rubber.
I would agree that it's nothing more than just OEM replacement.

Looks to be the EXACT same as the TopSpeed mount but without the pretty blue paint. Very tempted to order this... just wonder how vibes will be without the filled mount.

[jack_hammer]

there are lots of threads regarding the top speed mount on m3f and a couple on m247 and none of them were negative. i know of at least one member on here that used it as well and he loved it. he's not on here anymore, though.

[jack_hammer]

and i just called them again. they do not make any liquid filled mounts, they are all solid rubber. however, they also said it is the rubber is the same stiffness rating as stock. so, i don't know if that would be very useful or not.

[El_Diablo]

I would say it would be at least little stiffer than the hydraulic mount that comes stock. Hydraulic mounts, purely by nature of design, are usually fairly compressible in order to transmit the least possible NVH to the passenger compartment. I'll probably be giving this a shot in the near future.

christmas and mortgage refinancing. my shit ain't broke and i barely drive the car anymore. i'm in no rush, which is why i put this out here in case anyone else wanted to try it before i get to it.

[DeadWayt]

Giving this a shot. No more expensive than the other OEM options.

Sweet! Be sure to post up results!

Will do. First chance I'll have to install it will be either Thursday or Saturday.

[rtabagaboy]

I have the topspeed PMM. I can't say that it helps a lot with engine movement. I got it cheap and to me it does not at NVH. It is pretty mild compared to my TMM and RMM. I would upgrade to another aftermarket PMM but i hear they xmit a lot of NVH.

Upgrade to the CorkSport PMM. I just installed mine and it adds damn near no NVH, my pedals have zero vibration now.

Installing it now. Gotta give it a couple hundred miles before I make a call.

[DeadWayt]

Couple quick notes from installation: fit was perfect. No issues whatsoever with installation. I had to relocate the ground just as with the Top Speed mount, but that was painless.

I must say, it doesn't feel nearly as substantial as the stock mount, but there don't seem to be any obvious flaws with it, so I'm not too concerned.

Feels like OEM so far, but I'll update as I break it in.

[DeadWayt]

300-mile update:

For those who want OEM feel but don't want to pay OEM prices, this mount seems to do the trick. My original mount wasn't too beat up, but replacing it actually cleaned up my 1-2 shift quite a bit. For the longest time I was practically double-clutching it when the car was cold, but I don't need to anymore. Considering I had zero expectations for this mount, I'm quite impressed so far.

This is a 45k-mile 2008.5 with quite a few track and auto-cross sessions on it, for what it's worth. I think I'll be purchasing their transmission mount next (I have an OEM GenPu RMM already).

[azazelthegreat]

Hate to revive this thread, but more feedback on the ROCA mount will be coming just installed it today. will wait 300 miles post my thoughts about it.

So far the car feels smoother. I have it Paired up with a JBR RMM and a CPE Transmount.

[DeadWayt]

I ended up ditching mine after about 8k miles. It was fine in the warm weather, but the winter NVH was unbearably bad.

[jack_hammer]

what did you use in replacement?

[azazelthegreat]

I agree about the NVH. This morning it was 10 out and everything rattled in my car.

I honestly lold. But it was a rough drive home

[El_Diablo]

To be expected with any PMM other than factory. Especially with you're BSD and clutch combo.

Yeah its not that big of a deal for me.

For about 3 seconds it sounded like I had 4 15 inch subs going then it tapered down.


After work the vibes were fine.


It's obvious that I have all 3 mounts.

[El_Diablo]

You had, DAT FLEX!?

[azazelthegreat]

Oh yeah.

everything rattled. Next time ill take a video. (implying it gets this cold again this year)

[jack_hammer]

Sooo, last month my stocker exploded. It happened fast, too. I noticed one weekend a crack about a cm long. A drop of fluid was coming out. within 5 days, it jizzed all over my car. I installed a borrowed jbr pmm. 80 duro. Vibes weren't obnoxious (i already roll with a trz rmm & tmm) noises was biggest increase. But that was a stop gap until i could install the roca mount i bought off deadwayt. I received it and painted it a high temp / oil resistant matte black. I did the install, piece of cake.

Even though this is a stockish style replacement, you still have to relocate the ground strap.

Compared to the jbr, it is significantly lighter. I already tossed my busted stocker, so i can't compare to that. But I'd guess it's probably a little lighter? The aluminum is light. Fitment was good. Vibes and noise are stock-like. But, I've barely driven. I'll update later. For now, here are pics of it painted. I forgot to do before pics.

ok now i've driven quite a bit on this mount. i don't see how anyone could complain about vibes with it. (i have seen multiple people say they didn't like the increase in vibes) this thing feels completely stock to me, honestly. i suppose that with the TRZ TMM installed already, i won't feel much of anything.

so, i guess i'll say that this is a great mount so far. better than stock in that it won't explode. i don't make huge power, so i don't know how it would hold up with a big HP engine. but, if you're not a brand whore, it is probably worth a shot.

[azazelthegreat]

4 months later it's still holding up just fine.
During the winter NVH is horrible but whatever i got used to it.
Car feels alot better after replacing the stock one.

For the price i think it's well worth it.

As stated above if you're not making big power this mount will be good enough.

Huh just found out my PMM was collapsed im gonna go this route for now can't beat that price. How is everyone doing with theirs so far? Only con i see so far is bad vibes in the cold.

[sidekick]

i haven't had any problems with it. i just looked at it (i already had the hood up) and it still looks the same as when i installed it. vibes aren't bad for me at all. but, i have the TRZ trans mount so i already have vibe city.

Good to hear, I don't wana have them race car vibes and saving money is always a good thing. Ill have to get this for sure then. Its odd it says its for a mazda 3, do the speed and regular 3 mounts match up that much?

[fish20bcm]

Ordered one as well, interested to see how it holds up, price is definitely right.
